Are computer viruses spread by the media?

If you believe what you hear in the media, there are an awful lot of viruses going around. No, I'm not talking about the make-you-sick kind of virus, though they get plenty of airtime, too. I'm talking about the kind of virus that enters via your internet connection rather than your nasal passages.

What the mainstream media often don't tell you--at least, in most radio and television newscasts and in the crucial headlines and opening paragraphs of newspaper articles-- is that many of these "viruses" are not viruses at all.

What Computer Viruses Really Are

The main reason the mainstream media always are in alarm over viruses is that they tend to call any malicious computer program a virus. In reality, there are at least eleven distinct types of malicious software, or malware, commonly affecting computers today. The most common of these are worms, Trojans, and spyware.

So, what's the difference between computer viruses and the other types of malware? The difference is that computer viruses are just about the only ones that regularly shut down computers and cause other obvious damage. The most common of the other kinds of malware--worms, Trojans, and spyware--are usually only detectable with a special scan.

The Real Danger of Computer Viruses

If the other types of malware are so unobtrusive that they can only be detected with a special scan, then what's to worry about? For starters, these programs are called malicious for a reason: they are designed to cause some kind of damage, if not to your computer, then to someone else's.

Worms are most famously used to damage, destroy, or disrupt other computer networks than the one on which the host computer is located. For instance, worms have been used by website owners to shut down rival websites by sending overwhelming numbers of requests to the computer that hosts that website. Worms have also been used to send out viruses to other computers, often without infecting the host machine--after all, what would it benefit the worm to shut down its host computer?

Trojans, in turn, are often used to insert worms and other malware on your computer, even if the Trojan itself does no damage.

But even if you don't care what happens to anyone else, you should still be concerned about one kind of malware: spyware, a kind of malware that, true to its name, collects data from your computer and sends it back to a remote host.

Most spyware is only interested in monitoring your internet usage so it can tell other programs, called adware, what advertising to popup on your computer. However, there are criminal spyware programs that steal financial data, or perform a thorough identity theft. Don't think you have personal or financial data on your computer? Some spyware programs contain a keylogger, which is a program that copies whatever you type, usually in order to snatch passwords. Even if you keep no financial information on your computer, if you ever buy anything over the web, the keylogger would allow its owner to buy stuff using the same information you typed in to buy stuff yourself.

Why Blame the Media?

Computers - how they have advanced

Even over the last decade, the advances in computer technology have been immense

Even over the last decade, the advances in computer technology have been immense. Computers can do more today than ever before, faster and at a better value price. Unfortunately, this also means that shopping for a computer can be confusing, as it is hard to know what you actually need and what is just an extra that’s nice to have. Hopefully this article can clear up a few of the mysteries for you.

First of all, let’s look at processors. The two main companies producing processors today are Intel (Pentium processors) and AMD (Athlon processors). Although fanatics on each side swear otherwise, there is little difference between them, performance-wise. In almost all cases, more expensive processors will simply run faster.

However, it is important to consider that the performance of your processor can be limited by how much memory (RAM) your computer has. For high-end processors, you should make sure to get at least a gigabyte of RAM, although lower-end systems will be fine with less. RAM is especially important if you plan to use the system for gaming or other graphics-intensive applications.

Hard disk space, at this point, probably isn’t worth caring too much about. Even the cheapest computers now come with ridiculous amounts of hard disk space, far more than you are ever likely to use. It is much better to upgrade to a DVD re-writer drive than to upgrade your hard disk space. DVDs hold so much data that however big your hard drive is, it is unlikely to hold more than a cheap spindle of DVD-RW discs – and they’re re-writable, so you only need to buy them once.

The only other thing you really need to worry about is the graphics card (sound cards are all the same these days). Again, if you’re going to be doing anything graphically-intensive, then research this further and get a good one (be warned that it can be expensive). For the average user, though, the graphics card that comes with the processor is likely to be fine, even for many less-demanding or older games.

Adware: Are Your Business's Computers Secure?

Adware, software dedicated to displaying advertising, can really slow down any business that depends on computers. Adware promoters use some cunning tricks to get you to install their software on your machine. Here's what to look out for.

Adware is, by definition, something reasonable people don't want on their computers. That's why adware can't just come out and ask people to install it. Often, the computer owner is completely unaware of it being installed. But not always.

When adware doesn't want to sneak in through an open window, it will try to trick you into letting it in through the front door. Don't think you could be tricked? Don't be so sure until you've checked out these most common ways people have been tricked into allowing malware to be installed on their machines.


Adware Installation Trick 1: Piggybacking

How it works: malware may come bundled with a legitimate piece of software the user actually wants, such as a game or emoticon. The malware is merely labeled "companion software," without any indication of what it will do.

How to fight it: the fact that adware so often comes bundled with "entertainment" software, most notably the file-swapping program Kazaa, is a very good reason to separate business from personal when it comes to computing. But adware can sometimes comes bundled with non-entertainment software, such as search tools or cracks of legitimate business software. Be very suspicious of any software that comes bundled with other software. Don't installed software that comes bundled with other software unless you know everything that the bundled software does. After all, if the bundled program has anything to do with the program you actually want, why couldn't the software developer just get both programs' functionalities into a single piece of software? Software developers are now very sensitive to malware concerns and will provide a lengthy explanation of just why the bundled software is necessary, in the cases when they actually do need to use bundled software.


Adware Installation Trick 2: Bait and Switch

How it works: since people are getting more and more suspicious of bundled software, the program's developers may simply label it as valuable software, for instance, a browser plugin that supposedly accelerates web browsing (but in reality only shows ads).

How to fight it: again, a suspicious mind is useful in avoiding malware. Ask yourself some questions:

* What will this software actually do? Adware and adware-bundled software often come with very fuzzy claims attached. Sure, it says it will improve your browsing experience, but how? Often, this improved browsing experience just means a browsing experience with more advertising.

* If the software is so great, why is it being given away free? Most commonly, software is only given out free in two cases: if it's OpenSource (designed by a community of developers and not proprietary–OpenSource software is always clearly labeled as such); or simply a come-on for a fuller-featured version of the software. If neither case is true, there's a real chance the software is financed by adware.


Adware Installation Trick 3: Outright Lying

How it works: adware may even be labeled as something else entirely, such as a well-known piece of software or a crucial component of the computer operating system.

How to fight it: this is the trickiest adware of all, and requires extreme caution. You don't want to start deleting any of your program files, much less your system registry entries, unless you're absolutely sure it's malware. Plenty of overzealous parasite hunters have shot their own machines to bits this way. This is one case where you want to be using an anti-spyware program, and preferably a second anti-spyware program to provide a second opinion.


Getting Rid of Adware

Adware is so tricky that trying to uninstall it by yourself could be like a trip into the Matrix. Luckily, there are good anti-spyware programs that tackle adware as well–after all many adware programs are also spyware since they monitor your internet usage.

True, it may feel like adding insult to injury to have to install more software to get rid of software you never meant to install in the first place. But keeping your computer free of adware is just one new cost of doing business.

Computer Speakers - which ones?

Few people think too long and hard about their computer speakers

Few people think too long and hard about their computer speakers, instead preferring to just use the ones that came with their computers. These speakers are often built-in and poor quality, especially on laptop systems, and do not do justice to the very good sound quality that most computers are capable of producing.

The price range in computer speakers is even greater than that in other electronic products – you can pay anywhere from the price of a pair of headphones to as much as the computer itself cost you. It is natural, therefore, to be unsure of exactly what your money is getting you, which is where this article can hopefully be of some help.

Perhaps the most important thing you should look for when choosing your speakers is their maximum output power, which is measured in watts. This number tells you how good the speakers will sound at different volumes – while almost all speakers can sound good at low volumes, only ones with very high maximum output power will sound good at higher volumes. The higher the volume you plan to use, the more power you need.

Another important consideration is whether the speakers can produce either 5-speaker or 7-speaker surround sound, which makes a big difference over traditional 2-speaker systems. You should also check whether the speakers come with a subwoofer, which is a special loudspeaker for bass, allowing you to better hear the beat of your music. However, many people actually consider subwoofers undesirable, as they are so large and don’t always fit in well with a computer setup.

It is only really worth splashing out on speakers if you often use your computer for gaming or for playing music. If you do, then you might consider that there’s nothing to say so-called ‘computer’ speakers are only for computers – with a little imaginative wiring, you can also hook them up to televisions, games consoles, mp3 players, and all sorts of other things besides. This works in reverse, too, so if you already have a good pair of speakers, it should be relatively simple to connect them up to your computer and get some very good sound that way.

Owing a computer is almost essential in today’s world. With the introduction of the internet and the convenience of email as a method of communication, it’s easy to see why most people want to have a computer in their home or office.

Computers are like anything else and there are times when they don’t operate as planned. It’s frustrating to be sitting at your desk ready to play a game or work on a document only to find that your computer isn’t being cooperative.

When it comes to computer repair it’s often wise to seek out professional help. A computer technician is specially trained to evaluate the problem and offer the best possible solution.

There are certain types of computer repair that you might want to undertake yourself. These are usually minor fixes that can be handled with a bit of instruction and attention to detail.

A computer repair that you might be able to take care of yourself is the replacement of the computer’s battery or fan. Every desktop computer has a fan inside of it. This fan is used to keep the computer’s components cool. It’s essential that the fan operates efficiently to ensure that the computer doesn’t become overheated.

The first sign that your computer’s fan might not be operating properly is that you’ll notice a different sound when you start or run your computer. Instead of immediately taking it to a computer repair shop, take a moment to test the fan.

Computers typically have two fans. One is used to cool the power supply and the other is used to cool the CPU. Open the cover of the computer and listen. If the sound does appear to be coming from the fan that cools the CPU you’ll want to replace it.

If the computer is still under warranty than this type of computer repair will be done free of charge. Follow the instructions you were given for repairs at the time of purchase. If the warranty period has elapsed you can either take it to a computer repair shop or do it yourself.

The very first and most important step when doing any computer repair is to unplug the computer from the electrical outlet. You’ll then need to examine the fan to see how it’s connected. It will probably be attached by a few small screws. Once these are loosened you’ll need to disconnect the fan from its power supply. This will be one or two small clips. Then take the fan to your computer repair shop and purchase a new one.

After replacing it, reattach the cover and plug the machine in. The fan should operate perfectly now and the noise that you were hearing will have disappeared.

Sometimes a computer will make noises because a piece of hardware isn’t attached properly. One of the likely culprits is the CD-Rom or DVD drive. Again for this type of computer repair, you’ll want to carefully remove the cover and listen for the source of the noise. After tightening the screws that hold the hardware in place and reattaching the cover, plug the machine in and listen if the offending noise is gone.

When it comes to computer repair it’s important to be safe and thorough. Computers are an expensive investment and keeping them running efficiently is crucial. If you are comfortable handling a small computer repair yourself, give it a try. If you’re not comfortable, take the machine to a local computer repair shop and allow the experts to do their job.

Laptop Computers

A laptop is a personal computer which is portable. It may also be known as a notebook. The typical laptop will only weight a few pounds and will generally have an internal battery as well as a power adapter.

A laptop is a personal computer which is portable. It may also be known as a notebook. The typical laptop will range in weight from 1 to 3 kilograms, and will generally have an internal battery as well as a power adapter. While most laptops are portable, few can currently match the power of the most expensive desktops, though this will likely change as technology continues to advance. The word laptop was first introduced in 1983, and was used to refer to the Gavilan SC.

Despite the name, most laptops should not be placed in your lap if it is not covered, because they can get hot, and can even burn skin that is held against it for extended periods of time. The typical laptop can be powered by one battery, and the power adapter can power the battery when it is plugged into a wall outlet. A laptop can perform many of the same tasks as a PC, but they tend to be limited. They will have the same internal devices which are seen in desktops, but they will be much smaller in size. Most laptops will have a screen which uses a liquid crystal display.

Most manufacturers have designed their laptops to work with a keyboard and mouse, and they will also have a touch pad that can be used to move around the cursor on the screen. Laptops come in three varieties, and these are based on the size. An ultraportable laptop will generally weigh less than 1.7 kilograms, while a thin and light laptop will weigh up to 2.8 kilograms, and a medium sized laptop will weigh up to 3.5 kilograms. The idea for the laptop existed prior to the invention of the personal computer, and was first conceived during the 1970s. The very first laptop was the Osborne 1, and it was released in 1981.

While the Osborne 1 was massive in comparison to contemporary laptops, it was revolutionary for its time, because it allowed people to carry their data with them, and the computer didn't have to be left in a single location. However, the Osborne 1 was so large that it was not possible to run it on a battery. Most laptops today now use lithium ion batteries. While laptops have a few advantages over their desktop counterparts, they have some disadvantages as well. Unlike desktops, they are limited in their ability to be upgraded. As of this writing, their is no form factor for laptops, and the costs and technical issues involved with making them easy to upgrade aren't feasible.

The only parts of most laptops that can easily be upgraded are the hard drive and RAM. In addition to this, laptops are expensive to repair if they are damaged, and they are also easy to steal due to their small size. Stolen laptops are a common cause for identity theft. While the use of the USB port has allowed laptops to be upgraded to some degree, it will typically reduce their portability. Historically, the performance of laptops has always been low when they were compared to desktops in the same price range.

There are various accessories that could help operating a computer easier. The mouse is just an example of an accessory which makes navigation simple with just one click. However, most of these accessories have short “lifespan” and can be considered disposable. This is when the accessories can become bothersome.

What are you to do, when in the middle of an important document, your mouse decides to “die”? Would you worry? Would you panic and run to the nearest store? What if it’s night time and the stores are closed and you are rushing up your work?

On your keyboard, immediately press CTRL + S simultaneously to save whatever it is you’re doing. That way, you don’t lose your work. This is a common and one of the most familiar tasks without using the mouse. If the mouse is not functioning and you need to do something important but you don’t have the time to repair the mouse or change it, you can actually still do your work even with just the keyboard around. Here are some key combinations you need to navigate your way through your PC sans the mouse:

Ctrl + O – to open a file or document
Ctrl + B – to use the “Bold” feature of fonts
Ctrl + I – to italize fonts
Ctrl + U – to underline texts in a document
Ctrl + X – to cut texts, cells, or icons from files
Ctrl + W – to close existing windows
Ctrl + R – to align document to the right

More than anything else, the main goal of computer ergonomics to work to reduce repetitive stress injuries that can result through the regular use of a computer and related equipment. Through this article, a brief overview of repetitive stress injuries is provided, particularly as these injuries relate to computer use and computer ergonomics.

Generally speaking, repetitive stress injuries are referred to by many experts in the field of computer ergonomics as Cumulative Trauma Disorders. As the moniker suggests, the key to understanding and appreciating Cumulative Trauma Disorders is appreciating that they are, in fact, cumulative. In other words, these injuries develop overtime from repetitive movements, strained exertions, working in awkward positions as well as from compression and vibration.

Most people assume that when it comes to Cumulative Trauma Disorders, exposure to the source of a trauma needs to be for a lengthy period of time. In many instances, this assumption does prove correct. However, in reality, it is impossible to develop Cumulative Trauma Disorders after exposure to a source for a matter of weeks. As a result, it truly is important for a person to follow the suggestions of computer ergonomics specialists.

The symptoms of repetitive stress injuries or Cumulative Trauma Disorders include severe pain, tissue swelling, numbness, unusual tingling, restriction of natural joint movement and, ultimately, decreased dexterity.

If you are in fact experiencing one or more of these symptoms, it is absolutely necessary for you to seek prompt and immediate medical attention. By seeking medical attention in the first instance, you have a far better chance of alleviating the symptoms and the underlying traumatic condition. In addition, by seeking prompt medical attention, you are far more likely to avoid a more invasive medical procedure such as surgery to resolve an injury or disorder.

When all is said and done, repetitive stress injuries or Cumulative Trauma Disorders simply are not matters which should be taken lightly. Rather, as has been noted, if you feel that you are suffering from one or another of the symptoms outlined in this article, you should waste no time in obtaining medical attention and assistance. Further, as has been noted, you can avoid or lessen the harmful side effects of computer use by following the guidelines established by experts in the field of computer ergonomics. Truly, an ounce of prevention is worth a pound of cure in the case of Cumulative Trauma Disorders.

Sony Laptops Are Still Part Of The Sony Family

Sony laptops are among the most well known laptops on today’s market

Sony laptops are among the most well known laptops on today’s market. Sony is a name that over time has established itself as creating a solid product with a stellar reputation. In addition to all the good press that Sony has, Sony is known for making the best ‘small’ laptops. This means that they pack a ton of features into a much smaller packet and do it better than most laptop companies around.

If you are in the market for a laptop it makes perfect sense to look around, compare your options and decide on the laptop that will ultimately work best for you. There are many companies out there that offer similar products; some are superior, some inferior, some at a premium price, and still others at bargain prices. The laptop industry isn’t always an industry where you get what you pay for.

When choosing a laptop, it is never a good idea to buy what others think you should buy, buy the laptop that has the features that you need at a price that you can afford. Don’t buy a laptop that has bells and whistles you will never utilize. Perhaps, that is what I like most about Sony and the products they offer. Sony Laptops aren’t about stuffing computers full of features that will never be useful to the average consumer. Instead, they build a computer that the average consumer can use and offer upgrades beyond their basic computer setup.

When you buy a Sony laptop you are not only buying a great laptop, you are buying a solid name from a company that over time has proven it will stand behind its products and services. Sony products have been around for years and the company is on solid ground, they will be around for years to come. Their laptops are made with the same attention to detail and technological evolution that has made Sony famous, that being said, it’s a fair assessment that a Sony laptop is a good investment as far as laptops go.

Is Your PC Crowding Your Desk?

When your PC eats up almost the entire space in your computer table, it’s time to have a little re-organizing. Desktop computers, especially those bulky CPU’s and monitors could eat up quite a space which could be a room for other essentials such as folder stackers, telephone or fax machine. Nowadays, bulky personal computers can be really heavy to the eyes, especially since in today’s technology, the adage, “bulk is out, thin is in” is the mainstream.

When your PC eats up almost the entire space in your computer table, it’s time to have a little re-organizing. Desktop computers, especially those bulky CPU’s and monitors could eat up quite a space which could be a room for other essentials such as folder stackers, telephone or fax machine. Nowadays, bulky personal computers can be really heavy to the eyes, especially since in today’s technology, the adage, “bulk is out, thin is in” is the mainstream.

Let’s start with your computer table. Its size may vary depending on your design. It may be wide enough to accommodate two “bulky” PC sets, or it could barely hold one, and you don’t have enough space left for the keyboard or the mouse.

First things first, remove all unnecessary files, folders, papers, trash, coffee mugs and saucers, ashtrays, etc. on your desk. Clear the area. Your computer table should be just that, a computer table and not a hodgepodge of everything else. However, top designers say that there are some essential things that should be within reach (especially for an office desk).

The telephone, for one should be within reach. Some very important and frequently used documents could be stacked inside an upright holder which can cover only a little space and is still within reach compared to when just piled up on top of the table.

However, if the area is already clear, but you can still barely fit a small pen holder on top of it, you should think of getting yourself a bigger desk or… a new set of personal computer.

Super space-saving computers have flooded the market nowadays. Try checking out flat monitors to replace your old, bulky one. Have your CPU re-designed or buy one of those small and slim tower CPUs. Small and compact keyboards are also available, reducing the size of a regular keyboard to almost a half.

And, if you do not have a place to slide your mouse in, try using a trackball mouse. That way, it occupies just that small space and you don’t have to glide it across a wider area.

Or have all of those pieces in one super sleek laptop notebook. People on the go prefer to have a laptop which they can take along whenever and wherever they go. And nowadays, laptops are not at all far behind in terms of technical capabilities vis-à-vis PCs.

It is always a good thing to see a clear and organized computer table. It would compel one to work well, without the mess adding up to the already full and cluttered working brain. And, admit it, it’s nice not seeing those bulky gadgets anymore. It helps ease the heaviness in the mind as well.

Indeed, there are many misconceptions when it comes to seeking ergonomically designed computer equipment, furniture and other products in the 21st century.

Most people who are considering office furniture tend to look for a chair with a back that will allow them to sit up straight. In point of fact, sitting up straight is not really the best position to take when you are working at your computer. Indeed, there are many misconceptions when it comes to seeking ergonomically designed computer equipment, furniture and other products in the 21st century.

Turning for the moment to the matter of the best type of chair to use when using your computer, as has just been referenced, sitting up straight really is not the best course of action for you. Sitting at a ninety degree angle is not the healthiest way in which to work -- no matter what experts may have indicated for a significant period of time in the past.

In point of fact, sitting at a rigid and ninety degree angle is not comfortable for an extended period of time. Sitting in this manner can, in fact, be very uncomfortable.

There is a simple principle that is applied when considering ergonomics generally and computer ergonomics specifically: if it is not comfortable, it probably is not an ergonomically designed piece of furniture or equipment. In point of fact and generally speaking, when it comes to ergonomically designed products, comfort really does normally equate with propriety and proper design.

The human body is a remarkable machine. It can send your brain warning signals whenever it is not properly positioned; hence, the discomfort you feel when you are not seated properly or using appropriately designed equipment and products.

In this day and age, there are a number of useful resources available to a person who is interested in finding out more about ergonomics generally and computer ergonomics specifically. Much of this material readily is available on the Internet and World Wide Web.

Your Information Technology Career: Certification vs. Experience

Whether you're starting or jumpstarting your IT career, the "certification vs. experience" question is going to come up. Chris Bryant, CCIE #12933, tells you how to get the best of both worlds.

Whether you're just starting your Information Technology career, or wanting to get further ahead in your current IT career, you have probably thought about earning one of the many popular computer certifications such as the Cisco Certified Network Associate (CCNA) certification, or the MCSE (Microsoft Certified Systems Engineer) cert.

A major point of frustration for individuals pursuing one of these certifications is a possible lack of experience with these technologies. Many future CCNAs or MCSEs simply stop trying to earn their certification, feeling that their lack of experience will hold them back.

Adding to this are those in IT who will stop everything they're doing at the drop of a hat to stomp on the dreams of others. I recently saw a post by an IT newcomer on a popular website where he declared his intention of earning his CCNA. Within minutes, several naysayers popped up and told him that he shouldn't bother, it wouldn't do any good due to his lack of experience, etc. (Did you ever notice that people who bash certifications generally don't have any themselves?)

I am in no way discounting the importance of experience. What I am saying is that every single one of us was a beginner at one point, and a lot of IT professionals forget this. None of us was born knowing everything we know today, and we shouldn't spend any time dismissing the goals of others in the IT field, or those just breaking in.


I am speaking from experience on this point. I had a tough time breaking into the IT field, and made a lot of calls and knocked on a lot of doors before I got in. I found out later that the reason I got that entry-level job is that I had a professional certification where the other candidates did not.

The pursuit of certification is the pursuit of knowledge, and in our field, you can never have too much knowledge. If your work is strictly on the Local Area Network side, don't let that stop you from pursuing a CCNA. If you work exclusively on the WAN side, don't let that stop you from going after your MCSE. If you're just breaking into Information Technology, don't let a lack of experience prevent you from studying for your A+, Network+, or even your MCSE or CCNA.

Because one day, opportunity is going to knock - and the more you know, the readier you'll be to answer that knock! Use your long-range vision to envision the day when you will have both experience and certification - an unbeatable combination.

Computer Desks - think before you buy

Many people buy a computer, only to find that it doesn’t really fit anywhere. They can be big, awkwardly-shaped things, with a whole collection of wires and gadgets that all need somewhere to stand.

The solution is to get a computer desk. They don’t cost much, and they’re specially designed to hold all the peripherals a computer needs. There’s space for the monitor, speakers and mouse on the top, a shelf for the keyboard, and then compartments at the bottom for the system box itself and even for a printer or scanner. A good computer desk will also have holes and routes for all the various cables that are needed to tie it all together and make it work. All you need is a comfortable office chair, and you’re set.

With the rise of wireless networking, it is even possible to have computer desks in places you wouldn’t otherwise have thought of, as long as you have an electrical outlet handy. All you need to do is add a wireless card to the computer and plug the connection into a router, and then you can use the Internet without having to run network cables all over the place. This works especially well in offices, where lots of computer may be networked together, or, worse, networked to one printer or server.

In larger computing environments, it is possible to get big computer desks that are set up for multiple computers, making it easier for a team to work together on them. Some desks even come with computers integrated, meaning that the working parts of the computer can be hidden much better, a bit like a kitchen with built-in appliances. However, the downside of too much integration between the computers and the desks is that it can make the computers much more difficult to repair if they happen to break.

Maintain Your PC’s Performance With PC Programs

Over time, even the most sophisticated, memory packed computer can begin to run slow if we don’t do something to prevent it. The reason why has less to do with how computers are made and how they age and more to do with the way we use them. You see, all of the daily tasks that we do on our PC from running programs to downloading and deleting software can make our computer sluggish.

Over time, even the most sophisticated, memory packed computer can begin to run slow if we don’t do something to prevent it. The reason why has less to do with how computers are made and how they age and more to do with the way we use them. You see, all of the daily tasks that we do on our PC from running programs to downloading and deleting software can make our computer sluggish.

To keep this from happening, you need to understand the reasons why your PC is getting slower and do something to keep your PC running at its best. You can do this through regular maintenance and PC performance optimization programs.

Before we discuss all of the things that could be affecting your PC’s performance, let’s talk a little about what symptoms a slow computer can have.

In addition to being excruciatingly slow when it comes to opening programs or finishing tasks, your PC may also experience data loss, unwanted shutdowns, Windows crashing and Windows hang up. All of these can be very annoying to deal with and are a sure sign that you need to optimize your PC and maintain it.

There are many reasons why your PC is getting slower and not performing quite the way it used to. Any one of them may be just the thing that is holding your PC back. In some cases, there is more than one culprit at work. But there are solutions to keep your computer from being affected by these nuisances, and we will talk about what you can do to maintain your PC and keep it running smoothly if it encounters any of these problems.

When you download and use programs on your PC, sometimes they are set up to start running as soon as you turn on your computer. These programs may be running in the background without you even knowing it and they use up precious memory needed for other tasks.

To see if you have any programs running in the background, press Ctrl + Alt + Delete at the same time.

A list of all of the currently running programs will appear in a pop up window. You can choose to stop the programs by highlighting the program and clicking “end task.” If you want to keep those programs from starting when you turn on your PC, change the individual settings for each program so that they will not automatically be turned on.

Memory is a computer component that allows it to do all of the various tasks that you require of it. When you start to do a task, a segment of memory is assigned to that task. If you don’t have enough memory and you try to do several tasks at once, you may run out of memory and not be able to perform any tasks properly. In order to optimize and maintain memory, you can use a Memory Optimizer program. This program changes the way that Windows manages memory so that you can use it more efficiently.

Your hard drive is like a huge filing cabinet containing all of the files that you need for your computer to perform properly. When you add programs, files are added to this data base. When you delete data or programs, files are removed. This process results in holes or empty spaces in your filing cabinet.

These holes make it harder for your computer to work because it continuously has to search for information over a larger distance and sometimes search for information that is completely out of order. To combat this, you need to defragment your hard drive. You can do this with your Windows system optimization tools or with a Registry Deffrager and Optimizer. These programs eliminate holes and arrange your files in a sensible order.

Just as your PC’s hard drive could be filed improperly, it can also be too full to work at its best. A good rule of thumb is to have at least 2MB to 3MB of space on your hard drive for your PC to function properly. To free up space, simply delete unused programs on the C: drive.

Maintaining your PC’s performance is vital if you want you computer to always complete tasks at its top speed. While Windows has some system tools to help you do this, they do not work on their own. You have to actually go and start the programs to optimize your computer. And they may not be enough. In this case, you may want to opt for optimization software such as PC Programs to help maintain your PC’s performance.

A Laptop of My Own

Working from home day after day and night after night on a borrowed laptop is no fun. Especially when it is borrowed back off you. So, for that reason, I feel the time has come for a laptop of my own. Or do I want a desktop? A PC or Apple Mac? Or maybe one of those little palm-held jobs would look the part; after all, it would fit neatly in my handbag.

After much consideration and deliberation, I go full circle and end up back at the laptop. But where do I start? What are my requirements? Well, my business is a small one, so I don't really require anything top of the range. Yet! I'll use it mainly for article writing and up-dating my website. Oh! And maybe a spot of shopping! And I will be the only one using it. Probably!

So I have a look on the internet to find out what other people are buying. And what manufacturers are selling. Suddenly the English language becomes muffled jargon. Do I really know what I want?

What memory is required? My husband, a programmer, insists 2GB is what is called for. Added to that is the essential 2.0TB of storage! Whatever all that means! I'm not so sure! I fear he may have his own reasons for these specifications...

Dell is mentioned; so I go online for a browse. Having found one within budget that appeals and appears to tick all the boxes, I am suddenly confronted with an array of extras - all of which serve to push up the price.

So I pull the reigns in. Perhaps I don't really need a lap-top of my own. Maybe my husband's will suffice after all.
Neither a borrower nor a lender be - well so much for Shakespeare - it seems to work for us...

Preventive maintenance software for computer hardware

Computers often break down at the worst of all times. These problems can be averted, or at least minimized with preventive maintenance. Several methods of keeping computer hardware in good working order deal with the external components of the computer, such as the keyboard and monitor. For example, it is important to keep the processor away from excess heat and moisture. There are also computer hardware preventive maintenance software programs that can help with the upkeep of other internal asp

Computers often break down at the worst of all times. These problems can be averted, or at least minimized with preventive maintenance. Several methods of keeping computer hardware in good working order deal with the external components of the computer, such as the keyboard and monitor. For example, it is important to keep the processor away from excess heat and moisture. There are also computer hardware preventive maintenance software programs that can help with the upkeep of other internal aspects of a computer.

While it is rare to find a CMMS that works on all of a computer’s hardware, many different programs can be utilized simultaneously. Some computers have periodic automatic updates available that can be downloaded and used to improve the computer’s performance. Other software programs, known as disk defragmenters, manage hard drive space so that software programs take less time to access. Programs known as hardware diagnostic utilities can check the computer’s hardware components and alert the user about any potential failures. Since some new hardware will not always work on all computers and could cause existing hardware to malfunction, it is important to have a CMMS program to ensure that the new hardware is compatible with existing hardware.

Antivirus programs are another important component of computer hardware preventive maintenance software. Computer viruses have become increasingly common in recent years and can render a good computer useless. While computer viruses mainly attack software programs, they can ruin hardware as well. Several manufacturers make reliable antivirus software. A couple of well-known companies are Norton and McAfee. As with much preventive maintenance software, these programs are usually available for a free trial period before the user must pay a subscription fee.

Computer hardware preventive maintenance software is necessary to keep computers in good working order. This software manages aspects of computer hardware that would be difficult and time-consuming for even the most computer savvy users.

Not to long ago I got a 17 inch notebook, and I must say that I'm quite impressed with its performance and quality. Technology has really improved and therefore this notebook is so much better than the old IBM Thinkpad that I had many years ago.

In those days, laptop computers were bulky and kind of big, the screen resolution was terrible, they were even more expensive than now, and the batteries had very low life expectancy. Thankfully my new Dell 17 inch notebook is everything that my old laptop was not. It is sleek, low-profile, with many hours of battery life, and a delightful high-resolution lcd screen.

I waited very long before I finally purchased my new 17 inch notebook. Don't you find the process of buying a new computer agonizing?

The problem I think we all experience is that no matter how long you wait, the very next month after you buy whatever system you have chosen to purchase, there is always something cheaper and better at a lower price and with a better warranty. It is enough to drive you completely nuts.

Nevertheless, I knew that the convenience of a new laptop computer was worth it, and eventually I broke down and bought my new 17 inch notebook. And I am sure glad that I did. There is nothing that beats a laptop computer.

The best thing about my 17 inch notebook is how easy it makes work on the go. With the prevalence of wifi coffee houses, I can work from my 17 inch notebook from all about town.

I do a considerable amount of freelancing, so the luxury of being able to do all my work on the go, when I want, and from where I want, makes my life almost feel like a permanent vacation. And when I am done with my 17 inch notebook, I slip it into my laptop computer sleeve, and can carry it around me anywhere.

It is no burden at all, because of its light weight, and though I occasionally worry about having it stolen, or accidentally damaged, so far no harm has come to my computer. My sturdy 17 inch notebook has really revolutionized my life.

Of course, for many people, getting a new 17 inch notebook computer like I have done might be a bad idea. If you are not good at keeping track of your stuff, it is a definite no. You could easily lose your 17 inch notebook computer, along with all of your work and data, due to one careless mistake.

How to protect your Computer. Wery useful Tips

Computer Security Ethics and Privacy
Today, many people rely on computers to do homework, work, and create or store useful information. Therefore, it is important for the information on the computer to be stored and kept properly. It is also extremely important for people on computers to protect their computer from data loss, misuse, and abuse.  For example, it is crucial for businesses to keep information they have secure so that hackers can’t access the information. Home users also need to take means to make sure that their credit card numbers are secure when they are participating in online transactions.  A computer security risk is any action that could cause lost of information, software, data, processing incompatibilities, or cause damage to computer hardware,   a lot of these are planned to do damage. An intentional breach in computer security is known as a computer crime which is slightly different from a cypercrime. A cybercrime is known as illegal acts based on the internet and is one of the FBI’s top priorities.  There are several distinct categories for people that cause cybercrimes, and they are refereed as hacker, cracker, cyberterrorist, cyberextortionist, unethical employee, script kiddie and corporate spy.  The term hacker was actually known as a good word but now it has a very negative view. A hacker is defined as someone who accesses a computer or computer network unlawfully.  They often claim that they do this to find leaks in the security of a network. The term cracker has never been associated with something positive this refers to someone how intentionally access a computer or computer network for evil reasons. It’s basically an evil hacker.  They access it with the intent of destroying, or stealing information. Both crackers and hackers are very advanced with network skills.  A cyberterrorist is someone who uses a computer network or the internet to destroy computers for political reasons.  It’s just like a regular terrorist attack because it requires highly skilled individuals, millions of dollars to implement, and years of planning. The term cyperextortionist is someone who uses emails as an offensive force. They would usually send a company a very threatening email stating that they will release some confidential information, exploit a security leak, or launch an attack that will harm a company’s network. They will request a paid amount to not proceed sort of like black mailing in a since. An unethical employee is an employee that illegally accesses their company’s network for numerous reasons. One could be the money they can get from selling top secret information, or some may be bitter and want revenge. A script kiddie is someone who is like a cracker because they may have the intentions of doing harm, but they usually lack the technical skills. They are usually silly teenagers that use prewritten hacking and cracking programs. A corporate spy has extremely high computer and network skills and is hired to break into a specific computer or computer network to steal or delete data and information. Shady companies hire these type people in a practice known as corporate espionage. They do this to gain an advantage over their competition an illegal practice. Business and home users must do their best to protect or safeguard their computers from security risks. The next part of this article will give some pointers to help protect your computer. However, one must remember that there is no one hundred percent guarantee way to protect your computer so becoming more knowledgeable about them is a must during these days. When you transfer information over a network it has a high security risk compared to information transmitted in a business network because the administrators usually take some extreme measures to help protect against security risks. Over the internet there is no powerful administrator which makes the risk a lot higher. If your not sure if your computer is vulnerable to a computer risk than you can always use some-type of online security service which is a website that checks your computer for email and Internet vulnerabilities. The company will then give some pointers on how to correct these vulnerabilities.  The Computer Emergency Response Team Coordination Center is a place that can do this. The typical network attacks that puts computers at risk includes viruses, worms, spoofing, Trojan horses, and denial of service attacks.  Every unprotected computer is vulnerable to a computer virus which is a potentially harming computer program that infects a computer negatively and altering the way the computer operates without the user’s consent. Once the virus is in the computer it can spread throughout infecting other files and potentially damaging the operating system itself. It’s similar to a bacteria virus that infects humans because it gets into the body through small openings and can spread to other parts of the body and can cause some damage. The similarity is, the best way to avoid is preparation.  A computer worm is a program that repeatedly copies itself and is very similar to a computer virus. However the difference is that a virus needs o attach itself to an executable file and become a part of it. A computer worm doesn’t need to do that I seems copies to itself and to other networks and eats up a lot of bandwidth. A Trojan Horse named after the famous Greek myth and is used to describe a program that secretly hides and actually looks like a legitimate program but is a fake.  A certain action usually triggers the Trojan horse, and unlike viruses and worms they don’t replicate itself. Computer viruses, worms, and Trojan horses are all classifies as malicious-logic programs which are just programs that deliberately harms a computer.  Although these are the common three there are many more variations and it would be almost impossible to list them. You know when a computer is infected by a virus, worm, or Trojan horse if one or more of these acts happen:

?    Screen shots of weird messages or pictures appear.
?    You have less available memory then you expected
?    Music or sounds plays randomly.
?    Files get corrupted
?    Programs are files don’t work properly
?    Unknown files or programs randomly appear
?    System properties fluctuate

Computer viruses, worms, and Trojan horses deliver their payload or instructions through four common ways. One, when an individual runs an infected program so if you download a lot of things you should always scan the files before executing, especially executable files. Second, is when an individual runs an infected program. Third, is when an individual bots a computer with an infected drive, so that’s why it’s important to not leave media files in your computer when you shut it down.  Fourth is when it connects an unprotected computer to a network. Today, a very common way that people get a computer virus, worm, or Trojan horse is when they open up an infected file through an email attachment. There are literally thousands of computer malicious logic programs and new one comes out by the numbers so that’s why it’s important to keep up to date with new ones that come out each day. Many websites keep track of this. There is no known method for completely protecting a computer or computer network from computer viruses, worms, and Trojan horses, but people can take several precautions to significantly reduce their chances of being infected by one of those malicious programs.  Whenever you start a computer you should have no removable media in he drives. This goes for CD, DVD, and floppy disks. When the computer starts up it tries to execute a bot sector on the drives and even if it’s unsuccessful any given various on the bot sector can infect the computer’s hard disk. If you must start the computer for a particular reason, such as the hard disk fails and you are trying to reformat the drive make sure that the disk is not infected.
