How Do Viruses And Worms Affect Your Computer

techno

Also, unlike viruses that most commonly infect an individual computer, the worms usually attack a computer network. A computer network functions by using a collection of servers and routers. This is what the internet is comprised of. A server is like a PC but has more speed and storage and a router is a server with specialized functions, it directs traffic through the network.
PC Security – Worm Viruses, Deadliest of All

A virus attacks the unit used to run programs on the computer called the central processing unit or CPU for short. It does this by running programs and being constantly busy, so that none of the functions you select can be opened. Similarly, this is how a worm functions on a network. The routers rely on memory and processing time (similar to the CPU functions). These are attacked and as a result the network drastically slows down.

Worms carry payloads which are comprised of other types of malware, backdoor installations or spyware. Spyware is a monitoring program that can keep an eye on activities on your computer and backdoor programs set up hidden access points used by hackers to steal your information or send spam.

My Doom sent out at the beginning of 2004, was the fastest spreading worm to date. The worm came in the form of an email with the message “andy; I’m just doing my job, nothing personal, sorry.”

Although the culprit was never found, its intended victim is thought to have been a software company called Santa Cruz Operation or SCO for short.

When a person opened this email, the worm was programmed to overwhelm SCO’s website with traffic. The worm spread through the internet and caused a massive slow down.

For the individual computer, the worm’s payload is more serious because it allows ports to be opened on the computer where hackers have access to steal or delete information. In addition, a payload may come with a program to attack your antivirus software and disable it.

De worming

Using firewalls will help protect your computer. Firewalls reduce traffic and hide your computer. In this state, you are less likely to be attacked by worms spread over the network.

Be careful not to open suspicious emails and if you don’t know the person or get and unexpected email don’t open it. If you find your computer is slow and reboots by itself or the internet is sluggish, you may have been infected. Try running antivirus software to check it out. If that doesn’t work, try to manually removing the virus. Information as to how this is done can be found on the internet.

Computer Chairs For Fat People

techno14

As much as youd like to deny it, our lives change when we become overweight. Computer chairs for fat people arent just a gimmick, they are a real necessity. If youve ever had a computer chair break under you, you know exactly what Im talking about. Chances are, if you weigh more than the 200 lbs that average chairs are designed to support, you have been dumped on the floor at least once by an office chair that just didnt hold up properly.

Fortunately, there really are computer chairs for fat people, designed with wider, heavier bodies in mind. These chairs are created with metal cores to prevent those embarrassing incidents where a leg snaps off and leaves you sprawling on the floor.

Being overweight is rarely a choice. You may be working very hard to lose weight, but in the meantime, you dont want to be breaking every chair you buy after just a couple of weeks. Thats why you should consider investing in sturdier, stronger computer chairs that will hold up under more weight.

Not only are computer chairs for fat people built to withstand more weight, they are also built to help you sit in the right posture and to give your body the support it needs. You see, our backs tend to be in pretty bad shape thanks to the extra weight we carry around, so it makes sense that we would need that extra lumbar support. Stay away from chairs that arent ergonomically correct, since they will only mess your back up more.

Choosing a computer chair shouldnt be rocket science. Look for one that has metal in all the important places and that offers back support. You should also check the weight limit. While some heavy office chairs are designed to hold up to 300 lbs, there are some specialized chairs that will easily stand up to 500 lbs and are virtually tank proof. This is what you need if youre heavier and want a chair that will last a little longer.

Unfortunately, these heavier chairs are more expensive than your average office chair. However, youll be able to use them for a very long time, since the legs and arms wont snap off like the usual cheap office chairs. Its a long term investment that will really pay off. You wont have to keep buying those darn breakable chairs and youll avoid the humiliation that comes with breaking chairs.

Computer chairs for fat people really are worth it. You can avoid a lot of pain and embarrassment just by investing a bit more in a chair that is actually built to hold you.

Running Two Projectors With One Computer

techno6

For some occasions, you might want to run two projectors by using one computer in the same time. In this case, you should know that some computers will allow you to simultaneously plug multiple projectors. This is because those computers especially desktops have two video graphics array connectors.

However, you might have computer that does not have the dual VGA connectors. For this condition, you should purchase a VGA splitter. This equipment will divide the signal to allow you playing the graphics through tow projectors that you have. With this way, you will find that the image that you will get is not as clear as that you want. But, you will find that the difference is barely noticeable if you only split it once. The followings brief description on how you can run two projectors with one computer.

Firstly, you should purchase a VGA splitter. This is the most first thing that you should do. You can buy this equipment in the electronics supply stores in your area. The price for this equipment is a about $10 to $20 or more.

Secondly, you should connect the VGA splitter that you have purchased to the VGA port in your computer. You will find that the port for VGA is generally blue and it has 15 holes for pins.

Thirdly, you should use split wires to connect the projectors. For this, you should use VGA cables that appropriate with your projectors. If the input of your projectors is also a VGA port, you can use a cable with a VGA plug on one side of the cable. But, you should use a plug for VGA with three prongs output if you use a component projector.

Fourthly, you should power on your projectors and your computer before calibrating the projectors. You will find that calibrating your projectors will depend on the specific projectors that you have, but you should set the input before running it through the computer that you use.

Reasons Your Computer Chairs Break

techno

Sadly, its not uncommon to have computer chairs snap under you. You might not even be that heavy, but chairs just arent made as well these days! Remember back when they were all metal? Those suckers withstood anything. These days, plastic is all youll find in most computer chairs. Overweight people tend to have even more problems since chairs often last only a few weeks before something breaks.

While you can keep using the chair without an arm or even if the back cracks and ends up at a weird angle (yes, this happens to many of us!), once the support column or one of the wheels or base legs goes, youre pretty much hooped. Many people cobble together Frankenchairs, made from a base that still functions with a seat that is still intact, just to save a bit of money. It might seem silly, but if you have computer chairs break on you every couple of months, this is what happens.

So, why do your chairs break? Here are three main reasons:

1. Its not built for weight. Most computer chairs are designed to withstand 150-200 lbs. So, if you weigh anything over that, your chair isnt going to last very long. Thats why you might want to look at computer chairs for overweight people, which can be rated for up to 500 lbs.

2. The material is poorly made. Unfortunately, there arent many high standards in the world of office chairs. Overweight people have discovered that plastic simply isnt designed to withstand much weight . . . it twists and bends and eventually cracks under the stress. These chairs are often stamped out of low cost plastic, which is not sturdy enough.

3. You move too much. When a computer chair is working properly, it will roll smoothly over the floor. However, poorly built chairs cant hold up to the weight. They will sink down, essentially crushing the wheels against the caps and the wheels wont roll. When this happens, you will end up jerking the chair to move it and that puts extra stress on the already fragile joints.

Often its a combination of these three factors that causes a computer chair to give way. You will want to make sure that you choose your chair very carefully. There are a number of designs in computer chairs for overweight people that will hold more and resist more action. Even if you arent obese, choosing a sturdier chair can be a good investment in the long run.

Computer games are very obsessive, thus when playing your favorite game concentrating on other things is virtually impossible. Avid gamers cannot stop playing even when a delicious odor of a cooked meal comes from the kitchen. Indeed, even food cravings are not able to force a gamer stop playing.

Indeed, computer games are addictive which is especially bad for children. It is not a secret that many teenagers devote much of their spare time to various computer games, which means they usually neglect family obligations, school and study hours, as well as outdoor activities.

Multimedia Laptop Asus N55s Review

techno8

Asus launched N55S and this laptop is a multimedia laptop many users may like. This multimedia powerhouse has a full HD display, Blu-ray writer, bang speakers, plus a 2GB Nvidia graphics card for playing the latest games. Many users like it because of the excellent anti-glare full HD screen, great performance, and decent speakers. But many may still be disappointed by the strange keyboard and loud touchpad buttons. And the following are some details about this laptop.

In terms of the overall design, the N55S is constructed of plastic and reasonably strong plastic at that; the palm rest barely flexes when pressed down upon. I’m greatly appreciative that ASUS used anti-glare plastic instead of glossy plastic, which is all too common on consumer notebooks. Chassis flex is average for a consumer notebook; nothing alarming, however. Fit and finish is good; there are no uneven gaps between parts or sharp edges.

In terms of laptop screen, the N55S has an excellent display compared to most consumer notebooks. This 15.6-inch model has a full HD resolution (1920×1080 pixels) which is appropriate given the notebook includes a Blu-ray drive and is designed for multimedia. Another admirable characteristic of the display is its anti-glare coating; this is more practical than a glossy coating since there are no reflections. The 1920×1080 resolution is excellent and the highest available on a 15.6-inch display. There is plenty of room to use two windows side-by-side and much less scrolling is required in web pages and programs like Microsoft Word since more lines of text are viewable at the same time.

In terms of laptop keyboard, the N55S has a keyboard that is best described as “strange”. It is traditionally styled; the keys don’t have extra spacing between them as they do on a ‘Chiclet’ or island-style keyboard. The key surface is flat with a downward-sloped front and has a nice smooth matte surface. Tactile feedback is good if a bit lifeless; more or less it’s pleasant to type. The keyboard is sufficiently quiet not to disturb neighbors.

And in terms of laptop battery life, the N55S lasted four hours and five minutes during our standard battery rundown test. This is a respectable time for a high-performance notebook like this one especially considering it has a quad-core processor. The Nvidia Optimus technology allows the N55S to switch to the low-power integrated Intel graphics and turn off the high-performance Nvidia GeForce graphics card when not needed to conserve power.

Taking all the above into conclusion, the ASUS N55S is a good value and a good buy. It has a great full HD display, good looks, and decent build quality. The performance is excellent; this notebook is more than capable of playing the latest games. Most of the cons for this notebook can be summed up as could have been better rather than simply bad.
