Being a computer technician pays nice money and has for a very long time. Why?well,mainly becuase alot of new computer owners fail to learn how to use and maintain there new computer.

This gives you somewhat of an idea about what we have here today..Alot of people now are getting computers becuase there friends have one,or to just get into the chat rooms,or the adult sites..point being..they dont know how to use a computer,much less maintain one.
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.

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.

I own a computer consulting business. I have been working with computers for the last 16 years. The most common question that I get from many of my home user customers is “What computer should I buy?” There are so many different configurations and choices when you go to purchase a computer that it makes it difficult unless you know what the computer parts are, even then you still have many different choices. Most people just want to purchase computer quickly and would rather that someone just help them pick the one that would best suit their needs without trying to learn about all of the details. I can certainly understand that. For example, I personally don’t want to know the details about how my plumbing works. I would just like the plumber to fix the problem or do what is needed without hassling me with the details. But then you have that issue with being able to trust what someone is recommending you purchase. Is it really a good deal and is the sales person really recommending the best computer for your needs. Most of the sales people I have to believe are doing their very best to help you make the correct choice but it is better that you understand some of the basic details/components about the computer that you are getting ready to purchase to make the sales persons job easier and to better understand what the options are for you when you are shopping around.
Hardware is the most important aspect of a computer. However, a majority of people focus on buying quality software for their computer and finally end with replacing them over and over again due to frequent attacks by viruses and spywares. The fact is that your computer won’t function properly until you purchase good quality computer hardware for yourself. Once you purchase quality computer hardware you’ll be free from any hardware problems.
