If you've never had a machine fall victim to a computer virus, you may wonder what the fuss is about. Computer viruses are just one kind of online threat, but they're arguably the best known of the bunch. Computer viruses have been around for many years. In fact, ina scientist named John von Neumann theorized that a self-replicated program was possible [source: Krebs ]. The computer industry wasn't even a decade old, and already someone had figured out how to throw a monkey wrench into the figurative gears.

But it took a few decades before programmers known as hackers began to build computer viruses. While some pranksters created virus-like programs for large computer systems, it was really the introduction of the personal computer that brought computer viruses to the public's attention.

A doctoral student named Fred Cohen was the first to describe self-replicating programs designed to modify computers as viruses. The name has stuck ever since. A hacker would save the virus to disks and then distribute the disks to other people.

It wasn't until modems became common that virus transmission became a real problem. Today when we think of a computer virus, we usually imagine something that transmits itself via the Internet.

It might infect computers through e-mail messages or corrupted Web links. Programs like these can spread much faster than the earliest computer viruses. We're going to take a look at 10 of the worst computer viruses to cripple a computer system. Let's start with the Melissa virus. In the spring ofa man named David L. Smith created a what is the common name for porifera virus based on a Microsoft Word macro. He built the virus so that it could spread through e-mail messages.

Smith named the virus "Melissa," saying that he named it after an exotic dancer from Florida [source: CNN ]. Rather than shaking its moneymaker, the Melissa computer virus tempts recipients into opening a document with an e-mail message like "Here is that document you asked for, don't show it to anybody else.

The virus spread rapidly after Smith unleashed it on the world. The United States federal government became very interested in Smith's work -- according to statements made by FBI officials to Congress, the Melissa virus "wreaked havoc on government and private sector networks" [source: FBI ]. The increase in e-mail traffic forced some companies to discontinue e-mail programs until the virus was contained.

After a lengthy trial what did the caveman actor use to keep cool answer, Smith lost his case and received a month jail sentence.

Ultimately, the Melissa virus didn't cripple the Internetbut it was one of the first computer viruses to get the public's attention. In this article, we'll look at several different kinds of computer viruses. Here's a quick guide to what we'll see:. Some of the earliest viruses to infect personal computers included the Apple Viruses, which attacked Apple II computers.

A year after the Melissa virus hit the Interneta digital menace emerged from the Philippines. Unlike the Melissa virus, this threat came in the form of a worm -- it was a standalone program capable of replicating itself. The subject of the e-mail said that the message was a love letter from a secret admirer. An attachment in the e-mail was what caused all the trouble.

The vbs extension pointed to the language the hacker used to create the worm: Visual Basic Scripting [source: McAfee ]. Some think it was Onel de Guzman of the Philippines. Filipino authorities investigated de Guzman on charges of theft -- at the time the Philippines had no computer espionage or sabotage laws. Citing a lack of evidence, the Filipino authorities dropped the charges against de Guzman, who would neither confirm nor deny his responsibility for the virus.

Now that the love fest is over, let's take a look at one of the most widespread viruses to hit the Web. As if viruses, worms and Trojan horses weren't enough, we also have to worry about virus hoaxes. These are fake viruses -- they don't actually cause any harm or replicate themselves.

Instead, the creators of these viruses hope that people and media companies treat the hoax as if it were the real deal. Even though these what the quran says about the bible aren't immediately dangerous, they are still a problem. Like the boy who cried wolf, hoax viruses can cause people to ignore warnings about real threats.

The Klez virus marked a new direction for computer viruse ssetting the bar high for those that would follow. It debuted in lateand variations of the virus plagued the Internet for several months.

The basic Klez worm infected a victim's computer through an e-mail message, replicated itself and then sent itself to people in the victim's address book. Some variations of the Klez virus carried other harmful programs that could render a victim's computer inoperable.

Depending on the version, the Klez virus could act like a normal computer virus, a worm or a Trojan horse. It could even disable virus-scanning software and pose as a virus-removal tool [source: Symantec ]. Shortly after it appeared on the Internethackers modified the Klez virus in a way that made it far more effective. Like other viruses, it could comb through a victim's address book and send itself to contacts.

But it could also take another name from the contact list and place that address in the "From" field in the e-mail client. It's called spoofing -- the e-mail appears to come from one source when it's really coming from somewhere else.

Spoofing an e-mail address accomplishes a couple of goals. For one thing, it doesn't do the recipient of the how to make a farmer on little alchemy any good to block the person in the "From" field, since the e-mails are really coming from someone else.

A Klez worm programmed to spam people with multiple e-mails could clog an inbox in short order, because how to write appellate brief recipients would be unable to tell what the real source of the problem was.

Also, the e-mail's recipient might recognize the name in the "From" field and therefore be more receptive to opening it. It's important to have an antivirus program on your computer, and to keep it up to date.

But you shouldn't use more than one suite, as multiple antivirus programs can interfere with one another. Here's a list of some antivirus software suites:. Several major computer viruses debuted in In the next section, we'll take a look at Code Red. Both worms exploited an operating system vulnerability that was found in machines running Windows and Windows NT. The vulnerability was a buffer overflow problemwhich means when a machine running on these operating systems receives more information than its buffers can handle, it starts to overwrite adjacent memory.

That means all the computers infected with Code Red tried to contact the Web servers at the White House at the same time, overloading the machines. That's because the worm creates a what channel is abc in albany ny into the computer's operating system, allowing a remote user to access and control the machine. In computing terms, this is a system-level compromiseand it's bad news for the computer's owner. The person behind the virus can access information from the victim's computer or even use the infected computer to commit crimes.

That means the victim not only has to deal with an infected computer, but also may fall under suspicion for crimes he or she didn't commit. While Windows NT machines were vulnerable to the Code Red worms, the viruses' effect on these machines wasn't as extreme.

Web servers running Windows NT might crash more often than normal, but that was about as bad as it got. Compared to the woes experienced by Windows users, that's not so bad. Microsoft released software patches that addressed the security vulnerability in Windows and Windows NT. Once patched, the original worms could no longer infect a Windows machine; however, the patch didn't remove viruses from infected computers -- victims had to do that themselves.

What should you do if you find out your computer has been hit with a computer virus? That depends on the virus. Many antivirus programs are able to remove viruses from an infected system. But if the virus has damaged some of your files or data, you'll need to restore from backups. It's very important to back up your information often.

And with viruses like the Code Red worms, it's a good idea to completely reformat the hard drive and start fresh. Some worms allow other malicious software to load onto your machine, and a simple antivirus sweep might not catch them all.

Another virus to hit the Internet in was the Nimda which is admin spelled backwards worm. Nimda spread through the Internet rapidly, becoming the fastest propagating computer virus at that time.

The Nimda worm's primary targets were Internet servers. While it could infect a home PCits real purpose was to bring Internet traffic to a crawl. It could travel through the Internet using multiple methods, including e-mail. This helped spread the virus across multiple servers in record time. The Nimda worm created a backdoor into the victim's operating system. It allowed the person behind the attack to access the same level of functions as whatever account was logged into engineer ruler how to read it machine currently.

In other words, if a user with limited privileges activated the worm on a computerthe attacker would also have limited access to the computer's functions. On the other hand, if the victim was the administrator for the machine, the attacker would have full control.

The spread of the Nimda virus caused some network systems to crash as more of the system's resources became fodder for the worm. In effect, the Nimda worm became a distributed denial of service DDoS attack. Not all computer viruses focus on computers. Some target other electronic devices. Here's just a small sample of some highly portable viruses:. Next, we'll take a look at a virus that affected major networks, including airline computers and bank ATMs.

Although the term computer architecture sounds very complicated, its definition is easier than one might think.

Computer architecture is a science or a set of rules stating how computer software and hardware are joined together and interact to make a computer work. It not only determines how the computer works but also of which technologies the computer is capable. Computers continue to be a major part of our lives, and computer architects continue to develop new and better programs and technologies.

Computer architecture is a specification describing how hardware and software technologies interact to create a computer platform or system. When we think of the word architecture, we think of building a house or a building. Keeping that same principle in mind, computer architecture involves building a computer and all that goes into a computer system.

Computer architecture consists of three main categories. All these parts go together in a certain order and must be developed in a pattern so they will function correctly. The best programs for aspiring computer architects are computer-based fields because they offer students the most hands-on experience in database design or network security, both of which are important for computer architects. These classes also teach the students various technologies used in different networks. The advantage of this program is that it offers both computer-related and business courses.

Even after earning the degree, applicants may be required to have at least five years of experience working with IT systems before being hired as a computer architect. As long as we have computers and all the parts that go into a computer system, there will continue to be a demand for computer architects.

While cloud computing has decreased the need for computer architects somewhat, they will continue to be in demand as businesses continue to increase their technology needs. With computers being more technology-based, computer architecture will continue to be an interesting career for candidates interested in developing these machines.
