How is a computer virus similar to a biological virus?

Malignant computer programs are often called viruses because they share some of the traits of biological viruses. The computer virus requires a functioning “host machine” to replicate, works only with the proper “host,” and passes from computer to computer like a biological virus passes from person to person.

How are computer viruses similar to biological viruses quizlet?

Computer viruses are similar to biological viruses. This is because like biological viruses, the computer virus infects its host which is the computer server.

Which of the following is a characteristic of a computer virus?

A computer virus performs two basic functions: it copies itself from machine to machine (self- reproducing), and it executes the instructions the perpetrator has planned. A computer virus exhibits three characteristics: a replication mechanism, an activation mechanism, and an objective.

How would you define a computer virus quizlet?

a computer virus is a tiny program that can find it’s way on your computer and cause trouble. It may spread through your computer through an email attachment, internet downloads, cds, and file sharing or anytime your computer recieves data.

Is a computer virus similar to biological virus True or false?

It is False because it share some traits but not all….. Explanation: Computer viruses are called viruses because they share some of the traits of biological viruses. A computer virus passes from computer to computer like a biological virus passes from person to person.

Is computer virus is different from biological virus?

They’re not living organisms at all – they’re just different types of viral replicating materials that have acquired lifelike characteristics by accident.

How might a computer virus infect your computer quizlet?

Almost all viruses are attached to an executable file, which means the virus may exist on your computer but it actually cannot infect your computer unless you run or open the malicious program. A virus must be spread by a human action, (such as running an infected program) to keep it going.

Which of the following is the clearest definition of a computer virus quizlet?

Which of the following is the clearest definition of a computer virus? Code-created malware that, when executed, damages programs and performance.

Is malicious computer code that like its biological counterpart?

A computer virus (virus) is malicious computer code that, like its biological counterpart, reproduces itself on the same computer. Strictly speaking a computer virus replicates itself (or an evolved copy of itself) without any human intervention.

What are two main characteristics of computer viruses?

A computer virus, much like a flu virus, is designed to spread from host to host and has the ability to replicate itself. Similarly, in the same way that flu viruses cannot reproduce without a host cell, computer viruses cannot reproduce and spread without programming such as a file or document.

What are two common characteristics of computer virus?

  • Ongoing crashes and blue screen errors.
  • Slow performance.
  • Missing files.
  • Low storage.
  • Unexpected behavior.
  • Constant browser pop-ups.
  • Unidentifiable programs.
  • Increased network activity.

Which two characteristics describe a computer virus?

So, what is a computer virus – simply put, a computer virus is a malicious code that can copy itself and infect a computer without the approval or knowledge of a user. A computer Virus has two major characteristics, the ability to replicate itself and the ability to attach itself to another computer file.

When a computer is infected by a virus?

If you think your computer has been infected, start by running a full system scan using your antivirus software and an anti-malware program. Review the threats and take any action that you can (the software should guide you through this).

Which type of malware self replicates between computers from one computer to another )?

Worms are a self-replicating type of malware (and a type of virus) that enter networks by exploiting vulnerabilities, moving quickly from one computer to another.

What is an infected robot computer?

Bots and botnets ‘ A bad bot is used by a cybercriminal to take over a computer – even your personal PC. This infected computer is called a zombie. Over a period of time, attackers take over multiple computers and create a network of zombie computers.

Why computer viruses are called viruses?

The concept behind the first malicious computer programs was described years ago in the Computer Recreations column of Scientific American. The metaphor of the “computer virus” was adopted because of the similarity in form, function and consequence with biological viruses that attack the human system.

Which one of the following is not true for a computer virus?

solution: option (b) Malware can only spread through the Internet is the correct answer.

Are viruses biological?

Viruses are by far the most abundant biological entities on Earth and they outnumber all the others put together. They infect all types of cellular life including animals, plants, bacteria and fungi. Different types of viruses can infect only a limited range of hosts and many are species-specific.

Is a computer virus is similar to human virus?

Most human viruses are essentially DNA or RNA code, strands that contain essential genetic instructions for all known living organisms. “In a nutshell: a biological virus is information that codes for behavior in a host system,” the researchers say. Computer viruses are essentially the same.

What is the difference between computer virus and computer worm?

The primary difference between a virus and a worm is that viruses must be triggered by the activation of their host; whereas worms are stand-alone malicious programs that can self-replicate and propagate independently as soon as they have breached the system.

Is a computer virus a living thing?

So were they ever alive? Most biologists say no. Viruses are not made out of cells, they can’t keep themselves in a stable state, they don’t grow, and they can’t make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.

What is the difference between a Trojan and a true virus quizlet?

Unlike viruses, Trojan horses do not replicate themselves but they can be just as destructive. Trojans also open a backdoor entry to your computer which gives malicious users/programs access to your system, allowing confidential and personal information to be theft.

Which statement best describes what happens to the temporary working memory RAM of a computer when it is shut down?

Which statement best describes what happens to the temporary working memory (RAM) of a computer when it is shut down? The data is not saved.

What is a multipartite virus quizlet?

Multipartite Viruses. A multipartite virus (also known as a multipart virus or hybrid virus) combines the approach of file infectors and boot record infectors and attempts to attack both the boot sector and the executable or program files at the same time.

Which of the following is the most accurate definition of virus?

Virus: A microorganism that is smaller than a bacterium that cannot grow or reproduce apart from a living cell. A virus invades living cells and uses their chemical machinery to keep itself alive and to replicate itself.
