What is the difference between a virus and a worm ccna

Worms don't need a host and exploit the vulnerability of a network to spread. Viruses destroy, damage, or alter the files in the infected computer. Worms don't affect the file but increase the resource usage to crash the system or network. Virus spreading speed is low compared to worms The main difference between a computer worm and a computer virus is that worms can spread independently, without being attached to a host file or program. Some people describe computer worms as a subset of computer viruses, but it's more common to consider worms and viruses as two subcategories of malicious software (malware)

Computer Worm vs. Virus: Differences & Similarities AV

  1. Worms is similar to virus but it does not modify the program. It replicate itself more and more to cause slow down the computer system. Worms can be controlled by remote. The main objective of worms to eat the system resources
  2. 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
  3. • Computer worms can be remotely controlled while the viruses are independent. • The viruses infect the files in the computer while worms consume the resources excessively such as the bandwidth and make the system slow and unstable by replicating and running the programs in memory. • Viruses are slower than computer worms
  4. So, the virus, worm and trojan horse come under the category of malicious software. The prior difference between virus, worm and trojan horse is that a virus attaches itself to a program and propagates copies of itself to other programs followed by a human action, while the worm is a solitary program that spreads its copies to other components without modifying it
  5. These types of programs are able to self-replicate and can spread copies of themselves, which might even be modified copies. To be classified as a virus or worm, malware must have the ability to propagate. The difference is that a worm operates more or less independently of other files, whereas a virus depends on a host program to spread itself
  6. Virus replicates itself. Worms are also replicates itself. But Trojan horse does not replicate itself. Virus can't be controlled by remote. Worms can be controlled by remote. Like worms, Trojan horse can also be controlled by remote. Spreading rate of viruses are moderate. While spreading rate of worms are faster than virus and Trojan horse
