What do viruses and worms do in the context of computer networks?

Viruses and worms are types of malware that specifically exploit vulnerabilities within computer networks to propagate themselves. The key characteristic that defines both of these malicious entities is their ability to replicate and spread across systems.

Viruses attach themselves to legitimate programs or files, executing their payload when the infected program runs. This action can compromise system integrity or data integrity, allowing them to spread further to other devices and networks when the infected files are shared or transferred.

Worms, on the other hand, are standalone malware that do not require a host file to propagate. They self-replicate and can spread through network connections, exploiting vulnerabilities to infect new systems without any user intervention. This capability can lead to rapid and uncontrolled dissemination across a network, potentially causing significant disruptions and resource depletion.

The correct response highlights this essential ability of viruses and worms to multiply and spread within networks, which is a critical concept in understanding network security threats and the importance of protective measures in IT environments.
