COMPUTER NETWORKING

Detailed explanation-1: -A worm is a self-replicating program that is harmful to networks. A worm uses the network to duplicate its code to the hosts on a network, often without any user intervention. It is different from a virus because a worm does not need to attach to a program to infect a host.

Detailed explanation-2: -A computer worm is a self-replicating program that spreads through networks and exploits vulnerabilities in software or operating systems. Unlike viruses, worms do not require human intervention to propagate and can cause widespread damage by consuming system resources or disrupting network traffic.

Detailed explanation-3: -A Worm is a self-replicating program. It is self-contained and does not require a host program. The program creates the copy and causes it to execute; no user intervention is required. Worms commonly utilize network services to propagate to other computer systems [19].

Detailed explanation-4: -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.
