FUNDAMENTALS OF COMPUTER

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: -Definition: A computer worm is a malicious, self-replicating software program (popularly termed as ‘malware’) which affects the functions of software and hardware programs. Description: It fits the description of a computer virus in many ways. For example, it can also self-replicate itself and spread across networks.

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.

Detailed explanation-5: -A computer worm is a subset of the Trojan horse malware that can propagate or self-replicate from one computer to another without human activation after breaching a system. Typically, a worm spreads across a network through your Internet or LAN (Local Area Network) connection.
