COMPUTER WORMS Meaning and
Definition
-
Computer worms are malicious software programs designed to replicate and spread independently within computer networks, often without the user's knowledge or consent. Unlike viruses, which attach themselves to existing files or programs, worms do not require a host file and can operate on their own. These self-contained programs have the capability to propagate across networks, substantially slowing down systems and causing serious disruptions to computer operations.
Computer worms exploit vulnerabilities in computer software and networks to enter a system, often exploiting security loopholes, weak passwords, or unsuspecting users. Once inside, they can rapidly spread from one device to another, using various techniques such as email attachments, malicious links, shared files, or even network connections. Worms can infect multiple computers within a network, creating a chain reaction that can affect a large number of systems within a short period.
The impact of computer worms can range from relatively harmless to highly destructive. While some worms may simply consume network bandwidth or degrade system performance, others can delete files, modify data, or even create backdoors for remote attackers to gain unauthorized access. In addition to their destructive nature, worms can also be used as a means to deliver other malicious payloads, such as ransomware or spyware, further compromising system security.
To protect against computer worms, it is crucial to maintain up-to-date antivirus software, install security patches and updates regularly, employ strong and unique passwords, exercise caution when opening email attachments or clicking on suspicious links, and implement robust network security measures.

Etymology of COMPUTER WORMS
The term "computer worm" originated from the field of computer science. The word "worm" itself has a long history and typically refers to a small, elongated, legless creature. In the context of computer science, a worm is a self-replicating computer program that can spread across computer networks and systems.
The term "computer worm" was first used in the early 1970s by American computer scientist John Shoch and his colleague Jon Hupp at Xerox PARC (Palo Alto Research Center). They developed an experimental program called "Worm" that could move between computers, similar to a biological worm moving from one host to another. It wrote itself onto tapes and would initiate reproduction on other machines.
The choice of the term "worm" was likely due to the similarities between the self-replicating nature of the program and how a real worm reproduces.
