Answer:

The self-replicating program, similar to a virus, taken from the 1970s science fiction novel "The Shockwave Rider" by John Brunner is known as a "worm."

In the novel, Brunner introduced the concept of a computer program that could autonomously spread itself across computer networks, replicating and potentially causing harm or disruption. This idea of a self-replicating program inspired the term "worm" in the context of computer security.

A worm is a type of malicious software or malware that can replicate itself and spread from one computer to another over a network or through various means of transmission, such as email attachments or file-sharing networks. Unlike viruses, worms do not require a host program to attach themselves to and can independently propagate.

Worms can exploit vulnerabilities in operating systems or network protocols to gain unauthorized access to computers or networks. Once a worm infects a system, it can spread to other connected systems, consuming network resources, causing system slowdowns, or even compromising the security and integrity of the affected systems.
