In the field of computer, VIRUS stands for

Question

UnlockIAS · Accepted Answer

Correct — B, 'Vital Information Resource Under Siege.' This is the popular backronym used for VIRUS in computer-awareness questions. A computer virus is malicious code that attaches itself to a legitimate program or file and replicates whenever that host is executed — the phrase captures the idea that a system's vital information resources are put 'under siege.' The other three options are invented, meaningless word-strings.

Why the other options are wrong — (a) Not a recognised expansion — a made-up string of words with no accepted meaning.  (c) A meaningless coinage; no such definition of VIRUS exists.  (d) Invented — not an accepted full-form of VIRUS.

Concept: A computer virus is self-replicating malicious software (malware) that inserts its code into other programs or files and activates when the infected host is run. The 'full form' Vital Information Resource Under Siege is a mnemonic/backronym — the term 'virus' was itself borrowed from biology because the program spreads by infecting hosts, much like an infectious agent.
