These acronyms are used to discuss LAN, internet, WAN, routing and switching protocols, and their applicable organizations. [ 1 ] [ 2 ] [ 3 ] The table contains only current, common, non-proprietary initialisms that are specific to information technology.
Computer viruses generally require a host program. [11] The virus writes its own code into the host program. When the program runs, the written virus program is executed first, causing infection and damage. A worm does not need a host program, as it is an independent program or code chunk.
Cohen used the term "computer virus" to describe programs that: "affect other computer programs by modifying them in such a way as to include a (possibly evolved) copy of itself." [ 11 ] (note that a more recent definition of computer virus has been given by the Hungarian security researcher Péter Szőr : "a code that recursively replicates a ...
Hex dump of the Blaster worm, showing a message left for Microsoft co-founder Bill Gates by the worm's programmer. This timeline of computer viruses and worms presents a chronological timeline of noteworthy computer viruses, computer worms, Trojan horses, similar malware, related research and events.
