Etymology

First recorded in 1985–90; bot 1 def. 2 first recorded in 1965–70; shortening of robot

Origin of bot2

First recorded in 1425–75; late Middle English; akin to Dutch bot, Frisian dialect botten (plural); further origin unknown

Origin of bot3

First recorded in 1915–20; perhaps shortening of botfly

Explanation

A bot is a computer program that imitates human activity online. Bots are especially good at doing repetitive tasks very quickly — much faster than a person possibly could. The word bot is shorthand for robot, and it can describe independently moving machines that perform tasks, like the bot vacuum cleaner that terrifies your cat. Online bots have also been programmed to do boring jobs, like mining data from the web or answering basic customer service questions. Most bots are benign (or even useful), but some are malicious, programmed to spread disinformation, spam, and computer viruses.
