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.
