An automated software program that can execute certain commands
when it receives a specific input (like a ro-"bot"). Bots are most
often seen at work in the Internet-related areas of online chat and
Web searching. The online chat bots do things like greet people
when they enter a chat room, and advertise Web sites.
A relatively small and focused computer application that (a) runs
continuously, in the background (i.e., simultaneously), as other
programs are being run, and (b) responds automatically to a user's
activity.
