Techopedia Explains Bot

In gaming, a bot is a character controlled by a computer. In one sense, bots are all the non-player characters (NPCs) in a game, including those that fight alongside as well as against the gamer. However, the definition of bots has broadened to include gamers who employ third-party programs to control their characters.
