Bot

A bot is a computer program which acts automatically. It may do things that a person wouldn't normally do, or take a long time to do. It is an automated or semi-automated tool or script. They may be simple, or advanced and complex:

1. Software agents acts for a user doing things which the user programs it for.^[1] Software agents which interact with people (such as chatbots) have features which make this possible, such as natural language processing.
2. More advanced agents:
   1. Intelligent agents can use artificial intelligence.
   2. Autonomous agents change the way they do things to achieve the same objectives. Also, there are multi-agent systems which can work together to get a result which could not be done by a single agent.
   3. Mobile agents can move (relocate) their working to different processors.
