Software agent
In computer science, a software agent is a piece of autonomous, or semi-autonomous proactive and reactive, computer software. Many individual communicative software agents may form a multi-agent system.
To be considered an agent, a software object must be a self-contained program that is capable of making independent decisions and taking actions to satisfy internal goals based upon its perceived environment.

- In Unix-style networking servers, httpd is an HTTP daemon which implements the Hyper-Text Transfer Protocol at the root of the World Wide Web
- Management agents used to manage telecom devices
The definition of agent processing can be approached from two interrelated directions:
- internal state processing and ontologies for representing knowledge
- interaction protocols - standards for specifying communication of tasks
Agent systems are used to model real world systems with concurrency or parallel processing.
