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.

Examples

• user agent - for browsing the World Wide Web
• mail transfer agent - for serving e-mail
• SNMP agent
• DAML
• daemons in Unix-like systems. See the mascot for BSD systems. CTSS first named daemons; see also Maxwell's demon.
• 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.
