The ability and means to communicate with or otherwise interact with a system, to use system resources to handle information, to gain knowledge of the information the system contains, or to control system components and functions.
The ability and means to communicate with or otherwise interact with a system to use system resources either to handle information or to gain knowledge of the information the system contains. (Compare: handle.)
Usage: The definition is intended to include all types of communication with a system, including one-way communication in either direction.

(See: "passive user" under "user".)
