A device that enables you to communicate with a computer. Generally, a terminal is a combination of keyboard and display screen. Terminals are sometimes divided into three classes based on how much processing power they contain:


1)   Intelligent terminal: A stand-alone device that contains main memory and a CPU.

2)  Smart terminal: Contains some processing power, but not as much as an intelligent terminal.

3)   Dumb terminal: Has no processing capabilities. It relies entirely on the computer's processor.


(B) In networking, a terminal is a personal computer or workstation connected to a mainframe. The personal computer usually runs terminal emulation software that makes the mainframe think it is like any other mainframe terminal.
