ABSTRACT
Teleprocessing is simply the exchange of information between computers or other processing equipment across a communications link or telecommunications network. Teleprocessing uses allow a decentralized operation, information retrieval, archiving or storage of information, duplication at several locations or long distance photocopying, and more. Teleprocessing is also used to integrate work functions, decisions, and data files. A main component of teleprocessing systems is computers, which can be mainframe computers, minicomputers, or microprocessors. The computers can operate programs which are considered main programs, preprocesses, or post-processes. Components used in teleprocessing include input devices, such as our depth gauge or flow transmitter, output devices, such as our flood gate control, and transmission and switching facilities. The three common methods for controlling a CPU are through issuing commands such as the REMOTE command, selecting items from a menu, and pointing at pictures on the screen with a pointing device such as a light pen or so-called mouse.
