Front End Processor (FEP) A front end processor (FEP), or a communications processor , is a small-sized computer which interfaces to the host computer a number of networks , such as SNA , or a number of peripheral devices , such as terminals , disk units , printers and tape units . Data is transferred between the host computer and the front end processor using a high-speed parallel interface . The front end processor communicates with peripheral devices using slower serial interfaces , usually also through communication networks. The purpose is to off-load from the host computer the work of managing the peripheral devices, transmitting and receiving messages, packet assembly and disassembly, error detection, and error correction. [1] Two examples are the IBM 3705 Communications Controller and the Burroughs Data Communications Processor.
