A front-end processor (FEP) is a type of computer used in a network to help the main host computer manage the other connected computers. The primary reason for using a front-end processor is to keep the main computer from having to perform all the processing, which requires a lot of computer resources. Depending on the number of nodes to which the FEP can connect, the FEP may have relatively common hardware or very strong hardware. To help administrators with security, these computers often can eavesdrop on data transmissions.

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.

You Explained it very well. Thanks @Mittu Sharma.

Please explain the answer in detail.

Explain this please?
