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.
Front end processors are used as network processors.
In time sharing system front end processors are used.
Option B is the Correct Answer.
