Solution

The correct option is B Application adaptation

Application adaptation layer in ATM protocol formats the data received from other networks.

ATM stands for Asynchronous Transfer mode. It is a stream line packet transfer interface that makes the use of fixed size packet called cells.It results in an efficient method for transmission over high speed network. It also known as cell relay. It is a connection oriented network.

Asynchronous transfer mode (ATM) is a switching technique used by telecommunication networks that uses asynchronous time-division multiplexing to encode data into small, fixed-sized cells.

Asynchronous transfer mode. ... ATM provides functionality that is similar to both circuit switching and packet switching networks: ATM uses asynchronous time-division multiplexing, and encodes data into small, fixed-sized packets (ISO-OSI frames) called cells.

ATM REFERENCE MODEL: The ATM architecture uses a logical model to describe the functionality that it supports. ATM functionality corresponds to the physical layer and part of the data link layer of the OSI reference model.
