Which of the following is/are the applications of Asynchronous Transfer Mode (ATM)?

Explanation

ATM reference model comprises of three layers Physical Layer In this layer, the cells are converted into bitstreams and transmitted over the physical medium. This layer has two sub-layers: PMD sublayer (Physical Medium Dependent) and TC (Transmission Convergence) sublayer. ATM Layer It accepts the 48-byte segments from the upper layer, adds a 5-byte header to each segment, and converts into 53-byte cells. This layer is responsible for routing of each cell, traffic management, multiplexing and switching. ATM Adaptation Layer It provides facilities to the existing packet-switched networks to connect to the ATM network and use its services. It accepts the data and converts them into fixed-sized segments. This layer has two sub-layers − Convergence sub-layer and Segmentation and Reassembly sub-layer. ATM Applications: ATM WANs Multimedia virtual private networks Frame relay backbone Residential broadband networks Carrier infrastructure for telephone and private line networks Therefore All of the options is the answer
