Detailed explanation-1: -In the OSI reference model, the communications between a computing system are split into seven different abstraction layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.
Detailed explanation-2: -As mentioned, the model is designed to break down data transmission standards, processes and protocols over a series of seven layers, each of which is responsible for performing specific tasks concerning sending and receiving data.
Detailed explanation-3: -The OSI model has seven layers, as shown in Table 5.1.
Detailed explanation-4: -The data link layer (Layer 2) of the OSI model actually consists of two sublayers: the Media Access Control (MAC) sublayer and the Logical Link Control (LLC) sublayer. The MAC sublayer controls device interaction. The LLC sublayer deals with addressing and multiplexing.
