What are the 7 layers defined by OSI model of networking?
Based on this, the OSI model defines 7 layers for the transmission of data across the network. These seven layers are: 1) The Physical Layer 2) The Data Link layer 3) The Network Layer 4) The Transport layer 5) The Session Layer 6) The Presentation Layer 7) The Application layer What are the functions of each of the 7 layers of the OSI model? 1) The Physical Layer: The physical layer defines the electrical and physical specifications for devices. In particular, it defines the relationship between a device and a transmission medium such as a copper and optical fiber. The major functions of the Physical Layer are: • Establishment and termination of a connection to a communications medium. • Participation in the process whereby the communication resources are effectively shared among multiple users. For example, contention resolution and flow control. • Modulation, or conversion between the representation of digital data in user equipment and the corresponding signals transmitted over a c
