OSI Model - 3
Open System Interconnection (OSI) Model - 3 Summary on What we have studied in last tutorial :- The data unit at Network layer is known as packet. Network layer receives data from transport layer. It adds header to the data and passes data to the data link layer. The data link layer provides physical addressing which is useful for a local network. Routing is a process wherein a proper path is defined for the packets to reach destination. Internetworking means connecting two or more computer networks together. The data unit at Transport layer is called Segment. Transport layer receives data from the session layer. It divides the data into segment with each segment having its own header and passes these segments to the network layer. (1.5) Session Layer :- This is fifth layer of OSI Model. This layer establishes, manages, synchronizes and terminates connection between the comp...
