Question

Describe the four abstract layers of TCP/IP

Answer 1

The four abstract layers of the TCP/IP are as follows;

1. Application Layer: It provides definitions of protocols for file, mail and hypertext transfer. It also handles the encoding of data, controls the sessions, and defines services and other utilities over TCP/IP.
2. Transport Layer: It provides connection establishment and communication services. It also defines protocols for end-to-end transfer of data, along with error and flow controls. In the TCP/IP model, there are two transport layer protocols namely; TCP and UDP.
3. Internet Layer: It provides addressing and routing services. It also controls congestion on the network. It is also involved in transferring data from a source to a destination network when multiple networks are connected together.
4. Network Interface Layer: It provides addressing and routing services. It also controls congestion on the network. It is also involved in transferring data from a source to a destination network when multiple networks are connected together.
