Question

discuss protocols run on each layer of tcp/ip.

Expert Solution

TCP/IP Protocols:

TCP/IP functionality is divided into four layers, each of which includes specific protocols:

The application layer:

The application layer provides applications with a standardized data exchange.
Its protocols include HTTP, FTP, Post Office Protocol 3 (POP3), Simple Mail Transfer Protocol (SMTP), and Simple Network Management Protocol (SNMP).
At the application layer, the payload is the actual application data.

The transport layer

The transport layer is responsible for maintaining end-to-end communications across the network.
TCP handles communications between hosts and provides flow control, multiplexing, and reliability.
The transport protocols include TCP and User Datagram Protocol (UDP), which is sometimes used instead of TCP for particular purposes.
