TCP/IP Application Layer

To be brief, the application layer provides an interface between software running on a computer and the network itself. The application layer does not define the application itself, but rather defines services that applications need. TCP/IP application layer protocols provide services to the application software running on a computer.

In the present situation, Web browser can be considered as one of the TCP/IP application.

What happens to allow web page to appear on browser?

TCP/IP Protocol Architecture

The basic aim of this blog is to provide information on how computers can communicate with each other. TCP/IP defines a large collection of protocols that allow computers to communicate.

Let us now go through the Layers that are established in TCP/IP Architecture.

1. Application Layer eg: HTTP, POP3 (protocols)
2. Transport Layer eg: TCP, UDP
3. Internet eg: IP
4. Network Access eg: Ethernet, Frame Relay
