Network Protocols


Protocol means a set of rules.

Internet protocol defines a set of rules that controls or enables a connection, communication or data transfer between two end points. It can also be defines as the rules goverining the syntax, semantics of communication.


Network also works on some protocols to share and transmit data.


A network protocol is a set of rules which defines the process of communication between several computers connected to the network.

We will discuss about some of the commonly used protocols as listed below:

  1. TCP/IP
  2. HTTP 
  3. FTP
  4. Telnet
  5. UDP
  6. IMAP


TCP/IP stands for Transmission Control Protocol/Internet Protocol.


This network protocol is used in the internet. It can be considered as one of the core protocols of internet protocol suite. TCP/IP protocol ensures reliable delivery of the stream of bytes . This feature makes it suitable for applications suh as File transfer and e-mail. It also manages the large fraction of individual communication between internet hosts, for example, web server and web client.


TCP/IP also controls the rate and size of the message or data that can be exchanged between client and server. It is set of protocols that allows computers to share resources over network.


TCP/IP is an open protocol as it is not tied to any particular hardware or software.

TCP/IP model has four layers. From lowest layer to highest layer these arranged as shown below:

  • The Link layer
  • The Internet layer
  • The Transport layer
  • The Application layer
