What is Protocol? Types of Internet Protocols


  • Protocols are set of rules that transfer data from one location to another.
  • Network has many protocols.
  1. o  TCP/IP
  2. o  IEEE 802.X Standard
  3. o IEEE 802.3 and 802.5 Standard o IEEE 802.6 Standard.


  • TCP/IP stands for transmission control protocol/Internet protocols.
  • TCP/IP protocol communicates between two similar or dis-similar computer systems.
  • Very popular protocol in large networks.
  • It is used in Network layer and transport layer.
  • Example are

IEEE 802.X Standard:

  • IEEE stands for Institute of Electrical & Electronics Engineers (IEEE).
  • IEEE has developed a set of standard about cabling, Topology and Access time of network products.
  • The general committee working on these standard is called 802.
  • This standard is used in lower two layers (Physical & Data Link Layer).

IEEE 802.3 and 802.5 Standard:

  • IEEE 802.3 uses carrier sense Multiple Access (CSMA) on bus topology.
  • IEEE 802.6 standard used in Token Ring Topology.

IEEE 802.6 Standard:

IEEE 802.6 use in Metropolitan Area Network (MAN).
