TCP/IP Full Form - Transmission Control Protocol/Internet Protocol

  • Full Form of TCP/IP stands for Transmission Control Protocol/Internet Protocol. It’s a collection of protocols or rules and procedures that governs communications among computers on the internet.
  • Although the entire internet protocol suite is usually called TCP/IP, it's one in all the core protocols of the web Protocol Suite.
  • It has been developed in 1978 and driven by Vint Cerf and Bob Kahn.
 Transmission Control Protocol

Transmission Control Protocol

  • TCP/IP may be a commonly used standard for transmitting data over networks. In simple words, it's the suite of communication protocols which connect network devices on the web or used to interconnect network devices on the web.
  • It decides how the data are exchanged over the web through end-to-end communications that include how the data should be arranged into packets (bundles of information), addressed, sent, and received at the destination. This communication protocol may be used to interconnect network devices in the private network such an intranet or an extranet.

How TCP/IP works?

  • As the name suggests, TCP/IP comprises two basic protocols: TCP (transmission control protocol) and IP (Internet protocol).
  • TCP :
    • The TCP allows applications to make a channels of communications across a network.
    • It also allows a message to be divided into smaller packets before they're transmitted over the web then assembled in the right manner at the destination address. So, it ensures the reliable transmission of data across the network. Furthermore, it also checks errors in the packets and requests for re-transmission if errors are found.
  • IP :
    • The IP address tells the packets the address and route so they reach the correct destination.
    • It’s a way that enables gateway computers on the internet-connected network forward the message after checking the IPS address.
    • It’s like a line of workers passing coal from a mine to a mining cart.

TCP/IP model layers

TCP/IP, which is a standard layered protocol suite comprises a collection of rules and procedures, is split into four layers, on the premise of their functionality. Each layer has a specific protocol.

 Tcp/Ip Model Layers

Tcp/Ip Model Layers

  • The applying layer : This layer includes all the protocols required to communicate directly with the end-users. Some important protocols in this layer include HTTP (Hypertext Transfer Protocol) , FTP (File Transfer Protocol), SMTP (Simple Mail Transfer Protocol), and the DHCP (Dynamic Host Configuration Protocol).
  • The transport layer : This layer ensures the transmission of the right message or data in proper order. It utilizes UDP (User Datagram Protocol) and TCP.
  • The network access layer : It offers the functionalities to create and handle packets of data.
  • The internet layer : It performs two basic functions, routing and addressing by using IP (Internet Protocol). It tells how the packets are to be sent to the destination.
