What is TCP/IP-History of TCP/IP, And How does TCP-IP work?

August 13, 2022

The Internet is a very powerful tool that helps to connect millions of people across the globe. the Internet is a global system of interconnected computer networks that use the Internet Protocol (IP) as the network layer protocol.

The TCP/IP (Transmission Control Protocol/Internet Protocol) is a suite of protocols used for communication over the Internet.

TCP/IP protocols are the fundamental building blocks of the Internet. The TCP/IP is a connectionless, best-effort, and unreliable networking protocol suite that runs on top of the Internet Protocol (IP) network layer.

TCP/IP defines two essential protocols: the Transmission Control Protocol (TCP) and the Internet Protocol (IP). TCP/IP is a core set of protocols in the Internet protocols suite.

TCP/IP defines the rules and conventions of the Transmission Control Protocol (TCP), the User Datagram Protocol (UDP), the Internet Control Message Protocol (ICMP), and the addressing and routing protocols. It also provides a common architecture for computers and devices to communicate over the Internet.

In short, the TCP/IP is a standard set of protocols and the most widely used protocol on the Internet. And if you are wondering what is the difference between IP and TCP.

IP (Internet Protocol)

Internet Protocol (IP) is the network layer protocol. It provides the services required for delivering datagrams, including datagram encapsulation and de-encapsulation, fragmentation and reassembly, datagram sequencing, and flow control.

TCP (Transmission Control Protocol)

The Transmission Control Protocol (TCP) is a transport layer protocol that ensures the reliable exchange of information between a host and its environment. It provides full-duplex, sequential, connection-oriented, reliable, and error-free data transmission. The TCP is a component of the TCP/IP suite of protocols and is used in the client-server model of computing.

History of TCP/IP

The TCP/IP model was developed in 1970 by the defense advanced research projects agency (DARPA) which was the branch of the research department of U. S. It is invented by two scientists Vint Cerf and Bob Khan, who was working on the data communication.

Four layers of the TCP/IP model

TCP/IP is divided into four layers, which include the specific protocol or rules. All layers work collectively for the transfer of data from one layer to another.

  • Application layer
  • Transport layer
  • Internet layer
  • Network Access layer

How does TCP-IP work?

TCP-IP is a technology that is used to share information between computers. The Internet is built using TCP-IP. It is the basic communication technology of the Internet.

The Internet uses IP addresses and IP protocols to transfer data between the servers and the end user. The IP is nothing but the unique identifier of the device. Every device that is connected to the internet has its own IP address.
