Nowadays we all use the Internet, and the Internet is a network of networks that works on protocols, and TCP IP Protocol is one of the important protocols used over the network, and we at QuesAns are going to explain what is TCP/IP and what is the difference between TCP and IP.

We will talk about both what is tcp/ip i.e. what is TCP and what is IP in computer networks one by one, So let’s start with TCP Protocol first.

What is TCP in computer networks ?

Full form of TCP is Transmission Control Protocol which is a set of protocols (rules) used along with the Internet Protocol (IP) to send data in the form of message units between computers over the Internet. TCP is intended to send packets across networks and make sure the successful transporting of data and messages over networks.

The TCP is known as connection-oriented protocol, which is means that a connection is established and maintained through the whole process until the message or messages to be exchanged by the application program at each end have been exchanged. In short, TCP is a connection-oriented transport protocol that provides reliable, full-duplex data transmission between two entities, often a client and a server application. 

Working of TCP.

Like, when an HTML file is sent to you from a Web Server, the TCP program layer,  in that server divides the file into one or more than one packet, and numbers the packets, and then send each packet to the Internet Protocol program layer. Even though each packet has the same destination IP (Internet Protocol) address, but they might be routed differently through the network.

The TCP arranges all the data which will be transmitted between a server and a client. TCP is responsible for ensuring that a message is divided into the packets that IP manages and for reassembling the packets back into the complete message at the other hand in its original form, while ensuring data integrity is in place throughout the transmission process.

In a result, TCP Protocol is used by all high-level protocols that need to transmit data. TCP is used to send and receive email through Internet Message Access Protocol (IMAP), Post Office Protocol (POP), and Simple Mail Transfer Protocol (SMTP), and for Web access through the Hypertext Transfer Protocol (HTTP). TCP also includes Peer-to -Peer sharing like File Transfer Protocol (FTP).

Upto here you may have been understood what is Tcp/Ip protocol in computer networks. So now after learning about TCP Protocol in what is tcp/ip suite lets learn about what is IP protocol.

What is IP Address?

Now after TCP lets see what is IP Address. The Full Form of IP is Internet Protocol which is a network-layer protocol that contains addressing information and some control information that enables packets to be routed.IP is documented in RFC 791. Along with the Transmission Control Protocol(TCP), IP Address represents the heart of the Internet Protocol.

The Internet Protocol (IP) is the primary network protocol used on the Internet, developed in the 1970s. On the Internet and many other networks, IP is often used together with the Transmission Control Protocol (TCP) and referred to interchangeably as TCP/IP.

IP supports unique addressing for computer on a network. Most networks use the Internet Protocol version 4 (IPv4) standard that features IP address of four bytes (32 bits) in length. The newer Internet Protocol version 6 (IPv6) standard features addresses 16 bytes (128 bits) in length. This is basic information about what is tcp/ip networks.

History of TCP IP:

In the next part of What is TCP/IP module we will be looking at history of TCP IP Networks.

The TCP IP is an Industry-based protocol suite for Wide Area Network (WANs) developed within the 1970s and 1980s by the Department of Defense (DoD) in U.S. The TCP/IP could be a routable protocol that’s suitable for connecting dissimilar systems (like Windows and UNIX) in heterogeneous networks. It’s the protocol of the worldwide network called Internet.

The Internet began as a project funded by the US Department of Defense (DoD) within the 1970s to interconnect educational institutions and government installations. At that point, it had been called ARPANET (Advanced Research Projects Administration Network). Over the time it’s evolved into the large, worldwide network called the web. The protocols that structure the net protocol suite, the simplest known being is the TCP and Ip, became de-factostandards due to the success of the web. The entire protocol suite is observed as “TCP/IP”. 

Difference between TCP and IP?

TCP and IP protocols are two different computer network protocol and are part of what is Tcp/IP protocol.

TCP arranges the data and divides the data into packets, and then reassemble them while IP provides address to packets to reach their destination. But the both Protocols are used together, and there is no point in making difference between TCP/IP. They are often used together as “TCP IP” Protocols and “TCP IP” model which is also known as DoD model.

What is TCP/IP working?

The TCP/IP is a two- layered protocol in what is tcp/ip protocol suite: TCP is the higher level protocol which deconstruct al the message content itno “data packets” and numbers each data packets that should be transmitted over the Internet.While Ip the lower layer protocol manages the data packets and reassembles the data packets. IP provides address to the packets to reach their destination. The packets gets routed through different paths when the first route is busy or congested.

However, the TCP/IP suite protocol is also known as stateless,which consider as each client request is meant to be new because it is not relevant to previous request. Thus, paths are frees up due to being stateless so paths can be used continuously.

So at the end of this article we hope you have cleared your doubt regarding What is TCP/IP in computer networks.
