Transmission Control Protocol, or TCP, is one of the many core elements in the Internet Protocol Suite. The Internet Protocol Suite is the set of protocols used to communicate in the Internet and in other networks.

The TCP’s whole suite is widely held as “TCP/IP”. The IP takes care of the lower-level computer-to-computer transmissions. TCP operates at a more intricate level. TCP takes care of only two end systems such as a Web server and browser.

The model of TCP/IP is composed of four layers (starting from the highest):

  1. Application Layer,
  2. Transport Layer,
  3. Internet Layer, and
  4. Link Layer.

How TCP Works

IP works by exchanging packets. A packet is a piece of information composed of a series of bytes and has both a header and a body. The header determines the destination of the packet and the routers where it will pass, while the body holds the data of the IP it is about to transmit. When the IP transmits data as a substitute to TCP, the IP packet body contents are called TCP data.

Advantages of TCP

TCP is efficient in delivering a stream of bytes from one computer to another, even if they are of different programs. TCP is useful in the Web, file transfer and in email transactions. TCP can control message sizes, message exchange rates and network traffic organization.

TCP is also keen in detecting congestion within networks, traffic imbalances, and other inevitable network mishaps. If the TCP detects these, it sends a request for the retransmission of packets that were caught in the crossfire.

It rearranges the packets and reduces the possibility of other network problems, thereby minimizing network congestion. When the TCP at the other end has already rebuilt a perfect replica of the data originally transmitted, it sends this data to its application programs. TCP hastens network communication tasks.

Data Load Delivery by TCP

TCP can efficiently send a large load of data through the Internet using IP. Before, these data were broken down into IP-sized chunks and were requested through a set of IP requests. With TCP, you can send a large amount of data with just a single TCP request which will handle all the IP intricacies.
