TCP--Transmission Control Protocol

IP --Internet Protocol

We use internet to receive data or share data such as we use email services to send messages and receive messages. In this communication behind there is a network which transfer our data according to our sender information. In this data transformation process several network layer and protocol works.  Our message goes to our sender through several layer and protocols of network. In this paper, we will discuss about two protocols one is TCP/IP which is most commonly used.

The function of TCP

(1) TCP provides reliable data transfer. Using flow control, sequence numbers,acknowledgments, and timers,TCP ensures that data is delivered from sending process to receiving process,correctly and in order.

(2) TCP  provides congestion control

(3)TCP  strives to give each connection traversing a congested link an equal share of the link bandwidth.

The function of IP

It  like a car driving on a highway, each packet passes through a gateway computer , which serve to forward the packets to the right destination ,each host  has an IP address.
