The full form of TCP/IP is transmission control protocol/internet protocol.The technical defination is TCP/IP is large family of protocols used to organize computers and communication devices into a network.
The two most imp protocols are TCP and IP.Ip transmits the data from place to place while TCP makes sure it works correctly
Within the internet information is not transmitted as a constant stream from host to host.Rather data is broken into small packages called PACKETS.Eg.You send a mail message to a friend on the other side of the world.TCP will divide the message into a number of packets.Each packet is marked with a sequence number , the address of a recipient, and the address of the sender.In addition TCP inserts some error control information.
The packets are then send over the network, where it is the job of the ip to transport them to the remote host.At the other end TCP receives the packets and check for errors.If an error has occured TCP can ask for that particular packet to be resent.Once all packets are received correctly TCP will use the sequence no to reconstrluct the original message.
The job of IP is to get raw data ---The packets---from one place to another.Hence, the job of TCP is to manage the flow and ensure the data is correct.
