1.1.6. Unit-Summary

The Internet is a worldwide system of interconnected computer networks. It is used for the communication and the exchange of data between the interconnected computers. The communication between the computers in the Internet is defined by different protocols. The protocols TCP (Transmission Control Protocol) and IP (Internet Protocol) build the basis of this communication.

TCP is a protocol used along with the Internet Protocol (IP) to send data in the form of packets between computers over the Internet. Whereas IP handles the actual delivery of the data, TCP keeps track of the packets that a message is divided into for efficient routing through the Internet.
