How Does It Work?

The Internet is based on TCP/IP protocol and the packet-switching technology. Transmission control protocol (TCP) is responsible for breaking up messages into sequences of packets, each approximately 1500 bytes. It makes and breaks the connection between computers on the Internet, whereas the Internet Protocol (IP) takes care of routing the data packets on the Internet. At the destination, the TCP software reassembles these packets into complete messages.
