The TCP part is all about ensuring that data is transmitted correctly between two computers. If any errors occur these are
detected and the data is retransmitted. The data transmitted is split up into small portions called data packets. The IP part
of TCP/IP is how these data packets are moved from one point to another. Each computer on the Internet has a unique IP
address and the data packets are moved from the source to the destination through many different computers which is
controlled via TCP/IP. This protocol is used on the Internet and also by computers which are part of a LAN.
