TCP/IP
TCP/IP stands for Transmission Control Protocol/Internet Protocol. It is quite simply
a standard set of protocols that govern the basic workings of the Internet that was
implemented in 1982.
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.
