COMPUTER
PROTOCOLS
We all follow conventions in our everyday life when we
communicate, for example, we usually say ‘hello’
and identify ourselves on the telephone before we start
chatting. Exactly the same happens when computers 'talk'
to each other. A set of rules has to be followed - otherwise
total confusion ensues. If all of the computers stick
to the rules, there’s no misunderstanding and information
can be passed on successfully.
These rules
are called protocols. Computing
networks connect computers and other devices, such
as printers, but it’s the protocols that allow
the different devices to talk to one another. Computer
protocols control the exchange of information, the speed,
format, content and reliability of the network.
Protocols - their creation and documentation
Protocols have been developed to a specific technical
standard to which all manufacturers and programmers
conform. In the early days of networking, these standards
were worked out by a group of researchers, called the
Network Working Group (NWG), employed by the US Department
of Defence.
