Protocols |
|
A protocol
is a set of rules for transmitting
data across a network.
Computers would not be able to communicate if there was no protocol
as they would not be able to interpret each other's transmitted data.
Protocols will have rules for...
- detecting a connection
- handshaking
- how to start and end a message
- how to format a message
- what to do about errors
- how to detect a loss of connection and
what to do next
- terminating a connection
TCP/IP is the basic communication
protocol of the Internet and other networks.

between a client and a server on the Internet. It is also used on

FTP (File Transfer Protocol) is used
for transferring files from one
computer to another. Eg. Uploading web page files to a web server.
