II.2.5 Protocols

A protocol is an agreed upon format for transmitting data between two devices. So that packages of data can go of a computer source to a computer of destination on a network, it is important that all the units of the network communicate in the same language or protocol. A protocol consists of a whole of rules which increase the effectiveness of the communications within a network.

They are two types of protocol:

· CONNECTION ORIENTED PROTOCOL:

They are the protocols operating a control of transmission of the data during a communication established between two machines in such a diagram, the receiving machine sends acknowledgements of delivery at the time of the communication, thus the transmitting machine is guarantor of the validity of the data which she sends. The data are thus sent in the form of flood. TCP is a protocol directed connection

· CONNECTIONLESS ORIENTED PROTOCOL

It acts of a mode of communication in which the transmitting machine sends data without preventing the receiving machine, and the receiving machine receives the data without sending notice of receipt to the first. The data are thus sent in the form of blocks (datagram). UDP is a protocol not directed connection
