What is a network protocol? Why are network protocols necessary?
A network protocol is a set of rules and procedures for defining a particular type
of communication in a network. There are several network protocols depending
on what is expected of the communication.
The network protocols are hierarchized in layers, to break down and order the
different tasks. Some network protocols operate at multiple layers; others may
be specialized in performing a task corresponding to a single layer. There are
several families of protocols or models, each model being a series of protocols
between various layers. Among these models are OSI and TCP/IP models.
Network protocols are the infrastructure that ensures the proper functioning of
the network as they allow the different entities of the network to communicate
and understand each other.
