Protocol and Standards in Computer Networks
What is a protocol?
A protocol is a set of rules and procedures that is followed by the sender and the receiver in order to make communication successful.
There are different types of protocols used for different types of communication.
What is standard?
Standards refer to a set of rules used for data communication to enable an exchange of information among the devices.
Standards are of two types:
- De Facto Standard
- De Jure Standard
De Facto Standard
De Facto stands for “By fact” or “By convention”. These standards have not been approved by any organization, but are adopted because of their widespread use. Usually, these standards are established by manufacturers.
For example, Apple and Microsoft are two companies, and may have their own set of rules, but might follow the same standards for manufacturing.
De Jure Standard
De Jure stands for “By-law” or “By regulations”.
These standards are approved by established organizations like IEEE, ISO, or ANSI. They are mandatory and are important to be followed.
For example, All the standard protocols like TCP, IP, etc are important to follow for data communication.
