What is Network protocol ?

Protocol is a kind of "set of rules", which are used in digital communication. It is decided by these that how data will be transmitted and received on Computer Network. Protocol in computing is also called digital language. Without these, we cannot communicate with each other on the internet, nor can we transfer data. Any file or mail sent on the Internet works according to this internet protocol. Network protocols are made for the systematic and safe transfer of data on the network. Through these control the data flow rate, data type, process nature and device management process. Thank u.
