What is the relationship between Services and Protocols ?
Computers that are connected to each other create a network. Each Computer has its own configuration for Example a computer at MIT may be configured in a compleatly different fashion than a computer at IIT Delhi. If we wish to connect these two computers then we need some comman set of Instructions that can connect these two computers.
This comman set of Instructions is a Protocol. Protocols are fundamental for providing the Internet service and form the basis of all connections and Networking.
