A network protocol is a set of rules and procedures that govern the communication between two or more devices on a network. The role of a network protocol is to ensure that devices can communicate with each other in a standardized and predictable way, regardless of the specific hardware, software, or operating systems they are using.
Some of the key functions of a network protocol include:
- Establishing and maintaining connections between devices
- Defining how data is formatted and transmitted over the network
- Providing error detection and correction mechanisms to ensure data integrity
- Managing network congestion and ensuring that data is transmitted efficiently
- Enforcing security policies and preventing unauthorized access to network resources.
By defining a common language and set of rules for communication, network protocols allow devices to exchange information and collaborate effectively, enabling a wide range of applications and services to be built on top of them.
