      What Is a Protocol in Networking?

      The protocol in networking is defined as it is the set of established rules that decide how data is transmitted between the devices on the same network. regardless of any differences in the design, internal structure, and structure, it accesses the devices to communicate with each other. Network protocol plays a very important role in modern digital communication through this people are able to communicate all over the world. The same language is very easy to communicate same is the case with network protocols pre-determined rules help the two devices communicate with each other. Without the usage of network protocols, both WAN (wide area networks) and LAN (local area network) do not work properly.

      Network Protocol Operation:

      Network protocol work in such a way that it breaks the large processor into smaller specific task or functions. This process happens at every level of the network and each function cooperates with each level to complete the larger task. The term protocol refers to smaller network protocols that work in interconnection with each other. Network protocols are created by various information technology and networking organization. some groups are given below that produced the network protocols,

      • IETF (the internet engineering task force)
      • W3C (the world wide web communication)
      • ITU (the international telecommunication union)

      Uses of network protocol:

      Network protocols are not specifically related to  IT professionals and Certified Network Specialists this is used today by billions of people, whether they know it or not. Every time when you use the internet you are influenced by the protocols. Although you did not know how it works and how often you encountered them network protocols are essential for internet and the modern digital communication.

      List of network protocols:

      There are different thousands of protocols but they perform three main primary functions such as,

      • Network management
      • Communication
      • Security

      It is necessary for every device to use the devices safely, and they work together to ease the usage.

      Security:

      It is also called a cryptographic protocol it makes sure that the data sent over are protected from attackers. Common functions are,

      • Encryption
      • Transportation
      • Entity authentication

      Communication:

      It allows communication between devices it is used in both digital and analog communication. It is used for important processes such as transferring files between devices to access the internet.

      Network management:

      It defines the procedures that are needed to operate a computer network effectively. On a single network, it affects various devices including routers, servers, and computers. These functions performed by the network management are,

      • Connection
      • Link aggregation
      • Troubleshooting.
