Protocols use a specific model for their implementation like the OSI (Open System Interface) Model, TCP/IP (Transmission Control Protocol / Internet Protocol) Model, etc. All network end-users rely on network protocols for connectivity. Support for network protocols can be built into the software, hardware, or both. The ARPA (Advanced Research Project Agency) part of the US Defense program was the first organization to introduce the concept of a standardized protocol. Protocols are developed by industry-wide organizations. Hence, protocols provide a common language for network devices participating in data communication. Similarly, two hosts implementing the same protocol can connect and communicate easily with each other. If two people share the same language, they can communicate very easily and effectively. Protocols have their own rules, specifications, and implementations. Every language has its own rules and vocabulary. In simple terms, a protocol is similar to a language. It specifies what type of data can be transmitted, what commands are used to send and receive data, and how data transfers are confirmed. It can also be defined as a communication standard followed by the two key parties(sender and receiver) in a computer network to communicate with each other. They are a set of rules that determines how the data will be transmitted over the network.

Protocols are a fundamental aspect of digital communication as they dictate how to format, transmit and receive data. So, let's get started with the basics of protocols. We'll further focus on the types, key elements, and functionalities of protocols. But in this blog, weвЂ™ll mainly concentrate on the protocols used in computer networks and data communication. Protocols are needed in every field like society, science & technology, Data Communication, media, etc. Protocols provide us with a medium and set of rules to establish communication between different devices for the exchange of data and other services. Hence, to resolve this problem, we need protocols. Due to this, they are unable to establish a connection and communicate with each other for sharing data and other information.

They may have been developed using different hardware and software resources. These devices are designed and manufactured by different manufacturers. Billions of electronic devices and gadgets are operating to make this happen. In the era of Computer and Mobile technologies, computer network technology is growing at a very fast speed and frequency.
