They may have been developed using different hardware and software resources. Due to this, they are unable to establish a connection and communicate with each other for sharing data and other information.
Hence, to resolve this problem, we need protocols. Protocols provide us with a medium and set of rules to establish communication between different devices for the exchange of data and other services.
We'll further focus on the types, key elements, and functionalities of protocols. So, let's get started with the basics of protocols. Protocols are a fundamental aspect of digital communication as they dictate how to format, transmit and receive data. They are a set of rules that determines how the data will be transmitted over the network. 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.
It specifies what type of data can be transmitted, what commands are used to send and receive data, and how data transfers are confirmed.
In simple terms, a protocol is similar to a language. Every language has its own rules and vocabulary. Protocols have their own rules, specifications, and implementations. If two people share the same language, they can communicate very easily and effectively. Similarly, two hosts implementing the same protocol can connect and communicate easily with each other.
Hence, protocols provide a common language for network devices participating in data communication. Protocols are developed by industry-wide organizations. Support for network protocols can be built into the software, hardware, or both. All network end-users rely on network protocols for connectivity. The result of their work became what we know today as the Internet. Protocols are simply rules for communication. As applied to humans, protocols typically refer to rules of communication between people of different cultures or people in specific situations.
A violation of a protocol can lead to a breakdown in communication. Something as simple as placing a business card in your pocket may offend your Asian business partner because it violates etiquette, a type of protocol.
Protocols are critical for communications of all types. Computer networks provide a communications path within and between businesses of various types in different locations around the world. Computer networks employ various types of equipment, including routers, switches, hubs and network interface cards.
Network protocols are the reason you can easily communicate with people all over the world, and thus play a critical role in modern digital communications. Neither local area networks LAN nor wide area networks WAN could function the way they do today without the use of network protocols.
Network protocols take large-scale processes and break them down into small, specific tasks or functions. This occurs at every level of the network, and each function must cooperate at each level to complete the larger task at hand. The term protocol suite refers to a set of smaller network protocols working in conjunction with each other.
Network protocols are typically created according to industry standard by various networking or information technology organizations. While network protocol models generally work in similar ways, each protocol is unique and operates in the specific way detailed by the organization that created it. Billions of people use network protocols daily, whether they know it or not.
Every time you use the internet, you leverage network protocols. Though you may not know how network protocols work or how frequently you encounter them, they are necessary for using the internet or digital communications in any capacity.
