Protocol | Communication Standard and Layered Approach - Protocols in the OSI Model - Few key points about protocols
What is protocol? In the context of computers and networking, a protocol is a set of rules or conventions that define how data is transmitted and received over a network. It serves as a standard that allows different computer systems to communicate with each other. Protocols are essential for ensuring that data is transferred accurately and efficiently between devices. Here are a few key points about protocols: 1. Communication Standard: Protocols act as communication standards, specifying how data should be formatted, transmitted, received, and acknowledged. 2. Layered Approach: In networking, protocols are often organized in layers. This is known as the OSI (Open Systems Interconnection) model or the TCP/IP (Transmission Control Protocol/Internet Protocol) model. Each layer is responsible for specific aspects of communication. 3. Common Protocols: Examples of network protocols include: HTTP (Hypertext Transfer Protocol): Used for transferring hypertext (web pages) on ...
