OSI stands for Open Systems Interconnection. It's basically a framework that defines how different devices in a network communicate with each other. Imagine it as a set of rules or guidelines that help ensure smooth communication between computers, routers, and other network devices. It breaks down the communication process into seven layers, each responsible for a specific task like transferring data, error detection, or formatting. Think of it like building a cake, where each layer has its own role and contributes to the final product—in this case, seamless network communication.
