Osi model in computer network: What is OSI Model

What is OSI Model ? OSI or Open System Interconnection model was developed by International Standards Organization (ISO), which allows different communication systems to communicate via standard protocols. It gives a layered networking framework that conceptualizes how communications should be done between heterogeneous systems. In layman's terms, the OSI establishes a standard for computer systems to communicate with one another. The model divides the flow of data in a communication system ... Learn the 7 layers of the OSI Model in computer networks . Understand how each layer works and why the OSI Reference Model is essential in networking . The OSI model has 7 layers, providing a detailed and theoretical framework for how data moves through a network , while the TCP/IP model has 4 layers and is a practical model used on the internet. OSI separates functions more specifically into layers, while TCP/IP combines some layers for simplicity. OSI is mostly used for teaching, and TCP/IP is used in real-world networks , particularly for internet communication. While OSI is protocol-independent, TCP/IP is designed around specific ...
