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 ... 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 ... The Open Systems Interconnection (OSI) model —also called the OSI reference model —is a conceptual model that divides network communication and interoperability into seven abstract layers. It provides a standardized model that enables different applications, computer systems and networks to communicate. The OSI (Open Systems Interconnection) model is developed by the International Standard Organization. It is a layered framework for the design of network systems that allows communication between all types of computer systems. Its primary purpose is to provide a set of structural guidelines for exch
