The Open Systems Interconnection ( OSI ) model is a conceptual framework that divides network communications functions into seven layers . Sending data over a network is complex because various hardware and software technologies must work cohesively across geographical and political boundaries. The OSI data model provides a universal language for computer networking, so diverse technologies can communicate using standard protocols or rules of communication. Every technology in a specific layer ... The OSI model (Open Systems Interconnection model) is a seven- layer conceptual reference model for computer networking and communications. Learn about the seven layers . What are the OSI layers and their functions in the computer network? Explanation in detail about each OSI layer from application to physical architecture. 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.
