The Open Systems Interconnection model (OSI model) is a product of the Open Systems Interconnection effort at the International Organization for Standardization. It is a way of sub-dividing a communications system into smaller parts called layers. A layer is a collection of co...

Though TCP/IP is more directly applicable to networking,the Open Systems Interconnection (OSI) model—sometimes called the OSI reference model—has also had a substantial impact on computer networking and computer science, writ broadly. OSI is a conceptual model that divides network communication into...
