WebFeb 7, 2024 · OSI model is a layered framework that allows communication between all types of the computer system. It has seven layers. OSI model is introduced by ISO (International Organization for Standardization) in 1984. Each layer has its own functionalities and calls upon the services of the layer just below it. WebCommon network protocols and functions are key for communication and connection across the internet. Use this expert advice to learn the differences between the TCP/IP model vs. the OSI model, and explore how they relate to each other in network communications.
