The OSI (Open Systems Interconnection) model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven abstraction layers. Each layer in the OSI model serves a specific purpose and communicates with the adjacent layers. Here's a brief description of each layer from the bottom (Layer 1) to the top (Layer 7):
- Function: Deals with the physical connection between devices.
- Activities: Transmission and reception of raw bit streams over a physical medium, such as cables or wireless signals.
- Devices: Hubs, cables, repeaters.
