7 layers of OSI

Question

7 layers of OSI

Accepted Answer

The OSI model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven abstraction layers.

Physical Layer: Deals with physical connections and signals (e.g. Ethernet cables)
Data Link Layer: Manages data transfer between devices on the same network (e.g. MAC addresses)
Network Layer: Handles routing and forwarding of data packets (e.g. IP addresses)
Transport Layer: Provides end-to-end communication between devices (e.g. TCP)
Session Layer: Manages sessions between applications (e.g. establishing, maintaining, and terminating connections)
Presentation Layer: Translates data into a format that the application layer can understand (e.g. encryption)
Application Layer: Provides interfaces for applications to access network services (e.g. HTTP)
