Question

The ISO – OSI model is an 8-layer architecture. (True/False)

Hint:

Remember, the OSI model consists of 7 layers, not 8.

Answer 1

The ISO – OSI (International Organization for Standardization – Open Systems Interconnection) model is a conceptual framework comprising seven, not eight, distinct layers for understanding and implementing network protocols. These layers are:

1. Physical Layer
2. Data Link Layer
3. Network Layer
4. Transport Layer
5. Session Layer
6. Presentation Layer
7. Application Layer

Each layer performs a specific function and interfaces with adjacent layers. The 7-layer OSI model standardizes network communication and promotes interoperability.
