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 used to understand and implement network protocols in seven distinct layers, not eight. These seven 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 serves a specific function and communicates with the layers directly above and below it. The 7-layer OSI model helps standardize network communication and interoperability.
