The physical layer of the OSI model is not foundational to any of the other layers. True or False

False.

Explanation:

OSI model stands for Open Systems Interconnection. The seven layers of OSI model architecture starts from the Hardware Layers (Layers in Hardware Systems) to Software Layers (Layers in Software Systems) and includes the following;

1. Physical Layer

2. Data link Layer

3. Network Layer

4. Transport Layer

5. Session Layer

6. Presentation Layer

7. Application Layer

Each layer has its unique functionality which is responsible for the proper functioning of the communication services.

The physical layer of the OSI model is the first layer of the OSI model and it is foundational to any of the other layers because it determines the means of transmitting (sending) raw bits from one network node to another and the electrical specification of network equipments.
