Question

The layer of the OSI model where the Media Access Control or MAC, addressing is defined.

a. Physical Layer
b. Data Link Layer
c. Transport Layer
d. Network Layer

Answer 1

MAC addressing occurs at the Data Link Layer of the OSI model, which is responsible for node-to-node data transfer and handling of errors, frame synchronization, and flow control.

Step-by-step explanation:

The Media Access Control or MAC addressing is defined in the Data Link Layer of the OSI model. The Data Link Layer is responsible for node-to-node data transfer and handles error checking, frame synchronization, and flow control. MAC addresses are unique identifiers assigned to network interfaces for communications at the data link layer of a network segment.
