Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Application Layer (Layer 7) of the OSI model provides network services directly to the user and application programs, including file transfer, resource sharing, and management.

Multiple choice

On which layer do bridges recognize the addresses?

  1. 1

  2. 3

  3. 2

  4. All of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Bridges operate in both physical and datalink layers. So, the layer supports a data link layer (layer 2). Bridges work at the Data Link Layer of the OSI model because they work at this layer, all information contained in the higher levels of the OSI model is unavailable to them. Therefore, they do not distinguish between one protocol and another.
