Question

Determine which layer(s) of the seven layers of the OSI model has (have) the following functions. List all the layers if more than one layer have the function, e.g. PL (Physical Layer), DL (Data Link Layer), NL (Network Layer), TL (Transport Layer), & AL (Application Layer – OSI layers 5 - 7). (10 points – 1 points for each sub-question)

1. modulation
2. flow controls
3. error detection & error controls
4. multiplexing
5. collision detection
6. addressing
7. end-to-end network packet delivery
8. connection-oriented or connectionless
9. segmentation or streaming
10. end-to-end user data delivery

Answer 1

As per Chegg answering guidelines, I'm answering only the first 4 parts:-

a) modulation - PL(Physical Layer)

b) flow controls - Both TL(Transport Layer) and DL(Data Link Layer)

c) error detection & error control - Both TL(Transport Layer) and DL(Data Link Layer)

d) multiplexing - TL(Transport Layer)

e) collision detection - DL(Data Link Layer)
