Computer Networks Questions

Multiple choice

Find the odd one out.

  1. Network

  2. Session

  3. TCP

  4. Transport
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Network, Session, and Transport are layers of the OSI model. TCP is a transport layer protocol, making it the odd one out as it is a protocol, not a layer.

Multiple choice

The fourth layer of OSI model is

  1. transport

  2. session

  3. application

  4. network
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The OSI model layers are: 1 Physical, 2 Data Link, 3 Network, 4 Transport, 5 Session, 6 Presentation, 7 Application. Thus, the fourth layer is the Transport layer.

Multiple choice

The second layer of OSI model is

  1. data link

  2. physical

  3. session

  4. network
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The OSI model layers are: 1 Physical, 2 Data Link, 3 Network, etc. Therefore, the second layer is the Data Link layer.

  2. layer 5

  3. layer 1

  4. none of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Media Access Control (MAC) is a sublayer of the Data Link layer, which is Layer 2 of the OSI model. Since Layer 2 is not listed in the options, 'none of these' is the correct choice.
