  1. Long Area Network

  2. Long Area Node

  3. Local Area Network

  4. Local Area Node

  5. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

LAN stands for Local Area Network, a computer network that interconnects computers within a limited area such as a residence or office building.

Multiple choice

Frame relay operates in the

  1. physical layer

  2. data link layer

  3. physical layer and data link layer

  4. network layer

  5. physical layer, data link layer and network layer
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

This is the correct option because frame relay operates in both the physical layer and the data link layer.

Multiple choice

Which of the following methods is used for a dedicated communication path between two devices through one or more intermediate switching nodes?

  1. Packet switching

  2. Circuit switching

  3. Message switching

  4. Banyan switch

  5. None of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

This is the correct option. In circuit switching, a dedicated physical connection is established between the sending and receiving device. Before starting communication, the station must make a reservation of resources to be used during the communication. These resources remain dedicated during the entire duration of data transfer.

Multiple choice

An error detecting code, inserted as a field in a block of data to be transmitted, is known as

  1. frame check sequence

  2. checksum

  3. flow control

  4. frame bursting

  5. fourier analysis
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

This is the correct option. Frame check sequence (FCS) refers to the extra bits and characters added to data packets for error detection and control. FCS technology is one of the best error control techniques and remains popular because of its simplicity.
