Computer Networks Questions

Multiple choice

The processing location on a computer network is called

  1. node

  2. switch

  3. router

  4. gateway

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

Nodes or hosts are the processing locations of a computer network as all the data transmitted or received by the network are analysed and processed at these places only.

Multiple choice

Which of the following is incorrect?

  1. Clients can store data.

  2. LAN is faster as compared to MAN.

  3. Servers have more storage power than PCs.

  4. Peer to peer communication is safe.

  5. MICR is used in CBS.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Peer to peer network has no central authority to determine security features as well as sharing features for users. Any user can modify the data as per his/her wish. So, it is not very safe.

Multiple choice

The most reliable network is

  1. WAN

  2. MAN

  3. LAN

  4. WLAN

  5. SAN
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

LAN is sized up to few kilometers. The transmission time in worst case is known in advance using the length. Hence, it is more reliable as compared to others.

Multiple choice

Which of the following network cables given below supports higher bandwidth for high transmission speeds in a computer network?

  1. Twisted pair cable

  2. Coaxial cable

  3. Optical fiber cable

  4. Copper cable

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

The maximum bandwidth's supported by different cables is given below: wisted pair cable- upto 300 Hz. Coaxial cable- upto 600 MHz.  Optical fiber cable- upto 2Gbps. Hence,  we choose optical fiber cable for high transmission of data in a network.

Multiple choice

Which of the following is true regarding to circuit switching networks?

  1. Expensive than packet switching networks

  2. Faster in data transmission than packet switching networks

  3. Reliable data transmission than packet switching networks

  4. All of the above

  5. None of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Circuit switching networks are expensive, reliable (no loss), faster in data transmission. Expensive because of end to end connection channel route is dedicated to the communication. Faster as no third party user uses the dedicated channel. Hence, faster. No information is lost hence ensures reliable. Example: Telephone communication.

Multiple choice

What kind of network is BankNet?

  1. Packet switched SONET network

  2. Packet switched X.25 network

  3. Circuit switched SONET network

  4. Circuit switched IP network

  5. Packet switched IP network
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

BankNet is a packet X.25 based network. It has nodes at Mumbai, Delhi, Chennai and Kolkatta.
