Computer Networks Questions

Multiple choice

In dial up remote access, a client uses the ______ to create a physical connection to a part on a remote access server of the private network.

  1. LAN

  2. PLAN

  3. Bank's branch network

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

In dial-up remote access, a client uses a modem (not listed in options) to create a physical connection. LAN is a local network, not a dial-up method. PLAN is not a standard networking term. Bank's branch network is unrelated to dial-up technology.

Multiple choice

Which is not an example of centralised controlling topology?

  1. Bus

  2. Loop

  3. Both (1) and (2)

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Bus topology is a decentralised topology where all nodes connect to a central cable. Loop (ring) topology is also decentralised as each node connects to two others. Centralised controlling topologies include star and hierarchical where one node controls communication.

Multiple choice

Which of the following was the precursor of internet?

  1. APPLENET

  2. ARPANET

  3. TELNET

  4. ALLNET
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

ARPANET (Advanced Research Projects Agency Network) was the first wide-area packet-switched network and is widely recognized as the precursor to the modern internet.

Multiple choice

Which type of network is used within a city?

  1. LAN

  2. CAN

  3. MAN

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

It covers area larger than LAN but smaller than WAN covering an area of 2 to 100 km. Therefore, MAN allows the sharing of resources within a city.

Multiple choice

Base station and MSC relate to

  1. ISO-OSI Model

  2. Cellular radio

  3. ARPANET structure

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Base station and Mobile Switching Centers (MSC) are related to radio relays. The BSC may be coupled to a mobile switching center (MSC) and a packet data serving node (PDSN) between MSCs, circuit connections provide the handover mechanism which services calls as users roam from one service zone to another.
