Class - 12 CBSE Computer Science — Assertion Reason Type Questions

  • Computer Networks

    Assertion. The bus and star topologies are widely used topologies.

    Reason. Bus topology is the simplest topology and star topology is more robust comparatively.


  • Computer Networks

    Assertion. MODEM stands for modulator-demodulator.

    Reason. It is a computer hardware device that converts data from a digital format to analog and vice versa.

    1. Both A and R are true and R is the correct explanation of A.
    2. Both A and R are true but R is not the correct explanation of A.
    3. A is true but R is false.
    4. A is false but R is true.


  • Computer Networks

    Assertion. A modem is a communication device that works on the principle of converting digital data to analog data and vice versa.

    Reason. Modulation is a process of converting digital data to analog form and Demodulation is a process of converting analog data to digital form.


  • Computer Networks

    Assertion. A hub can also act as an amplifier at times.

    Reason. An active hub is capable of amplifying the signal during transmission while a passive hub merely lets the signal pass through it.


  • Computer Networks

    Assertion. A repeater is not like an amplifier.

    Reason. A repeater regenerates a signal thereby removing noise.


  • Computer Networks

    Assertion. A router and a bridge are similar.

    Reason. A router works like a bridge but can handle different protocols unlike bridge.


  • Computer Networks

    Assertion. Hubs and switches can be replaced.

    Reason. While a hub is a broadcast device, a switch is a unicast device.


  • Internet

    Assertion. WWW and the Internet are not the same.

    Reason. WWW is a set of programs, standards and protocols that allows propagation and navigation of multimedia and hypermedia documents.

    1. Both A and R are true and R is the correct explanation of A.
    2. Both A and R are true but R is not the correct explanation of A.
    3. A is true but R is false.
    4. A is false but R is true.


  • Internet

    Assertion. Every document linked to the web has a URL.

    Reason. A location on a net server has a unique address called URL (Uniform Resource Locator).

    1. Both A and R are true and R is the correct explanation of A.
    2. Both A and R are true but R is not the correct explanation of A.
    3. A is true but R is false.
    4. A is false but R is true.


  • Internet

    Assertion. A website is a group of related web pages hosted on a web server.

    Reason. A website is a collection of some hyperlinks.

    1. Both A and R are true and R is the correct explanation of A.
    2. Both A and R are true but R is not the correct explanation of A.
    3. A is true but R is false.
    4. A is false but R is true.
