Question 1 of 20

Which of the following physical materials serves as the base layer into which microscopic pits and lands are pressed or burned to create an Optical Storage disc?

Question 2 of 20

Match the Output generation concept (List-I) with its corresponding physical medium (List-II): List-I 1. Rendered visual interface 2. Rendered graphical hardcopy 3. Rendered auditory feedback List-II A. Ink on a page B. Pixels on a monitor C. Sound waves from a speaker

Question 3 of 20

Assertion (A): A touchscreen display functions exclusively as an output device because it renders pixels on a monitor. Reason (R): A direct input device is characterized by an input space that coincides with the display area.

Question 4 of 20

Given below are two statements, one labeled as Assertion (A) and the other as Reason (R). Assertion (A): Headphones and speakers cannot function properly solely using the pure binary digital data processed by the CPU. Reason (R): Acoustic output devices require physical movement to push air; thus, the digital data must first be converted into an analog alternating current to drive their electromagnets. Choose the correct option:

Question 5 of 20

Match List-I (Storage Application) with List-II (Storage Duration/Purpose) correctly: List-I a. Providing a workspace for active CPU tasks b. Retaining data for future retrieval List-II 1. Permanent Archiving 2. Temporary Storage Select the correct answer using the codes given below:

Question 6 of 20

Which of the following is currently recognized as the highest undisputed mountain peak located completely or partially within the undisputed geographical borders of India?

What is the primary cause of 'rotational latency', a severe architectural disadvantage inherent to traditional Hard Disk Drives (HDDs)?

Question 8 of 20

Match the technology to the specific input device it enables: List-I a. Rubber dome and circuit grid b. LED/Laser and DSP c. Charge-Coupled Device (CCD) d. Photodiode List-II 1. Optical Mouse 2. Optical Scanner 3. Light Pen 4. Keyboard

Question 9 of 20

Consider the following statements regarding the input sequence of a standard keyboard: 1. The operating system generates a scan code immediately upon detecting a physical key press. 2. A temporary buffer stores the hardware scan code before it is translated into ASCII. 3. The keyboard controller chip completes the electrical circuit by pushing down on a rubber dome. Which of the statements given above is/are correct?

Question 10 of 20
