Question 13 of 20
Which of the following describes the fundamental working mechanism of a Capacitive Touchscreen?
Question 14 of 20
Consider the following statements regarding OCR technology:
1. OCR completely eliminates the need for manual retyping of physical texts.
2. OCR software requires Intelligence Character Recognition (ICR) to interpret varied human handwriting.
3. OCR operates purely on a binary level, identical to OMR.
Which of the statement(s) given above is/are correct?
Question 15 of 20
Which of the following hardware limitations is explicitly associated with a modern optical mouse?
Question 16 of 20
Consider the following statements regarding Resistive Touchscreens:
1. They utilize two flexible, electrically conductive layers separated by a microscopic gap.
2. They operate by detecting the distortion of a continuous electrostatic field.
3. Physical pressure is required to cause the layers to touch and register a coordinate.
Which of the statements given above is/are correct?
Question 17 of 20
What is the key difference between how a Direct Input Device and an Indirect Input Device operate?
Question 18 of 20
Given below are two statements, one labeled as Assertion (A) and the other as Reason (R).
Assertion (A): Documents produced by Thermal Printers are generally deemed unsuitable for permanent, long-term archival storage.
Reason (R): Thermal printers rely on a heat-triggered chemical reaction on specialized paper, a process that is unstable and causes the prints to naturally fade over time.
Choose the correct option:
