Q1Which input device is most suitable for reading shaded bubbles on a multiple-choice answer sheet?
OMR stands for Optical Mark Recognition. It is designed to detect the presence or absence of marks at fixed positions on a form, such as shaded bubbles in an objective answer sheet. The stem does not ask for reading printed text, magnetic ink, or bar patterns. Those cues would point to OCR, MICR, or a barcode reader respectively. Since the sheet contains bubbles filled by candidates, the defensible answer is OMR reader.
Q2Which statement correctly describes an OMR device?
OMR stands for Optical Mark Recognition. It is used where the computer has to read marked choices, such as shaded bubbles on answer sheets, surveys or application forms. The clue is shaded bubbles or marks on specially printed sheets. Printed paragraph recognition is OCR, cheque code reading is MICR, and sound capture is done by a microphone. Therefore, the statement about reading shaded marks on a sheet correctly describes an OMR device.
Q3Which of the following statements about a touch screen is incorrect?
A touch screen is different from an ordinary display because the same screen can show output and also accept input through touch. The stem asks for the incorrect statement. Options A, B, and C describe true features or common uses: touching icons gives input, the screen also displays output, and smartphones, ATMs, and kiosks often use this technology. Option D denies the input function completely, which contradicts the main purpose of a touch screen. Therefore D is the incorrect statement.
Q4Consider the following statements. Statement 1: A touch screen can accept input when the user touches icons or options on it. Statement 2: A touch screen can also display output like an ordinary screen. Which of the above statements is/are correct?
A touch screen is a good example of a device that has both input and output roles. When the user taps an icon, selects an option or types on an on-screen keyboard, the screen accepts touch input. At the same time, it displays pictures, menus, text and other visual output like a normal monitor. The clue is that the two statements refer to two different roles of the same device, not to two different devices. Hence, both Statement 1 and Statement 2 are correct.
Q5Match List I with List II. List I: I. Barcode reader II. MICR reader III. Graphics tablet IV. Webcam List II: 1. Captures live images or video 2. Reads magnetic-ink characters on cheques 3. Reads printed bar patterns 4. Lets a user draw directly with a stylus
A barcode reader is used at shops and stores to read printed bar patterns, so I matches 3. MICR is Magnetic Ink Character Recognition and is associated with cheque processing, so II matches 2. A graphics tablet accepts freehand drawing or design input through a stylus, so III matches 4. A webcam captures live images or video for the computer, so IV matches 1. The complete correct matching is I-3, II-2, III-4, IV-1.
