- A.
OCR
- B.
MICR
- C.
OMR
- D.
POS
Correct Answer
C. OMRExplanation
OMR stands for Optical Mark Recognition, which is a technology used to detect and analyze marks made on a paper. It is commonly used in marking multiple-choice examination questions because it can quickly and accurately read and process the marks made by students on the answer sheets. OCR (Optical Character Recognition) is used to recognize and convert printed or handwritten text into machine-readable format, MICR (Magnetic Ink Character Recognition) is used in banking for processing checks, and POS (Point of Sale) refers to the system used for transactions in retail stores. Therefore, OMR is the most suitable option for marking multiple-choice examination questions.Rate this question:

Which of the following is the most suitable output device to print an architectural drawing on a very large paper?
- A.
Laser printer
- B.
Inkjet printer
- C.
Dot-matrix printer
- D.
Plotter
Correct Answer
D. PlotterExplanation
A plotter is the most suitable output device to print an architectural drawing on a very large paper. Unlike laser printers, inkjet printers, or dot-matrix printers, plotters are specifically designed to print large-scale drawings with high precision and accuracy. They use a pen or a set of pens to create continuous lines on the paper, resulting in detailed and clear prints. This makes them ideal for printing architectural drawings, which often require large paper sizes and intricate details.Rate this question:

Which of the following devices is used in banks to process cheques?
- A.
OCR
- B.
MICR
- C.
OMR
- D.
POS
Correct Answer
B. MICRExplanation
MICR (Magnetic Ink Character Recognition) is the correct answer because it is a technology used in banks to process cheques. MICR uses special ink and characters that are printed on the bottom of cheques in magnetic ink. This technology allows banks to quickly and accurately read the information on the cheques, such as the account number and the amount, by using magnetic sensors. This helps in automating the cheque processing system and reduces errors in data entry.Rate this question:
