A plotter is best suited for producing which of the following?
- A.Photographs on glossy paper
- B.Carbon copies of receipts
- C.Maps and engineering drawings
- D.Cash memos at a billing counter
Correct answer
Explanation
The correct answer is C, maps and engineering drawings. A plotter holds a pen against the paper and moves it, so it draws continuous lines rather than building the image out of dots. That is exactly what large technical drawings need, which is why plotters are used for architectural plans, survey maps and output from design software. The drum plotter and the flatbed plotter are its two types.
Option A, photographs on glossy paper, calls for an inkjet or a photo printer that can lay down blended colour dots. Option B, carbon copies of receipts, needs an impact printer such as the dot matrix, because only a strike through the ribbon presses onto the sheet below. Option D, cash memos at a billing counter, is the ordinary work of a small thermal printer. Note also that a plotter is an output device, although its pen makes it look like a drawing input.

View allWhich of the following is both an input and an output device?
- A.Scanner
- B.Plotter
- C.Touchscreen
- D.Light pen
Show answer
A touchscreen accepts a finger tap or a stylus stroke as input and displays the result on the very same surface, so the one piece of hardware performs both jobs.

- A.Processing of bank cheques
- B.Reading objective answer sheets
- C.Billing at a retail counter
- D.Recording fingerprints
Show answer
MICR stands for Magnetic Ink Character Recognition. The line of characters printed along the foot of a cheque is set in magnetic ink in the E-13B font, and the reader identifies each character from its magnetic signal, so the cheque is sorted correctly even when it has been folded, stamped…

- A.Bit
- B.Pixel
- C.Byte
- D.Dot pitch
Show answer
The word is a contraction of picture element. A screen image is a grid of these points, and the number of them across and down the screen is what is quoted as the resolution of the monitor, so a higher pixel count means a finer picture.
