Q1. The print quality of a printer is given in .......... and printing speed is given in .......... .
A Pages Per Minute (PPM), Dots Per Inch (DPI)
B Chromatic Number (CN), Rotations Per Minute (RDM)
C Dots Per Inch (DPI), Pages Per Minute (PPM) Correct
D Dots Per Inch (DPI), Rotations Per Minute (RPM)
Explanation
Printer output quality is measured in dots per inch because it indicates how many ink or toner dots can be placed in one inch. Printing speed is measured in pages per minute because it tells how many pages the printer can produce in a minute. Pages per minute before dots per inch reverses the two measures. Chromatic number is not a normal printer-quality unit, and rotations per minute is relevant to rotating parts, not page printing speed in this exam context.
