Which of the following statements are true?
A. CPU speed is measured in kilobytes (KB) and gigabytes (GB)
B. The size of a monitor is measured diagonally across the screen.
C. Laser Printer resolution is measured in dots per inch.
Choose the correct answer from the options given below:
B and C only
Let us examine each statement one by one.
Statement A is incorrect. CPU speed - that is, how many instruction cycles the processor can carry out per second - is measured in Hertz, typically expressed as Megahertz (MHz) or Gigahertz (GHz). Kilobytes (KB) and Gigabytes (GB) are units that measure the SIZE of data or storage capacity, such as file size or RAM/disk capacity, and have nothing to do with processing speed.
Statement B is correct. The size of a computer monitor or screen is conventionally measured as the diagonal distance across the screen, from one corner to the opposite corner, usually expressed in inches.
Statement C is correct. The resolution or print quality of a laser printer is measured in DPI (dots per inch), which indicates how many dots of ink the printer can place within one inch of paper, and this determines how sharp or fine the printed output looks.
Since Statement A is false while Statements B and C are both true, the correct answer is B and C only.
