Which of the following statements is true about computers?

AThe quality of a digital camera's picture depends on its resolution, measured in megabytes.

BUSB stands for Universal Secure Bus.

CMicrosoft Excel is an example of system software.

DThe size of a computer monitor is measured diagonally across the screen. ✓ Correct

Correct answer: (D) The size of a computer monitor is measured diagonally across the screen.

Explanation

A computer monitor's size is measured diagonally from one corner of the screen to the opposite corner.

A digital camera's picture quality depends on resolution measured in megapixels, not megabytes.

USB stands for Universal Serial Bus, not Universal Secure Bus.

Microsoft Excel is application software, not system software.

The diagonal measurement is why a 15 inch and a 17 inch screen differ.

Two monitors with the same diagonal can still differ in aspect ratio.
