Show answer & explanation
Correct answer: D
Concept
A factual computer-literacy statement can be tested by checking the standard unit, expansion, software category, or measurement convention named in it.
Resolution is described through pixels, USB is a standard bus name, application software performs user tasks, and display size follows a fixed geometric convention.
Application
A monitor’s advertised screen size is the distance between two opposite corners of its visible screen, so the measurement is diagonal and is normally stated in inches.
Contrast
Digital-camera resolution is expressed through pixel dimensions or megapixels; megabytes describe data or file size.
USB expands to Universal Serial Bus; the word “Secure” is not part of its standard name.
Microsoft Excel is spreadsheet application software, whereas system software includes operating systems and related system utilities.
Cross-check
The same diagonal convention is used in manufacturer specifications for monitors and other rectangular displays.
Result
Therefore, the true statement is: The size of a computer monitor is measured diagonally across the screen.
