Which of the following statements is true?

Question

Options

• AAvoid using screen savers for long periods because they don't reduce energy use and may keep
• BUse screen savers for long inactive periods because they reduce the energy use and put the
• CAlternative A is true
• DAlternative B is true

• A
  89% (48)
• B
  2% (1)
• C
  2% (1)
• D
  7% (4)

Explanation

Option A is correct because screen savers were designed to prevent phosphor burn-in on older CRT monitors - not to save energy. In fact, animated or graphically intensive screen savers can consume more power than a normal display, making them counterproductive for energy conservation. The energy-saving alternative is to configure the monitor to sleep or power off during inactivity, which actually reduces consumption.

Option B is wrong because it assumes screen savers reduce energy use, which is the opposite of reality - a screen saver keeps the display fully active and drawing power. Options C and D are simply restatements of A and B respectively, so they rise or fall with their parent choice; since B is false, D is false, and since A is true, C is technically redundant (A itself is the correct answer, not a restatement of it).

Memory tip: Think of "screen saver" as a misnomer - it saves the screen (from burn-in), not energy. When you want to save energy, you need the screen to go dark, not display a bouncing logo.
