True or False. A modern motherboard uses drive controllers, expansion slots, memory and drive bays.
What is False. It uses ports and connectors, but not drive bays.
400
Explain the difference between a flash drive and a memory card.
What is A flash drive can store up to 128 GB of information, whereas a memory card stores information in digital cameras, video games and other devices. They both are very easy to transport from place to place. Flash drives store multiple files, whereas memory cards store photos, and game content.

True or false. Dye-sublimation uses heat to turn solid dye into a gas that is transferred to a heat coated special paper.
What is False. It’s transferred to special paper, not specifically to heat coated paper.
500
Describe the different functions of the CPU.
What is 1.It’s the brain of the computer and has two parts. 2.It’s housed inside system unit of the motherboard. 3.Preforms arithmetic and logic. 4.Executes instruction, performs calculations and makes decisions.
