HOW COMPUTER HARDWARE WORKS - PRACTICE
TEST- COMPUTER SCIENCE.
Trusted by students across multiple disciplines!
What is the function of the motherboard? - Answer: The motherboard distributes
electricity and handles communication between CPU, RAM, and other hardware
components.
How does the power supply contribute to the functioning of a computer? - Answer: The
power supply transfers electricity to the motherboard for computer use.
What are examples of input and output devices? - Answer: Examples of input and
output devices include the keyboard and mouse.
What is the CPU responsible for? - Answer: The CPU runs programs, carries out
instructions, and makes calculations.
What is the purpose of RAM? - Answer: RAM is used for short-term memory to rapidly
perform immediate tasks.
What is the difference between RAM and a hard drive? - Answer: RAM is volatile
memory that is lost when the computer is turned off, while a hard drive is non-volatile
and saves data even when powered off.
How does the CPU execute instructions? - Answer: The CPU executes instructions by
fetching them from RAM, decoding them into binary, and then processing them.
Why is RAM important for computer performance? - Answer: RAM increases the speed
of applications by loading information into it for quick access and availability of
previously-accessed data.
