Computer systems Quiz

The CPU What does CPU stand for?(1) Which 3 step cycle does the CPU follow?(1) In order to run, name 3 things that the CPU needs?(3)

Clock Speed What unit is clock speed measured in?(1) What does clock speed measure?(1) An advantage of overclocking a CPU?(1) Name two disadvantages?(2)

Cache What is the role of the cache? (2) Why is cache memory preferable to RAM? (1) Complete the sentence: The _______ the cache (2) size is, the _______ instructions can happen simultaneously. Is cache volatile or non volatile? (1)

Cores What is the benefit of having multiple(1) cores? If you have a dual core processor, why (2) does it not reduce the time it takes to run a program by exactly half? How many cores does an octocore (1) processor contain?

ROM What does ROM stand for?(1) Is this non volatile or volatile storage?(1) Define volatile and non volatile(2) Is ROM classed as secondary storage?(1)

Is RAM volatile or non volatile? (1) Which of the RAM, level 1 cache, (2) level 2 cache, that is the a) fastest?b) biggest? What does RAM stand for? (1) Why do computers need RAM? (2) RAM

Label the motherboard with as many components as you can… Try to include CPU RAM (input) Inputs Outputs

Exam style questions a) PC 1 has a single core processor with a clock speed of 2.8GHz. PC 2 has a dual core processor with a clock speed of 2GHz. Explain why the computer with the better clock speed may not be as fast as the one with an extra core. b) Why is it important that both of these computers have a decent amount of RAM? (3) (4)
