Performance of Computer Systems

What is cache memory?

• It is used to permanently store data and programs
• It is used to store numbers
• It is used between the RAM and CPU to improve performance by holding data that has just been or is about to be processed.
• It is used to store letters  

A technique used by the CPU to overlap stages in the fetch-decode-execute cycle.

• Overlock

• Streamlining

• Pipelining

• Storage

Which of the following does NOT affect the performance of a CPU?

• Clock Speed

• Number of Cores

• Amount of Cache

• Type of Cache

• Number of CPU pins

Clock speed is measures in

• bytes
• bits
• time
• hertz

___________ is the action of increasing a component’s clock rate, running it at a higher speed than it was designed to run.

Which level of cache is the fastest but has the smallest capacity?

• Level 1
• Level 2
• Level 3
• Level 4

The higher the CPU's clock speed...

• The more cache the CPU has

• The more cores the CPU has

• The more data can be stored

• The greater number of instructions can be carried out per second

Is a computer with a quad core CPU guaranteed to be quicker than a dual core CPU?

• No, it depends on whether the program can multitask

• No, it depends on the size of the RAM

• Yes, more cores means it will be quicker no matter what

Can the width of the System Bus affect the performance of the CPU?

• Yes

• No

What does GPU stand for?

• Graphical Processing Unit

• Good Parallel Unit

• Graphics Printing Unit

• Graphical Programming Unit

• Graphics Producing Unit
