What is the purpose of the CPU?

• To process all the data and instructions.
• To turn the computer on.
• To create PowerPoint presentations.
• To provide power to the computer.

What are the two other parts of the CPU that you learned?

• RAM & ROM
• Hard Drive & Motherboard
• The ALU and Cache

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

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

Which of the following CPU's will have a better better performance:
A: 3 GHz Quad Core CPU
B: 3 GHz Duel Core CPU 

• A
• B

How does clock speed affect computer performance?

• The higher the clock speed the slower the computer will run.
• It improves the amount you can store on the computer.
• The higher the clock speed the better the performance.
• It will make loading program slower

What is a bus?

• A circuit that connect one part of CPU to other components.
• A type of long term memory
• A type of permanent memory
• A method of transport

What is cache memory?

• A very large, temporary memory
• A very small but expensive memory
• It is used to store data and programs permanently
• It is a type of payment

How can a bigger cache improve CPU performance?

• By being able to carry out more calculations
• By being able to store more recently used instruction inside the CPU for quicker access times
• By being able to 

Clock speed is:

• Number of times the computer is used
• Number of instructions a computer can handle per second
• Time on a computer

Which component would calculate the result of 6 * 4?

• Accumulator
• ALU
• Control Unit
• MAR
