The CPU

A quad core processor will always be faster than a single core processor

• True
• False

Which of these steps does the CPU cycle end with?

• Decode
• Execute
• Fetch

Which of the following may result in better CPU performance? 

• Small Cache
• Low Clock Speed
• Single Core Processor
• Wishful Thinking

Cache memory is...

• Faster than main memory but less expensive
• Faster than main memory and more expen
• Slower than main memory and less expensive
• Slower than main memory but more expensive

Which one of the following tasks are performed by the CPU?

• Fetch data from main memory
• Perform calcularions
• Manage movement of instructions & data to from peripherals
• Fetch instructions from main memory

Clock speed measures what?

• Speed at which instructions are fetched from main memory
• Time taken to perform a single Fetch-Decode-Execute cycle
• Number of Fetch-Decode-Execute cycles that can be completed in 1 sec
• Speed at which instructions are decoded 

What does CPU stand for?

• Critical Processing Unit
• Core Processing Unit
• Common Processing Unit
• Central Processing Unit

A quad core processor will always be more efficient than a single core processor

• True
• False

This acts as a buffer zone to optimize processor performance

• Main Memory
• Cache Memory
• FPU
• ALU

A buffer is...

• A temporary place for a username and password to be used by the operating system
• Encrypted storage of data stored into information
• A temporary store where data is held until it is ready to be processed. 
• A way of capturing data automatically
