J277 - 1.1 CPU Performance Factors

What is the primary role of cache memory in a computer processor?

• To store all the data permanently

• To store frequently used instructions and data

• To increase the size of the hard drive

• To replace the need for RAM

Why is it inefficient for a processor to fetch frequently used instructions from RAM each time?

• RAM is slower than cache memory

• RAM is more expensive than cache memory

• RAM can only store video files

• RAM is located outside the computer

Which of the following tasks is considered processor-intensive?

• Browsing the internet

• Video editing

• Typing a document

• Listening to music

What is one of the main reasons manufacturers improve processors?

• To increase the size of the computer

• To make computers heavier

• To enhance processor performance

• To reduce the number of keys on a keyboard

Where is cache memory typically located in relation to the processor?

• On the hard drive

• Inside the monitor

• Close to or directly on the processor

• In the power supply unit

What happens when a computer system runs programs?

• It only uses the hard drive

• It swaps data in and out of cache memory and RAM

• It shuts down automatically

• It only uses the graphics card

Which of the following is NOT a factor that affects processor performance?

• Cache size

• Processor clock speed

• Colour of the computer case

• Number of processor cores

What is the benefit of having a larger cache memory?

• It makes the computer heavier

• It allows for faster access to frequently used data

• It increases the computer's screen size

• It reduces the need for a power supply

How does improving processor technology benefit users?

• It makes computers more colourful

• It allows users to perform tasks more quickly

• It increases the number of USB ports

• It reduces the need for a mouse

What is the relationship between cache memory and RAM?

• Cache memory is slower than RAM

• Cache memory is used to store data permanently

• Cache memory is used to store frequently accessed data to reduce the need to access RAM

• Cache memory is located in the monitor
