Cache and CPU Memory Quiz

What is the purpose of the cache in a CPU?

• To store hidden treasure

• To store food for winter

• To store data for faster access

• To store web browser cache

Why is the cache built into the CPU smaller than the main memory?

• To reduce the cost of production

• To increase the speed of memory access

• To improve CPU performance

What is the advantage of reading a cache line of 128 bytes at once?

• It reduces the time required to read each byte individually

• It allows faster access to memory

• It improves CPU processing speed

• It increases the size of the cache

How does the cache help in executing loops?

• It stores the loop instructions for faster execution

• It increases the size of the loop

• It reduces the time required to fetch loop instructions

• It improves CPU performance

Why are separate caches used for instructions and data?

• To increase the size of the cache

• To reduce the time required to fetch instructions

• To prevent removal of important instructions

• To improve CPU processing speed

What analogy is used to explain the concept of cache?

• A field full of turnips

• A cupboard with turnips in the kitchen

• A backpack with a turnip

• A second level turnip cache

What is the main purpose of the cache in a web browser?

• To store hidden treasure

• To store food for winter

• To store web pages for faster access

• To store web server information

Why does the CPU need to cache data from main memory?

• To reduce the time required to access data

• To increase the size of the cache

• To improve CPU processing speed

• To store more data

What is the disadvantage of RAM compared to CPU speed?

• RAM is more expensive to produce

• RAM runs slower than the CPU

• RAM requires more space on the silicon

• RAM cannot store as much data

What was the speed difference between the RAM and CPU in the BBC micro?

• RAM was twice as fast as the CPU

• RAM was four times as fast as the CPU
