Computer System Quiz

What is cache memory primarily used for in a computer system?

• To store user data permanently

• To transfer data more quickly than from RAM for frequently used instructions

• To increase the storage capacity of the system

• To replace the function of the CPU

Which of the following is a characteristic of L1 cache compared to L2 cache?

• L1 cache is slower but has a larger capacity

• L1 cache is faster and typically smaller in size

• L1 cache is used less frequently by the processor

• L1 cache holds data and instructions that are needed less frequently

What is the Von Neumann architecture?

• A type of cache memory

• A design upon which many general purpose computers are based

• A special register used in CPU processing

• A factor affecting CPU performance
