• Main memory (RAM)

• Registers

• Secondary storage

Which level of memory hierarchy is typically the largest in terms of storage capacity?

• Registers

• Cache memory

• Main memory (RAM)

• Secondary storage

What is the primary purpose of cache memory?

• To store data permanently

• To provide temporary storage for data being processed

• To increase the speed of data access for frequently used information

• To serve as backup storage

Which of the following is NOT a level of cache memory?

What is the role of registers in a CPU?

• To store the operating system

• To store frequently accessed data and instructions for immediate use

• To act as permanent storage

• To manage input/output operations

Which memory type has the shortest access time?

Which of the following statements about main memory (RAM) is true?

• It is slower than cache memory but faster than secondary storage

• It is the fastest type of memory in the hierarchy

• It is used for permanent data storage

• It is smaller in capacity compared to registers

What is the primary disadvantage of secondary storage compared to other memory types?

• High cost

• Slow access time

• Volatility

Which component in the memory hierarchy typically stores the operating system and software applications?

• Registers

• Cache memory

• Main memory (RAM)

• Secondary storage

What is a 'cache miss'?

• A successful retrieval of data from cache memory

• The unavailability of a cache in the system

• A situation where the required data is not found in the cache memory

• The process of writing data to the cache
