Understanding Computer Storage Systems

What is the primary role of secondary storage in a computer system?

• To execute instructions directly

• To replace the need for RAM

• To store programs and data not in use by the processor

• To provide immediate access to the processor

Why is secondary storage necessary in a computer system?

• Because both ROM and RAM are non-volatile

• Because both ROM and RAM are writable

• Because ROM is writable and RAM is non-volatile

• Because ROM is read-only and RAM is volatile

What is the purpose of tertiary storage?

• To provide immediate access to the processor

• To replace secondary storage

• To store temporary data

• For long-term backup and archiving

What happens when a computer is first turned on?

• The CPU retrieves instructions from the hard drive

• The CPU retrieves instructions from ROM

• The CPU retrieves instructions from secondary storage

• The CPU retrieves instructions from RAM

Why must data be transferred back to secondary storage when a computer is shut down?

• Because RAM is volatile and cannot hold data without power

• Because RAM is non-volatile

• Because ROM can store large amounts of data

• Because secondary storage is volatile
