Unit 3 - RAM and ROM

What is the main difference between primary and secondary storage devices?

• Primary storage devices have faster access speeds than secondary storage devices

• Primary storage devices have a larger capacity than secondary storage devices

• Primary storage devices are non-volatile, while secondary storage devices are volatile

• Primary storage devices are used for backing up and archiving large amounts of data

What is the purpose of primary storage devices?

• To provide a larger storage capacity than secondary storage devices

• To provide faster access speeds than secondary storage devices

• To hold the operating system, programs, and data not currently in use

• To back up and archive large amounts of data

What is the main function of ROM in a computer system?

• To provide faster access speeds than secondary storage devices

• To temporarily store instructions and data for programs being executed

• To hold the operating system when the computer is running

• To contain the very first instructions for the computer and the bootstrap

What is the purpose of the power on self test (POST) program?

• To load the operating system into RAM

• To check the hardware installed correctly and wake up the connected components

• To provide initial startup instructions for the computer

• To execute instructions relating to the operating system

What is the main difference between ROM and RAM?

• ROM is non-volatile, while RAM is volatile

• ROM contains the operating system, while RAM holds the initial startup instructions

• ROM has a larger storage capacity than RAM

• ROM is volatile, while RAM is non-volatile

Why is it important to have primary storage in a computer system?

• To provide a larger storage capacity than secondary storage devices

• To hold the operating system, programs, and data not currently in use

• To execute instructions from the hard disk

• To provide faster access speeds than secondary storage devices

What is the main function of RAM in a computer system?

• To check the hardware installed correctly and wake up the connected components

• To hold the operating system when the computer is running

• To contain the very first instructions for the computer and the bootstrap

• To temporarily store instructions and data for programs being executed

What is the purpose of tertiary storage devices?

• To execute instructions from the hard disk

• To provide a larger storage capacity than secondary storage devices

• To back up and archive large amounts of data

• To hold the operating system, programs, and data not currently in use

What is the main reason for the need of primary storage in a computer system?

• To provide a larger storage capacity than secondary storage devices

• To hold the operating system, programs, and data not currently in use

• To execute instructions from the hard disk

• To provide faster access speeds than secondary storage devices

What is the purpose of virtual memory in a computer system?

• To provide a larger storage capacity than secondary storage devices

• To hold the operating system, programs, and data not currently in use

• To compensate for the shortage of physical memory by temporarily transferring data from RAM to disk storage

• To execute instructions from the hard disk
