Select the correct statement about the difference between RAM and ROM.
RAM is volatile memory, while ROM is non-volatile memory.
RAM is used to store permanent data, while ROM is used for temporary data.
ROM is faster than RAM in all operations.
RAM retains data even when the power is off, but ROM does not.
Select the correct examples of secondary storage devices and their uses.
Hard disk - storing large files, USB flash drive - transferring data
Monitor - displaying images, Keyboard - typing text
RAM - temporary data storage, CPU - processing data
Printer - printing documents, Mouse - moving cursor
One function of the central processing unit (CPU) is to:
Process instructions and control the operations of the computer
Store large amounts of data permanently
