Answer 1

Correct Answer - Option 4 : All of the above

The correct answer is All of the above.

• The memory unit that communicates directly with the CPU is called Primary memory while the memory that cannot be processed directly by the CPU is called Secondary memory.
• Secondary memory is a slower and cheaper form of memory. It can store large amounts of data and information for longer periods of time.
• Primary memory allows the computer to store data for immediate manipulation while secondary memory stores when they are not being processed.
• Examples of Primary Memory: RAM and ROM.
• Example of Secondary Memory: Magnetic Storage (Hard Disk Drive, Floppy Disk), Optical Storage (CD, DVD) and Solid State Storage (Pen Drive, Memory Card)
