Question

Which of the following storage devices directly interacts with the CPU?
1. Tertiary Storage
2. Secondary Storage
3. Primary Storage
4. Hard Disk

Answer 1

Correct Answer - Option 3 : Primary Storage

 The primary memory is an essential component of a computer system. Program and data are loaded into the primary memory before processing. The CPU interacts directly with the primary memory to perform read/ write operations. It is of two types viz. i) Random-access memory (RAM), and ii) Read-only memory (ROM).

• RAM is volatile i.e. as long as the power is supplied to the computer, it retains the data in it. But as soon as the power supply is turned off, all the contents of RAM are wiped out.
• RAM is used to store data temporarily while the computer is working.

Hence the correct answer is Primary Storage.
