Question

Which unit holds data temporarily?
A) Secondary storage unit
B) Output Unit
C) Primary Memory Unit
D) Input unit

Answer 1

Primary Memory Unit holds data temporarily.

• It is the main memory of computer system.

• It has limited storage and because of this it is very expensive.

• It loses the data or information stored in it as when the computer system switches off or resets and that's why primary memory is volatile.

• It is often referred as temporary memory.

• It is made up of semiconductor devices.

• In this memory, the stored pieces of data is directly accessed by CPU at a very fast speed.

• The primary memory has two parts -

                 (1) Random Access Memory (RAM) and,

                (2) Read Only Memory (ROM)

Answer 2

Answer:

C) Primary Memory Unit holds data temporarily.

Explanation:

• Data is briefly stored in the Primary Memory Unit. It is the computer's primary memory.
• A primary storage device is any storage device or component in a computer, server, or another computing device that can store nonvolatile data. While the computer is running, it is used to hold/store data and applications momentarily or for a shorter length of time.
• RAM, ROM, CMOS, and flash memory chips are the four types of memory chips. Random-access memory (RAM) and read-only memory (ROM) are two different types of memory. These are also known as a computer's primary memory.
