Which of the following temporarily stores data and programs while you are using them?

a. Read-Only Memory

b. Random Access Memory

c. System software

d. Basic Input/Output system

b. Random Access Memory

Explanation:

In computers, there are 2 types of memory: Volatile and Non-volatile memory. The first one is also known as RAM (Random Access Memory) and it is used by the PC when it needs to store data and programs temporarily and have immediate access when they are used. Notice that this memory is deleted when the computer is shut down.

On the oher hand, the Non-volatile memory (also known as ROM - Read Only Memory) is used to store data in a more permanently way so that crucial Operating System data files as well as all the programs installed are not deleted when the computer is shut down.

Due to the above, the answer is Random Access Memory (RAM).
