One component of a computer's internal memory is Random Access Memory. Which of the following statements about the characteristics of RAM are correct? Choose the correct answer from the options given below:

1.RAM can be read from and written to

2.RAM is volatile memory

3.RAM is temporary storage

4.Modern PCs typically have from 2TB up to 32TB

A3 and 4 only

B1, 2 and 3 only ✓ Correct

C1 and 2 only

D1, 2, 3 and 4

Correct answer: (B) 1, 2 and 3 only

Explanation

RAM can be read from and written to, it is volatile, and it acts as temporary storage while a program runs.

Statement 1 is true because the processor freely reads and updates data held in RAM.

Statement 2 is true because RAM is volatile and loses its contents when power stops.

Statement 3 is true because RAM holds data only temporarily for the current session.

Statement 4 is false, since typical PCs have RAM measured in gigabytes, not two to thirty-two terabytes.

That terabyte range is far closer to hard-disk capacity than to main memory size.
