1.ROM is Real Optical Memory
2.RAM stores the instructions you are currently working on
3.ROM stores the BIOS
4.RAM allows the user to read and write data
5.Both RAM and ROM lose their data when the power is turned off
A1, 4 & 5 only
B2, 3 & 4 only ✓ Correct
C1, 2 & 3 only
D3, 4 & 5 only
Correct answer: (B) 2, 3 & 4 only
Explanation
The true claims are Statement 2 that RAM holds the instructions currently in use, Statement 3 that ROM stores the BIOS, and Statement 4 that RAM lets the user both read and write data.
Statement 1 is wrong because ROM stands for Read Only Memory, not Real Optical Memory.
Statement 5 is wrong because only RAM is volatile, while ROM keeps its contents after power off.
RAM is the temporary working memory that empties when the machine is switched off.
ROM is non-volatile and usually holds the start-up firmware.
The BIOS in ROM runs first at power-on to test the hardware and load the operating system.
