Given below are two statements. Choose the correct answer.

Statement I:The devices used for primary or internal memory are semiconductor memories

Statement II:The secondary or auxiliary devices are magnetic and optical memories

ABoth Statement I and Statement II are true ✓ Correct

BBoth Statement I and Statement II are false

CStatement I is true but Statement II is false

DStatement I is false but Statement II is true

Correct answer: (A) Both Statement I and Statement II are true

Explanation

Both statements correctly match memory categories to their device technologies.

Statement 1 is right, since primary or internal memory uses semiconductor devices.

Statement 2 is right, since secondary or auxiliary memory uses magnetic and optical devices.

Semiconductor chips give the speed needed for the processor to work directly with them.

Magnetic and optical media give large, cheap and permanent storage.

Hard disks are magnetic while CDs and DVDs are optical.
