Which of the following will happen when data is entered into a memory location?

AIt will add to the content of the location

BIt will change the address of the memory location

CIt will erase the previous content ✓ Correct

DIt will not be fruitful if there is already some data at the location

Correct answer: (C) It will erase the previous content

Explanation

Writing data into a memory location replaces whatever was previously stored there.

It does not add to the existing content, the old value is overwritten.

It does not change the address, only the contents at that address.

It works regardless of whether data was already present, so it is not fruitless.

A write operation is destructive to the earlier contents of the cell.

Reading, by contrast, leaves the stored value untouched.
