The process of entering data into a storage location

adds to the contents of the location
cause variation in its address number
is known as a readout operation
is destructive of previous contents E. None of the above

The correct answer is: E. None of the above

The process of entering data into a storage location is called writing. It does not add to the contents of the location, nor does it cause variation in its address number. It is also not destructive of previous contents.

Here is a brief explanation of each option:

  • A. adds to the contents of the location

This is not correct because writing overwrites the contents of the location.

  • B. cause variation in its address number

This is not correct because the address number of a storage location is fixed.

  • C. is known as a readout operation

This is not correct because reading is the process of retrieving data from a storage location.

  • D. is destructive of previous contents

This is not correct because writing does not destroy the previous contents of a storage location. The previous contents can be retrieved by reading the location before it was written to.
