The total number of messages handled by a computerized telephone system on a daily basis is an example of:

Frequency
Updating
Volume
All of the above E. None of the above

The correct answer is C. Volume.

Frequency is the number of times something happens in a given period of time. Updating is the process of making something more up-to-date. Volume is the amount or quantity of something.

In the case of a computerized telephone system, the total number of messages handled on a daily basis is an example of volume. This is because it is the total amount of messages that are handled by the system in a given day.

The other options, frequency and updating, are not correct because they do not accurately describe the total number of messages handled by a computerized telephone system on a daily basis.
