Explain why payroll is an example of a function that can be run from a cold site.

What will be an ideal response?

Coldsites are effective for functions that have a time lag built into them. Payroll is an example: paychecks are only issued in week or month increments, and the amounts don't change, so a weekly backup is sufficient to keep the data current. Timeliness and lost data are also why coldsites don't work well for operations based around high transaction processing volumes.
