Computing time is the exact time required for a computation. It is calculated by following the steps given below.

Step 1: Count how many operations of each type have to be carried out
Step 2: Multiply the numbers got from Step 1 by the times required for the execution of operations
Step 3: Add the products for the total estimate

Exact time required for each type of operation is known for each machine. But number of operations required for a given problem can be determined only when the coding is completed.
