The computer performs all processing by "calculating," "comparing" and "copying" the data that is read from storage and written into RAM (see storage vs. memory).

**Calculate - Compute Amounts and Keep Track**

A computer can add, subtract, multiply and divide numbers to compute money amounts as well as geometric measurements of all variety. The computer's calculating capability enables it to keep track of its own internal iterations for all the tasks it performs.

**Compare - Match One Set With Another**

The computer can look at two sets of data and determine whether they are equal or which set is higher or lower in value. Comparing is performed for searching, analyzing and evaluating data for countless purposes.

**Copy - From One Place to Another**

The computer can rearrange data for organizing and reporting by copying data from one area in memory to another. In fact, in France and Spain, a computer is actually called an "organizer." See computer.

**It All Begins With Software**

**Compare to Find Things**

**Copy to Display and Print**

**Compare and Copy to Sort**

**Copy and Calculate to Edit**
