The computer performs all processing by "calculating," "comparing" and "copying" the data residing in memory (RAM). Programs and data are read from the computer's storage and written into memory. They can also be stored anywhere in the world and written into RAM from a network connection.

Data reside in large blocks in storage known as "sectors." After written into RAM, any single byte can be manipulated independently. This interplay is how computers process all data. See storage vs. memory.

**Calculate - Compute Amounts and Keep Track**

A computer can add, subtract, multiply and divide numbers to compute money amounts and process myriad mathematical algorithms. The computer's calculating capability also 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. Providing the "if this-do that" logic, 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" because computers do an enormous amount of copying (see ordinateur and computers are copy machines).

**It All Begins with Software**

**Compare to Find Things**

**Copy to Display and Print**

**Compare and Copy to Sort**

**Copy and Calculate to Edit**
