Variables and Data Types

When interacting with the computer, at times, a user might be asked to provide a value. At other times, the user might be presented with a value to manipulate. During this interaction, the values, any types of values, are stored and retrieved at will. To make this possible, the computer uses its memory. The computer memory is an area used to receive information, store it, and then make that information available when requested. The computer only makes its memory available to you. It doesn't know and cannot predict the type of value that your particular program would need.
