Many programming languages have been designed so that computers can understand and store various types of information.
This is helpful because people also categorize information.
As an example, numbers and text are two distinct categories of information.
Sometimes it is advantageous for a person to use “3” instead of “three.” Other times the opposite is beneficial. The same is true for a computer.
Additionally, some programming languages have specific categories of information based on content that has been grouped together. You will soon see why this is helpful when working with audio signals.
In all cases, computers can interpret various types of information, as well as store this information for later use.
This section will demonstrate how different types of information can be stored in variables, starting with numbers.
Eventually, this will bring us to how audio information can be stored in a variable.
