Data Types

Different Kinds of Data

Just as you wouldn't store milk in a paper bag, computers store different kinds of data differently. An integer is a whole number (like counting apples: 1, 2, 3). A real/float has decimal places (like money: £19.99). A string is text (like a name: "Alice"). A boolean is true/false (like a light switch: on or off). A character is a single letter ('A'). Choosing the right type matters!
