3 Vocabulary Terms - Define/Illustrate
1. Input 2. Output 3. Function
1. Input: Input refers to the data or information that is entered into a system or program. It can be in the form of text, numbers, or any other type of data. For example, when a user types a message on a keyboard or clicks a button on a website, the text or button click is considered as input.
2. Output: Output is the result or information that is produced by a system or program after processing the input. It can be displayed on a screen, printed on paper, or saved in a file. For example, when a user inputs a mathematical calculation in a calculator, the result displayed on the calculator screen is considered as output.
3. Function: In programming, a function is a block of organized, reusable code that performs a specific task. It takes input, processes it, and produces output. Functions are used to divide a program into smaller, manageable sections and to avoid repetition of code. For example, a function to calculate the area of a rectangle would take the length and width as input, perform the calculation, and output the result as the area of the rectangle.
