Understanding Inputs and Outputs

Definition

Inputs

The data or information is provided to a program to process.

Definition

Outputs

The results or responses produced by the program after processing the inputs that are available to the user or another system.

Example

Consider the formula for average velocity $ V = \frac{s}{t} $
Inputs:
- s: total displacement (distance travelled)
- t: time elapsed
Output:
- V: average velocity
In this example, the inputs s and t are essential for calculating the output V.
Without these inputs, the program cannot perform the calculation.

Note

Inputs and outputs are not limited to numerical data.
They can include text, files, images, user actions, and more, depending on the program's purpose.

Why do We Need Inputs and Outputs?
