Basic Concepts

What is Computing?

The World of Computing

Computing is all about using computers to solve problems, process information, and make life easier or more fun! At its core, computing means taking input (like data from a keyboard or sensor), processing it in some way, and producing output (like text on a screen or a robot moving).

Key Concepts

  • Input: Data or instructions you give to a computer.
  • Processing: The computer crunches numbers, follows instructions, or sorts information.
  • Output: The results, such as a printed document, a game score, or a song.

Everyday Examples

  • Playing a video game on your tablet.
  • Using a calculator to add up your allowance.

Real-World Impact

Computing powers everything from phones and laptops to cars, hospitals, and even space missions!

Examples

  • Typing an essay in a word processor.

  • Checking the weather on a smartphone app.

In a Nutshell

Computing is the process of using computers to solve problems and process information.

Key Terms
