Mini Lesson

A computer is a tool that helps us work, learn, and create. To use a computer well, you need to know its main parts and how to manage the files you make.

Main Parts of a Computer

  • Screen (monitor) — shows you everything happening on the computer.
  • Keyboard — lets you type letters, numbers, and symbols.
  • Mouse — lets you click, select, and move things on the screen.
  • CPU (tower or laptop body) — the brain that runs all the programs.
  • Storage (hard drive or USB) — keeps your files safe so you can use them again.

What Is File Management?

File management means keeping your work organised on a computer. You create files, give them clear names, save them in the right folder, and close them when you are done.

Steps to Work with a File

  1. Open the application (e.g. a word processor or drawing program).
  2. Create a new file and give it a clear name.
  3. Type or draw your content inside the file.
  4. Save the file — use Ctrl + S or the Save button so your work is not lost.
  5. Close the application when you have finished.
💡

Save your work every few minutes — not just at the end. If the power goes off, unsaved work is gone!
