Explanation
A computer is an electronic machine that takes in data, works on it, keeps it safe and shows the result. Computers come in different shapes: a desktop computer, a laptop, a tablet, or a phone you use by touching the screen. Think of a kitchen. You bring the ingredients, you cook them, and you serve the food. In the same way, a computer takes in data, processes it and shows it. The parts you can touch are called hardware. The keyboard is for typing. The mouse is for pointing and choosing. The screen shows what is happening. Speakers play sound, a camera lets others see you, and a microphone lets others hear you.

Worked examples
Salma and her cousin plan a video call. They need a screen to see each other, a camera to be seen, a microphone to be heard and speakers to hear.
Mina writes a story. He uses the keyboard to type the words and the mouse to move to another line. He sees his story on the screen.
A tablet has no keyboard or mouse. You use your finger on the screen. It is still a computer, because it takes in data, works on it and shows it.
Class activity
Paper computer. Draw a big screen on a sheet of paper. Draw a keyboard and a mouse below it, and a camera and a microphone on top. Label every part and write its job in a few words. Show your drawing to someone at home and teach them the parts.
