Computers are electronic devices that receive input, process information, store data, and produce output. They help us complete tasks such as writing documents, browsing the internet, playing games, creating art, and communicating with people around the world.
Many different devices are considered computers, including desktop computers, laptops, tablets, smartphones, and even smartwatches. Although they come in different sizes, they all perform the same basic functions.
Every computer follows the Input-Process-Output cycle. First, it receives input from devices like a keyboard, mouse, touchscreen, or microphone. Then it processes the information using its processor before displaying or saving the results.
