What is a Computer?
A computer is an electronic device that takes information (like text or numbers), processes it, and gives you results. Think of it as a super-smart tool that follows your instructions to do tasks like browsing the internet, typing essays, or playing games. It stores data (like your school notes, project files) and uses memory to quickly access what you need. There are five generation in computer you can read more about Generation of Computer.
Example: When you type a report on Microsoft Word, the computer takes your keystrokes (input), processes them, and shows the text on the screen (output).
