INTRODUCTION TO COMPUTER

🖥️ Introduction to Computers

A computer is an electronic device that receives input, processes data, stores information, and produces output. In today’s modern era, computers are everywhere – from education and healthcare to banking, business, and personal use. Understanding the basics of computers is essential for everyone, no matter what profession they belong to.

👉 In simple terms: A computer takes input, processes it, and gives output. Example: When you type a document, the keyboard is the input, the processor handles the data, and the monitor displays the output.
