Windows is an operating system (OS) developed by Microsoft. An operating system is the main software that manages a computer’s hardware and software resources, and provides services for running applications. Here’s a simple breakdown: 🖥 User Interface: Windows gives you a graphical interface (with icons, taskbar, start menu, etc.) so you can easily interact with the computer instead of typing only text commands. 📂 File Management: Lets you create, organize, and manage files and folders. ⚙ Hardware Management: Controls how your computer’s hardware (CPU, memory, storage, printer, etc.) works. 💻 Application Support: Runs software programs like Microsoft Word, Photoshop, Chrome, games, etc. 🌐 Networking: Connects to the internet, local networks, and shared devices. Some popular versions of Windows are: Windows XP (2001) Windows 7 (2009) Windows 10 (2015) Windows 11 (2021, latest major version). 👉 In short: Windows is the system that makes your computer usable — without it, your PC would just be a box of hardware.
