Can I make an OS? (LIVE!)
6What is an Operating System?
Imagine your computer is like a busy office, full of people working on different tasks. Now, just like an office needs someone to manage everything so that the workers can do their jobs without getting in each other's way, your computer needs an Operating System (OS) to keep everything running smoothly.
An OS is the software that sits between you (the user) and the hardware of your computer. It manages the resources, like the CPU, memory, and storage, so that you can run apps, save files, and use your computer without needing to tell it every tiny detail.
Here’s what it does:
Manages hardware: The OS helps your computer’s hardware—like the screen, keyboard, and hard drive—talk to the programs you use. It makes sure everything works together.
Runs programs: When you open an app, the OS starts it up and makes sure it gets the resources it needs, like memory and processing power.
File management: The OS organizes your files into folders, helps you find them, and allows you to save and delete them.
User interface: The OS provides the interface you use to interact with your computer, like Windows, macOS, or Linux. This is where you click icons, move your mouse, and type on your keyboard.
Security: It also helps keep your computer secure by managing user permissions, keeping track of who has access to what, and protecting against viruses or other harmful software.
Some popular operating systems you might know are Windows, macOS, and Linux. Each one has its own unique features, but they all perform these core functions.
In short, an OS is the brains behind your computer, making sure everything works together so you can use it easily!
