What is an Operating System?
An operating system (OS) is the most crucial software that runs on a computer which means that every computer system must have an Operating System to make it usable. Mobile phones, laptops, tablets, desktop computers, routers, and the like are examples of computers.
Popular Operating Systems you might have used or heard of:
- Windows 7, 8, 9, 10, and 11 used for PCs and tablets
- IOS used for apple devices such as iPhones and iMacs
- Android is mostly used for phones such as Samsung Galaxy phones and Tablets
- Linux known for mostly server OS
An OS is a bridge or mediator between the person using the computer and the computer. The user interacts with the OS then the OS communicates with the computer. Furthermore, an operating system manages applications such as Microsoft word, google chrome, Mozilla Firefox, and Microsoft excel. Application software can only be installed and used on top of an OS.
Whenever you buy a Mobile Phone, PC, or laptop, the Operating system is typically already installed in it but you have the ability to upgrade or change the OS that comes with it. Microsoft Windows, macOS, Android, and Linux are the most common Operating Systems that are installed whenever you buy your Phone, PC, or laptop.
