What is an Operating System?
Unlock Audio Lesson
Today, we're discussing operating systems, commonly known as OS. An operating system is the software that manages computer hardware and software resources. Can anyone tell me what they think the main function of an OS is?
Is it to run applications?
That's one important function! The OS indeed runs applications, but it also handles file management, process management, device management, and user interfaces. To remember these functions, think of the acronym 'FPDUI' — File, Process, Device management, User Interface.
What do you mean by device management?
Great question! Device management refers to how the OS communicates and coordinates with peripherals such as printers and scanners. Let's keep this acronym in mind as we learn more about popular operating systems.

Now that we have defined an operating system, let's go over its functions in more detail. Who can name one of the functions we discussed?
File management!
Exactly! File management is crucial for organizing and retrieving data. Another function we discussed was process management. Can anyone explain why this is important?
Because it ensures programs run smoothly without crashing, right?
Correct! Process management ensures that multiple applications can operate without interfering with each other. It manages CPU time allocation for various tasks. Always remember that the OS is what keeps everything running smoothly, much like a traffic controller.

Now, let's discuss some popular operating systems. Can anyone name one?
Windows!
Yes, Windows is one of the most widely used operating systems, especially for PCs. What do you think is the main advantage of using Windows?
It has a lot of software available?
Exactly! Windows supports a wide range of applications, making it very user-friendly. Now, who can name another OS?
Linux!
Right! Linux is popular among developers and is open-source, which means anyone can contribute to its development or use it for free. What do you think might attract someone to use Linux over Windows?
It’s customizable and more secure, I think.
Absolutely! Customization and security are two major benefits developers appreciate. Let’s not forget macOS, which is favored for its smooth user interface, especially for creative tasks. Each OS serves different needs!
