Operating System Practice Exam

Operating System Creation Practice Exam

An Operating System (OS) is the main software that makes a computer or device work. It connects the hardware, like the processor and memory, with the software, like apps and programs. The OS helps in performing everyday tasks such as saving files, running applications, and connecting to the internet. Without it, a computer would just be a collection of parts that can’t do much on their own.

In simple words, the OS acts like a manager that makes sure everything in the computer works together smoothly. It makes the machine user-friendly, so people can give commands, use applications, and get work done without worrying about the technical details inside the system.
