Question Question 3
Explain why we need an Operating system.
Operating system acts as the central coordinator between hardware and software. It fills the communication gap between the hardware and the user. An operating system encompasses all operations such as What to do?, When to do?, How to do? For example, when a button is pressed on a hardware, this information is passed to the operating system which takes care of the final outcome by handling What to do?, When to do? and How to do it?
