What is OS?
Operating system is a software that manages computers hardware and software resources. It provides common services for a computer. It also acts an Intermediary between Computer user and Computer Hardware.
Why we need Operating System to run Computers?
So, what will I do with the system or what will I put into the system if there is no OS?
Because I don’t have an OS, I will write a standalone program or I can say there will be a single application that will be programmed into the system (flashed into the static memory of the system such as a Flash memory or SRAM or EEPROM etc.).
So, this standalone application has to initialize the hardware components (Display, Sound hardware, UART, Timer etc. each one of them is a hardware component) in the system. Because I have only one application running, I can have only a single point of execution at a single time. So, in the application I can only deal with only one hardware at an instant. To use another hardware component first I have to complete the task with the current hardware component.
There is nothing wrong with that. The only problem is I cannot use my system to it’s full potential. I can use only one hardware component at a time even though I have multiple hardware components in the system.
Then someone has thought that the system can be used in a much better way and brought the concept of OS (probably ?DOS). Initially the OS was still capable of executing a single application and a single user at an instance.
Gradually, the OS infrastructure has grown to a huge software system that has the ability to run multiple applications, multiple users while still be able to deal with multiple hardware components at the same time and providing an illusion that all of the hardware components of the system can be used at the same time.
An OS provides several services to applications, such as: efficient CPU time allocation to different applications (CPU scheduling), process management, memory management, synchronization between different applications (so that no two applications in the system would fight for the same resource), etc., to run multiple applications and multiple users on a system.
So, in simple words: an OS is a software component that helps utilize a hardware to its full potential while maintaining an illusion that all if the hardware can be used at the same time and there can be literally unlimited application that can run.
Here I have a post that briefs out what is an OS and why do we need an OS
