Operating Systems Definition and Concepts

Computing systems are composed of software and hardware. For a machine to work, these components need an intermediary to manage the communication between them. Operating system serves this purpose by allowing the user to interact with computer software and hardware. You can think of the operating system as a car driver and the user as a passenger. The user only tells the driver about the destination, and the driver knows how to operate the mechanics of the car (such as changing gears, applying brakes) and takes you to your destination. You don't have to concern yourself with unnecessary details.

The operating system works similarly. Users only need to instruct the computer what to do, and the operating system takes care of all the necessary background processes and resources required to perform the given task without specifying the user about them.
