what is an operating system?
An operating system is the most important software that runs on a computer, because it manages the computers memory,processes as well as all of it's software and hardware. It controls the whole device e.g the input the output etc.
Without an operating system a computer would be useless.

- kernel: is one of the main components to an operating system it acts as a bridge between applications and the data processing done by the hardware.it is responsible for managing the systems resources so the communication between the hardware and software component.
- user interface: is the way a person would control the software applications and the hardware device, a good user interface would be one that provides a 'user-friendly' experience which would allow the 'user' to interact with the hardware or software in an easy and natural way.
What are the main Functions/ Features of an operating system?
- it manages/controls all the hardware and the software
- it powers up the computer s you can use it
- Provides a user interface so you can interact with the computer and the computer can interact with user.
- it manges memory and storage
- it allows you to open and use programs
- The operating system handles the errors/crashes that could happen so you computer doesn't turn off and have to be powered up again.
- It also allows output and input to work with purpose.
The diagram shows, that the operating system forms the gateway between the user and the components of a computer. this is necessary because we can't physically interact with the components of a computer there is no way of doing it.we interact with the computer using input and output which form part of the user interface and are controlled by the operating system.
