An operating system is a collection of system programs that control computer and any other peripherals connected to it. The program that hides the truth about the hardware from the programmer and present and a nice simple view a named file that can be read & written as “operating system”. Operating system shields the programmer from the interface, the abstraction offers by the operating system is slower & easier to use than the underlying hardware.
Operating system is collection of software which is close to hardware. We can view operating system as a resource – hardware and software collector.
The main functions of operating system are
1. Implementing using interface
2. Sharing hardware among number of users.
3. Allow user to share data
4. Protecting user from each other
5. Control the execution of programs.
