Beginning of an operating system
Where is the operating system heading to?
Every machine has its operative rules and computer has no exception. Simple machines such as TV or VCR have accordingly simple functions hence the operation is memorized in the firmware beforehand. However the complicated machine like computer which has almost no limit in application is designed to be used by various ways whenever in need.
The form of gathering system programs together which controls and sets up is called operating system, which enables users can utilize this computer in those various ways. That is, the computer performs at different level depending on what operating system user uses even the hardware (computer) has the same specification. Hence the operating system keeps evolving by including new functionalities as well as hardware.
Assuming CPU corresponds to a human body and mouse and keyboard correspond to hands and feet, you can say operating system corresponds to the knowledge. Operating system not only controls the hardware resources such as CPU, Memory, input and output but also interact between the hardware and application programs. This means the operating system offers the environment for human and computer to communicate with each other and also controls behavior of hardware/ application software, data file management and input/ output processes.
