Operating system (OS), program that manages a computer’s resources, especially the allocation of those resources among other programs. Typical resources include the central processing unit (CPU), computer memory, file storage, input/output (I/O) devices, and network connections.
What is the role of the kernel of an operating system?
In computing, the ‘kernel’ is the central component of most computer operating systems; it is a bridge between applications and the actual data processing done at the hardware level. The kernel’s responsibilities include managing the system’s resources (the communication between hardware and software components).
What is the role of the user interface of an operating system?
User interfaces. A user interface (UI) refers to the part of an operating system, program, or device that allows a user to enter and receive information. With a graphical user interface (see the right-hand image), the functions are carried out by clicking or moving buttons, icons and menus by means of a pointing device
