An operating system is a software component that acts as the core of a computer system. It performs various functions and is essentially the interface that connects your computer and its supported components. In this article, we will discuss the basic functions of the operating system, along with security concerns for the most popular types.
Basic Operation
Drivers play a major role in the operating system. A driver is a program designed to comprehend the functions of a particular device installed on the system. A driver enables the operation of numerous devices, including your mouse, keyboard printer, video card and CD-ROM drive by translating commands from the operating system or the user into commands understood by the associated component. It also translates responses from the component back to the operating system, software application or user.
The operating system performs other functions with system utilities that monitor performance,
debug errors and maintain the system. It also includes a set of libraries often used by applications to perform tasks to enable direct interaction with system components. These common functions run seamlessly and are transparent to most users.
