The Operating Systems are software that manager other computer software and hardware resources. It provides an interface that allows the user to interact with the computer software and hardware.
Computers and their elements
Computers are complex systems made of hardware and software. Software refers to the computer programs that run on the machine. Hardware refers to the physical components of the device, such as the processor and memory.
Computers run software called the operating system, which provides users with a simpler and easier-to-use computer model. Unix, macOS, and Linux are examples of operating systems. The operating system coordinates the operation of the hardware components.
Each devices has a driver. The driver helps the device communicate easily with the operating system. Normally, when a device is first connected to computer, the operating system notifies the user that the device driver is being installed.
