FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -They enable the computer’s operating system (OS) to interface with the hardware for which they were developed. And through a computer bus that links the device to the computer, the drivers and the device communicate. Device drivers must receive advice from the operating system to access and execute device instructions.

Detailed explanation-2: -An operating system uses a graphic user interface (GUI), a combination of graphics and text, that allows you to interact with the computer or device. Every computer or smart device needs at least one operating system to run applications and perform tasks.

Detailed explanation-3: -A device driver is a piece of software that allows your computer’s operating system to communicate with a hardware device, the driver is written for. Generally a driver communicates with the device through the computer bus which is used to connect the device with the computer.

Detailed explanation-4: -Device drivers relay requests for device access and actions from the operating system and its active applications to their respective hardware devices. They also deliver outputs or status/messages from the hardware devices to the operating system and thus to applications.

Detailed explanation-5: -The operating system (OS) manages all of the software and hardware on the computer. It performs basic tasks such as file, memory and process management, handling input and output, and controlling peripheral devices such as disk drives and printers.
