MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -For instance, Linux works with several generic drivers that function without the need to install any other software manually. OEMs can create their proprietary device drivers, which need to be installed separately after installing the OS. OEM drivers enable hardware such as keyboards to communicate with the host OS.

Detailed explanation-2: -Purpose of device drivers Device drivers are necessary to permit a computer to interface and interact with specific devices. They define the messages and mechanisms whereby the computer–the OS and applications–can access the device or make requests for the device to fulfill.

Detailed explanation-3: -There are various types of device drivers for I/O devices such as keyboards, mice, CD/DVD drives, controllers, printers, graphics cards and ports. When a driver is included in an operating system, it may be referred to as a kernel-mode device driver.

Detailed explanation-4: -Operating system (OS) – a software that controls and coordinates the computer hardware devices and runs other software and applications on a computer.

Detailed explanation-5: -Device drivers are typically written in C, using the Driver Development Kit (DDK). There are functional and object-oriented ways to program drivers, depending on the language chosen to write in.
