1. Define hardware. Differentiate between device driver and firmware.

Computer hardware refers to the computer's tangible components or delivery systems that store and run the written instructions provided by the software. Computer hardware includes the physical parts of a computer, such as the case, central processing unit, random access memory, monitor, mouse, keyboard, computer data storage, graphics card, sound card, speakers and motherboard. 

Device Drivers


Device driver is a particular type of software program that enables the operating system to communicate with and control devices. Device drivers are pretty much device-specific meaning they are written and distributed by the manufacturer of a particular device.

Firmware, on the other hand, is a special form of software that enables a device to perform functions without the need of installing additional software. Firmware is program code stored in a hardware device, typically in non-volatile memory such as read-only memory or flash memory.

Device drivers are operating system-specific and hardware dependent that enable operating system and other software programs to access hardware functions without worrying about the details on how the hardware devices work. Without a device driver, the OS won’t be able to communicate with a hardware device.

Firmware, on the other hand, is software permanently etched into a hardware device that enables the device to perform functions like basic input/output tasks, without the need of installing additional software. It carries out the integral functions of hardware devices.

The purpose of a device driver is to ensure smooth functioning of hardware device for which it is intended to work and to also allow it to be used with different operating systems. For example, a graphics driver enables the OS to communicate with and control your graphics card or video card or on-board graphics.

Firmware, on the other hand, is a software program that gives life to the hardware device, programming it to give instructions in order to communicate with other devices and perform functions like basic input/output tasks.

Device drivers enable operating system and other software programs to access hardware functions without worrying about the details on how the hardware devices actually work.

Firmware is also software, in the context that it is program code. The difference lies in how the program code is stored. Firmware includes the internal set of instructions used by a hardware device for initiation and operation, often encoded in non-volatile memory.
