CLASSIFICATIONS

What is Hardware?Hardware is a comprehensive term for all of

the physical parts of a computer, as distinguished from the data it contains or operates on, and the software that provides instructions for the hardware to accomplish tasks. The boundary between hardware and software is slightly blurry - firmware is software that is "built-in" to the hardware, but such firmware is usually the province of computer programmers and computer engineers in any case and not an issue that computer users need to concern themselves with.

CLASSIFICATIONS OF COMPUTER HARDWARE SYSTEM:

Cooling Device Class Video and Monitor Device Class Printing Class Networking Device Class Motherboard Mass Storage Class Input Device Class

CLASSIFICATIONS of HARDWARE

These devices are required to remove the waste heat produced by computer components, to keep components within their safe operating temperature limits. Various cooling methods help to improve processor performance and/or to reduce the noise of cooling fans.

COOLING DEVICE CLASS

EXAMPLES of COOLING DEVICES:

COOLING FAN

COMPUTER FAN

Video and Monitor Device Class:

Electronic and visual display devices for computers. The monitor comprises the display device, circuitry, and an enclosure. The video devices describes devices capable of streaming video like webcams, digital camcorders, transcoder, analog video converters, television tuners, and still image cameras.


EXAMPLES of Video and Monitor Devices:

WEBCAM

COMPUTER MONITOR

PRINTING CLASS:

A printer is a peripheral which produces a hard copy (permanent readable text and/or graphics) of documents stored in electronic form, usually on physical print media such as paper or transparencies.


EXAMPLES of PRINTING CLASS:

PRINTER

PRINTER AND PHOTO COPIER

NETWORKING DEVICE CLASS:

Computer networking devices are units that mediate data in a computer network. Computer networking devices are also called network equipment, Intermediate Systems (IS) or InterWorking Unit (IWU). Units which are the last receiver or generate data are called hosts or data terminal equipment.


EXAMPLES OF NETWORK DEVICES

ROUTER

MODEM

MOTHERBOARD:

A motherboard is the central printed circuit board (PCB) in many modern computers and holds many of the crucial components of the system, while providing connectors for other peripherals. The motherboard is sometimes alternatively known as the main board, system board, or, on Apple computers, the logic board. It is also sometimes casually shortened to mobo。


EXAMPLE OF MOTHERBOARD:

MASS STORAGE CLASS:

In computing, mass storage refers to the storage of large amounts of data in a persisting and machine-readable fashion. Devices and/or systems that have been described as mass storage include tape libraries, RAID systems, hard disk drives, magnetic tape drives, optical disc drives, magneto-optical disc drives, drum memory (historic), floppy disk drives (historic), punched tape (historic) and holographic memory (experimental). Mass storage includes devices with removable and non-removable media. It does not include random access memory (RAM), which is volatile in that it loses its contents after power loss. The word "mass" is largely semantic; however, the term is used to refer to storage devices of any size (such as USB drives, which tend to have smaller capacities compared to hard disk drives).


EXAMPLES OF MASS STORAGE CLASS:

USB FLASH DISK HARD DISK

INPUT DEVICE CLASS:

An input device is any peripheral (piece of computer hardware equipment) used to provide data and control signals to an information processing system (such as a computer). Input and output devices make up the hardware interface between a computer as a scanner or6DOF controller.


EXAMPLES OF INPUT DEVICES CLASS:


KEYBOARD

MOUSE

HEADPHONE
