A computer is a device that accept information and manipulates it for

some result based on program of instruction on data is to be

processed. The two principal characteristics of a computer are: It

responds to a specific set of instructions in a well-defined manner. It

can execute a prerecorded list of instructions (a program).

MEANING OF HARDWARE

All components of the computer that you can

feel and touch and more like see, these

include the monitor, the keyboard, the

speakers, the mouse and the CPU and all thatis unit are all referred to as the hardware.

Generally it refer to the physicals artifacts of a

technology which means physicals componentof a computer system.

1.MOTHERBOARD

It is the body of computer . Component are directly

attached to the motherboard .

A: CENTRAL PROCESSING UNIT (CPU)

The Central Processing Unit (CPU) is the brain of the computer. Modern CPU's are

what are called 'integrated chips'. The idea of an integrated chip is that several

processing components are integrated into a single piece of silicon. Without the

CPU, you have no computer. The CPU is composed of thousands of transistors. It

is the chip set which mediates communication between CPU and othercomponent of system including main memory

B:RANDOM ACCESS MEMORY(RAM):

Random Access Memory or RAM is the memory that the computer uses to

temporarily store the information as it is being processed. The moreinformation being processed the more RAM the computer needs.

One of the first home computers used 64 kilobytes of RAM memory

(Commodore 64). Today's modern computers need a minimum of 64 Mb

(recommended 128 Mb or more) to run Windows or OS 10 with modern

software.

PARTS OF HARDWARE


8/12

The component that supplies power to a computer. Most personal computers can

be plugged into standard electrical outlets. The power supply then pulls the

required amount of electricity and converts the AC current to DC current. It alsoregulates the voltage to eliminate spikes and surges common in most electrical

systems. Not all power supplies, however, do an adequate voltage-regulation job,

so a computer is always susceptible to large voltage fluctuations. It include power

code switch and cooling fans. supplys power at appropriate voltage to mother

board at internal drive.

2.POWER SUPPLY

3. VIDEO DISPLAY CONTROLLER

A device that accepts video signals from a computer and provides information in a visual

form. It produces the output for video display unit.

4. Removable Media Devices

A. COMPACT Disc

A compact disc [sometimes called disk] (CD) is a small, portable, round medium made of

molded polymer (close in size to the floppy disk) for electronically recording, storing, and

playing back audio, video, text, and other information in digital form. Tape cartridges and CDs

generally replaced the phonograph record for playing back music. At home, CDs have tended

to replace the tape cartridge although the latter is still widely used in cars and portable

playback devices.

B. Digital Versatile Disc (DVD)

well as

Digital versatile disc (DVD) is apopular storage format for movies, games and software.

The rate of acceptance of the DVD format developed faster than any

historically. With a storage capacity of 5-20gigabytes, depending on the format

been sufficient capacity to re-establish the way we watch movies, play video games, asmany other potential applications. As successful as this technology has become, it is not

underway to assist this technology in its ever-changing evolution.

C. BLU ray Disc

BLU-ray (not Blue-ray) also known as B l u-ray Disc (BD), is the name of a next-generation optical

disc format jointly developed by the B l u-ray Disc Association (BDA), a group of the world'sleading consumer electronics, personal computer and media manufacturers (including Apple,

Dell, Hitachi, HP, JVC, LG, Mitsubishi, Panasonic, Pioneer, Philips, Samsung, Sharp, Sony, TDK and

Thomson). The format was developed to enable recording, rewriting and playback of high-

definition video (HD), as well as storing large amounts of data. The format offers more than five

times the storage capacity of traditional DVDs and can hold up to 25GB on a single-layer disc

and 50GB on a dual-layer disc. This extra capacity combined with the use of advanced video andaudio codec's will offer consumers an unprecedented HD experience.

A floppy disc is a data storage medium that is composed of a disk of thin, flexible ("floppy")

magnetic storage medium encased in a square or rectangular plastic shell.

Floppy disks are read and written by a floppy disc drive or FDV the initials of which should not

be confused with "fixed disk drive", which is another term for a (non removable) type of harddisk drive . Invented by the American information technology company IBM floppy disks in

8 inch, 5 inch and 3 inch forms enjoyed nearly three decades as a popular and ubiquitous

form of data storage and exchange, from the mid-1970sto the late1990s

D. Floppy Disc

E.ZIP DRIVE

The Zip drive is a medium-capacity removable disk storage system, introduced by lomega in

late 1994. Originally, Zip disks launched with capacities of100 MB but later versions increasedthis to first 250 MB and then 750 MB.

The format became the most popular of the super-floppy type products which filled a niche in

the late 1990s portable storage market. However it was never popular enough to replace the

3.5-inch floppy disk nor could ever match the storage size available on rewritable CDs and

later rewritable DVDs.USB flash drives ultimately proved to be the better rewritable storage

medium among the general public due to common availability of USB ports built into mostmodels of personal computer


11/12

F. USB FLASH DRIVE

A small, portable flash memory card that plugs into a computers USB port and functions as a

portable hard drive. USB flash drives are touted as being easy-to-use as they are small enough

to be carried in a pocket and can plug into any computer with a USB drive USB flash drives

have less storage capacity than an external hard drive, but they are smaller and more durablebecause they do not contain any internal moving parts.

G.INTERNAL STORAGE

A term used to describe any location where information can be held permanently in general

term hardware that keeps data inside computer for later use and remain constant even when

computer has no power.H.HARD DISK

A hard disk is part of a unit, often called a "disk drive," "hard drive," or hard disk drive,"

that stores and provides relatively quick access to large amounts of data on an

electromagnetically charged surface or set of surfaces. Today's computers typically come

with a hard disk that contains several billion bytes (gigabytes) of storage.


12/12

I. SOUND CARD

An expansion board that enables a computer to manipulate and output sounds. Sound

cards are necessary for nearly all CD-ROMs and have become commonplace on modern

personal computer. Sound cards enable the computer to output sound through speakersconnected to the board, to record sound input from a microphone connected to the

computer, and manipulate sound stored on a disk.

J. NETWORKING

In information technology, networking is the construction, design, and use of a network,

including the physical (cabling, hub, bridge, switch, router, and so forth), the selectionand use of telecommunication protocol and computer software for using and managing

the network, and the establishment of operation policies and procedures related to the

network. . Computer networking is the engineering discipline concerned with the

communication between computer systems or devices. A computer network is any set of

computers or devices connected to each other with the ability to exchange data.
