COMPONENT - A COMPONENT IN A COMPUTER SYSTEM IS DIVIDED 3 , WHICH CAN NOT BE SEPARATED AS FOLLOWS:

Components of Computer

• Processing Device

• Input and Output

Device

• Storage Device

• Operating System

• Application Program

• Language Program

CPU ( Central Processing Unit ) role for referral

process , implementing and counting attenuate

passage information computer system .

1 . Hardware computerThe device that we can see and we can touch it

physical , such as the input device , processing device

, and output devices . This equipment is generally quite

sophisticated . He can work on the orders available to

it , which is also called the instruction set

• Processing Device

1.input DeviceInput Device is a computer hardware serves as a tool to

enter data or commands into a computer

2 . output DeviceOutput Device is a computer hardware function to display

the output as a result data processing . Output can be either

hard - copy ( to paper ) , soft - copy ( to the monitor ) , or in

the form of sound .

2 . external StorageHardware to perform a write operation , reading and storage of data, outside the main components , namely :

• Floppy Disk• Hard Disk• CD Room• DVD

STORAGE DEVICE

1 . internal StorageRAM ( Random Access Memory )

To save our program if for temporarily . Can be accessed randomly( can filled written , drawn , or removed it )

ROM ( Read Only Memory )Read-only memory and is useful as a provider of information at the time of the first computer turned on.Can only be read , can not fill something into the ROM

2 Software computerThe series of procedures and documentation program resolve the problem that

the desired function . Constitute electronic data stored by a computer in such

a way that itself , the stored data can be either a program or instruction

which will be executed by the command , as well as records required by the

computer to run the command executable .

• Operating SystemThe operating system is the operating system or program base on a

computer that connects users with component computer hardware

associated software with program implementation and coordination of the

activitycomputer systems . There are several kinds of operating systems are:

Linux

Windows

Mac OS

That is a computer program that is ready for use or also

called ready-made program . The program package used for general

business applications , specific applications in the field of

industrial applications to improve organizational productivity

or productivity applications for companies and individuals .

example :

o Microsoft Word

o Microsoft Excel

o CorelDraw X4

o etc.

• Application Program

Language program or programming language is language used by humans to communicate

with the computer , because the computer has its own language then the computer will not

respond other than to use Language Programming , such as : a computer language that

used to write the program instructions for performing any work that is done by programmers ,

such as :

visual Basic

turbo pascal

Delphi

Brainware is a person who operates a computer ,

Because if there is no person who operates it will not be

used .

• Language Program
