The computer consists of three main components that can not be separated, namely;1. Hardware (hardware), is the physical equipment of the computer that we can see and feel. This hardware consists of;
* Input / Output Devices (I / O Device) Consists of input and output devices, such as keyboards and printers.
* Storage Devices (storage device) is a medium for storing data such as floppy disks, hard disks, CD-I, flash disks, etc..
* Monitor / Screen Monitor is a means to showcase what we type on the keyboard board after being processed by the processor. Monitors are also called visual display unit (VDU).
*
Casing Unit is a place of all computer equipment, whether it's the
motherboard, cards, other peripherals and Central Procesing Unit (CPU).
Casing of this unit is also called the System Unit.
*
Central Procesing Unit (CPU) is one of the most important computer
parts, because the type of processor determines also the type of
computer. Whether or not a computer, type of computer, computer prices, are determined mainly by the type of processor. The more advanced computer processors, then the ability will get better and usually the price will be more expensive.2. Software (software), are computer programs that are useful to perform a job according to the desired. The program is written in a special language understood by computers. Software consists of several types, namely;
*
Operating System, such as DOS, Unix, Linux, Novell, OS / 2, Windows, is
software that serves to activate all devices installed on the computer
so that each can communicate with each other. Without any operating system then the computer can not function at all.
*
Utility Programs, such as Norton Utility, Scandisk, PC Tools,
dll.Program utility serves to assist or mengisikekurangan / weaknesses
of the operating system, such as PC Tools can make the format as a DOS
command, but PC Tools is able to provide keterang and good animation in
the process formatting. The file was deleted by DOS can not be restored again but with the aid program this can be done.
* Program applications, such as GL, MYOB, Payroll, etc.. Is a special program that perform a specific job, such as programs on a company payroll. Then this program is only used by the finance department alone can not be used by other departments. Typically
this application program created by a computer programmer in accordance
with the demands / needs of a person / institution / company for
purposes of interennya.
* Program Package,
such as Microsofr office, Adobe fotoshop, macromedia studio, open
office etc. It is a program that was structured so that can be used by
many people with various interests. Such as
MS-office, can be used by the finance department to create a bill, or
the administration to make the letter of offer and so forth.
*
Programming Languages, PHP, ASP, dBase, Visual Basic, dll.Merupakan
dedicated software used to create computer programs, whether it's
operating system, programs, etc. packages. This programming language is usually divided into three levels, namely;o
Low Level Language, the first-generation programming language,
programming language type is very difficult to understand because it
uses machine language instructions. Usually only the manufacturer who understands it.o
Midle Level Language, is a mid-level programming language where the
usage instructions already approaching everyday language, although it
is still difficult to understand because many uses such as STO
singkatansingakatan means to keep (an abbreviation of STORE) and MOV
means to move (an abbreviation of the MOVE). are classified into this language is Assembler, Fortran (Formula Translator).o
High Level Language, is a high-level languages that have a
characteristic is easy to understand, because it uses everyday
language, like BASIC, dBase, Visual Basic, VB.Net, etc..3. Brainware (User),Users
are personnel who are directly involved in the use of computers, such
as systems analysts, programmers, operators, users, etc.. In
an organization large enough, the problem is usually handled by
computerized special section known as the EDP (Electronic Data
Processing), or often referred to as EDP Department, headed by a
Manager of EDP.
