Component-Computer Components.
Computers 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 disk, etc..
• Monitor / Screen Monitor is a means to show what we type on the keyboard board after processed by the processor. Monitors are also called visual display unit (VDU).
• Case Unit is a place of all computer equipment, whether it was the motherboard, cards, other peripherals and Procesing Central Unit (CPU). Casing of this unit is also called the System Unit. Procesing
• Central Unit (CPU) is one of the most important computer, because the type of processor also determines the computer type. Whether or not a computer, type of computer, computer prices, is determined primarily by the type of computer processor prosesornya.Semakin sophisticated, the ability to be better and usually more expensive price.
2. Software (software), is a computer program that allows you to run a job according to the desired. The program is written with 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 the devices installed on the computer so that each can communicate with each other. Without the computer operating system can not function at all.
• Utility programs, like Norton Utility, Scandisk, PC Tools, dll.Program utility functions to assist or mengisikekurangan / weaknesses of the operating system, such as PC Tools can do the format commands as DOS, but PC Tools keterang and able to give a good animation in the process of formatting. Files that have been deleted by DOS can not be returned again but with the help of this program can be done.
• Application programs, such as GL, MYOB, Payroll, etc.. Is a special program to do a particular job, such as programs on a company's payroll. So this program is only used by the financial part can not be used by other departments. This application program is usually made by a computer programmer in accordance with the demands / needs of a person / institution / company for purposes of interennya.
• Package Program, as Microsofr Office, Adobe fotoshop, macromedia studio, open office, etc. It is a program constructed 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 create a sales letter and so on.
• Programming Languages, PHP, ASP, dBase, Visual Basic, dll.Merupakan special software used to create computer programs, whether it's operating system, programs, etc. packages. This programming language is usually divided into 3 levels, namely;
o Low Level Language, the first generation programming language, this type of programming language is very difficult to understand because the machine language instructions. Usually only the manufacturer who understands it.
O Midle Level Language, is a middle-level programming language where instructions are approaching the use of everyday language, although it is still difficult to understand because many uses such as STO means singkatansingakatan store (for STORE) and MOV means move (an abbreviation of MOVE). The classified into these languages are Assembler, Fortran (Formula Translator).
o High Level Language, is a high-level language that has the cirri easily understood, because it uses everyday language, like BASIC, dBase, Visual Basic , VB.Net, etc..
3. Brainware (User), User is the personnel directly involved in the use of computers, such as systems analysts, programmers, operators, users, etc.. In large organizations, the problem is usually handled by computerized special section known as the EDP (Electronic Data Processing), or often called by EDP Department, headed by a Manager of EDP.
