Computers that we know when this is the result of the development of information technology, electronics and computer so that the origin of the large size and eating places, is now shaped by the ability of small. The progress of electronics components industry IC (integrated circuit) has encouraged the creation of various IC chip device that supports a variety of different needs and the creation of electronic products. The progress of electronics technology is not separate from the progress in knowledge and processing of semiconductor materials, especially silicon.

In the world of entertainment, has long been the world's children know the game means the game is controlled by a computer system. In the field of industry, the computer has been used to control the machinery of production with high accuracy (for example, CNC, a multipurpose machine in the metal industry) so that we can find a variety of metal products industry is varied and difficult to imagine when we done manually. Many machines in the garment industry are equipped with computer control, for example, a company can produce bodir hat hat embroidered with the image quality is uniform in the number of lots in a short time.

In trading companies such as department stores have used machines, cash registers (cash machine), with the engine control computer so that it can be controlled by the manager only works only from the room.

In the field of education, found other than as a tool of study, many of laboratory equipment equipped with computer equipment so that it can work more carefully and obstacles can be overcome obstacles human sense. From the field of education and research that make the equipment that produced a variety of useful research results that have not already used in many day-to-day life of many communities. In biotechnology, equipment culture has been equipped with a computer control to organize the work on the accuracy sterile space. Australian companies have developed robots for the purposes of this biotechnology.

Many recent vehicles have been equipped with computer systems that use the fuel can be arranged to a very efficient for a trip that far. Bus-bus passengers have been equipped with computer control systems and sophisticated sensors that bus ride is noticeably more secure.

Application of computer control that tercanggih found in the aircraft and space aircraft. To be able to overcome many obstacles and difficult nature done by a manual pilot, an aircraft can be automatically so that can fly safely at the destination.

Meaning Computer System

Together with our knowledge, the technology has developed so quickly, during the various changes occur certain the significantly on the views of the technology, however, are the essence of technology is still in the framework of reference. For example, in the days before 2000, the public still regard the computer is a machine that is usually located on a table where the table is a keyboard, monitor and CPU. Or, better known as the Personal Computer. Besides, people still distinguish between the computer and mobile phones, fax machines, video player, sound system, photocopy machines dlsb. However, here the device is more difficult to be distinguished. Let discussions our menajam more about the computer system is, of course it's good we first discuss what is meant by the system and the computer itself.

System

Actually what it is that system? In a simple system can be translated: A unit of interrelated elements that form a group in conducting a basic goals that are targeted.

As mentioned above, the system does not only involve a function or procedure only, but a unity of all matters involved to work closely with the desired good.

Computer

So, now what with the computer, whether a computer is? if only the computer that is frequently we see on the table for the office? Yes! That is one example.

Computer language derived from the Latin word from Computare, which means that the count (in the English language to compute). In general defenisi computer is an electronic device that can receive and process the data into information, run programs stored in memory, and can work automatically with certain rules.

We certainly agree, the computer does not understand human language. Then how can the human command understood by the computer? Meanwhile, the engine computer based on the work flow of electricity that is it.

This made a certain rule on how the human desire can be translated so that the machine can understand. The electronic machines can understand this command with some basic command of his own (instruction set).

Command to create a human through a computer program, which contains the instruction program that was set. So automatically through a program that has prepared the computer can understand what the are.

With the above, it is apparent that the computer can exist only as a calculator, notebooks, personal computers, and others. Computers are the results from the progress of electronics and informatics technology, which functions as a tool for writing, drawing, picture or photo editing, animation to create, operate, scientific analysis program, and to control the simulation equipment.

The first form of a computer big enough to run a program, now form a small program with the ability to operate diverse. Electronic equipment (hardware) and programs (software / software) has made a computer into useful objects. A computer that only have electronic equipment or software alone will not work. With no two computers can then work to become a useful tool.

Computers can also be developed to control the engine production equipment or household equipment. By adding a series of electronic buatannya, the usual computer can be used to control industrial equipment and household appliances. The tendency of the use of computers to control such as this with the support of IC chip technology has enabled people to make robots that are useful as a small robot vehicle used in space missions.

Computer System

Computer systems are elements related to activities by using a computer. Elements of the computer system consists of human beings (brainware), software (software), instruction set (instruction set) and hardware (hardware).

Thus, the component elements that are involved in a computer system. Of course, the hardware does not mean anything if no one from the other two (software and brainware). Simplest example, who will turn on the computer if there are no humans. Or will it run if the computer is no softwarenya.

The existence of the development of electronics and information technology has provided enhancements on a personal computer, such as:

• Mouse, a mechanical device to perform a job that is usually done by men. For example, do pengecatan car. This robot is equipped by machine or computer device both simple and complex, which is able to control the movement.
• Modem, the tools to change the form of digital data to voice data or vice versa so that data from a computer can be communicated to other computers through regular phone lines, radio communication earth station or
• Sound card, part of the computer components that form the card function to generate the sound.
• Video card, a tool to display information to the monitor screen.
• Card recipients television, equipment for the catcher television signals.
• Card recipients radio equipment to receive radio waves.
• Ethernet card, a tool for connecting with the computer network.
• Printer, printing equipment (desk jet, buble jet, laser jet, plotters)
• Tool interpreter image printing (Digitizer and scanners).
  

Computer and Information System

Computer systems and informatics have a very close relationship, and can not be separated with one another. As explained previously, information itself is a discipline which specifically concerns the processing of data with the symbolic use of automation machines or computers. Of course, the computer is here is the computer system itself.
