Computer Technological

1. What is Computers?
Actually, if a computer is, why modern society depends on the computer? Computers are the result of the progress of electronics and informatics technology that serves as a tool for writing, drawing, editing pictures or photos, create animation, scientific analysis program operates, simulation and for control equipment. Computers are used to form large enough to operate a program, now a small form with the ability to operate a variety of programs. Electronic equipment (hardware) and programs (software / software) has made a computer into a useful object. A computer that has only electronic equipment or software, it just will not work. With no two computers can then serve as a useful tool. Some people who hobby or the engineers, the computer can be used to develop the ability to control the production of machine tools or household appliances. By adding electronic circuits made, then the ordinary computer can be used to control industrial equipment and household. The tendency to control computer applications such as this with the support of IC chip technology has enabled people to make a useful little robots and robotic vehicles used in space missions.

2. Consists of whether a computer?
Personal computer (PC) consists of the central processing unit (CPU), keyboard, and monitor. CPU functions as a data processor, a keyboard as a data entry tool of letters and numbers or control commands to the computer to operate a particular data processing. Monitor is a tool viewer letters, numbers and images. The development of electronics and information technology has provided an enhancement to a personal computer such as a mouse (the computer controls the tool to operate the program commands are easy), modem (of the tools to change the form of digital data into voice data or vice versa, so the data from a computer can be communicated to other computers via telephone lines, radio communication station or earth), card games and sound (sound card), video card (video card), a television receiver card, a radio receiver card and ethernet card as well as various display devices / printer (Desk Jet, Buble jet, laser jet, plotter) and printing images translator tool (digitizer and scanner).

3. What are the contents of the CPU:
CPU (central processing unit) consists of:

a. Processor: be an brain is a computer system, organizing all operations that occur within the computer, the operating-displacement data opersi arithmetic and logic operation and control of input and output devices along with all resources (resource). Microprocessor having 5 times, 4-bit processor, 8-bit processor, 16-bit processor, 32-bit processor, and which today is the latest 64-bit processor. What is bit? For you who still wonder what the meaning of 64-bit can read the following explanation. If not, you can proceed to the next section. In the processor, the number of bits long claimed or the amount of data can be processed directly in one step. As 32-bit CPU, which means that the processor can process a 32-bit long instruction in one clock cycle. So the 64-bit processor is capable of CPU processing capacity instruction throughout the 64-bit in one clock output cycle.Data already been processed then the CPU will be included in memory *. By adding the data length capabilities that can be processed CPU, then indirectly also improve memory performance.

b. Mother Board: From the mother said we already know that the mother board motherboard is for assembling a computer. From the processor, memory, VGA card, Sound card, had disks, etc. everything connected with this mother board

c. VGA: (Video Graphics Adapter) as a channel to the monitor video out. At this moment desperately needed VGA VGA particularly large memory capacity such as 128 MB, 256 MB, 512 MB even has reached 1 GB. With a large memory capacity and speed clocknya very fast, it can be concluded that the components used are made with components the latest technologies. As for the part of the VGA

i. PCB (Printed Circuit Board)
On the video card, the basic colors used vary. Ranging from red, green and golden yellow.

There are two form factors are used. Most standard size with a height of about 99 mm (height bracket around 127 mm) wide and varied. Smaller size, with half height, known as form factor low-profile. This kind of video card is used as a mini PC. Occasionally found to operate with a Riser card.

ii. GPU / VPU This is the core of a video card. An IC (integrated circuit), his job as the CPU on a motherboard. He is dealing with 2D and 3D processes. Usually covered by a heatsink and fan.

iii. Memory
To distinguish the RAM / memory installed on the motherboard, more specifically referred to as video RAM. The similarity between the RAM with enough video RAM. But in practice, especially the video card RAM series of high-end, often using memory chips faster than the motherboard RAM.

iv. Bus Interface
For now, the options there are only two kinds of interfaces. Namely, AGP (Accelerated Graphics Port) and PCI Express. Previously had used the ISA and PCI slots for this video card.

v. Cooling System
Could have a video card that did not use a cooling fan, or even without a headsink? For the latest GPU, a thing almost impossible. With the clock is so fast, hot during operation can reach temperatures high enough. For information, the temperature on passive headsink (no fan) a GeForce FX5200 video card can achieve a range of 60 ° C. Can imagine the heat that can be produced by a video card high-end class

vi. Display Interface
Most video cards offer three types of interface ports: DVI, VGA and TV-Out. And others, only a minor combination of the three port. There are offers dual DVI, to be able to produce two views on the digital display. Some features include support for HDTV output (high-definition TV), or VIVO (video input Video output). Two of the latter, usually to include the additional functions on the video port.

d. Sound Card: sound cards are usually used to output sound. The data have been processed by the processor will be longer if the sound card to be made and amplified audio signal to be connected to the speakers.

e. Memory: Random Access Memory (English: Random access memory, RAM) is a type of computer storage whose contents can be accessed in random order. This is in contrast to sequential memory devices, such as magnetic tapes, disks and drums, in which the mechanical movement of the storage media to force the computer to access data sequentially. Usually RAM can be written and read, as opposed to memory-read-only (read-only-memory, ROM), RAM is usually used for primary storage (main memory) for use in computer and change the information actively, although some tools to use several types RAM to provide a secondary storage of long-term.

f. Disk: Hard disk is the only data on the computer peyimpanan. All programs, documents, music, videos etc. are stored in the hard disk. The process of storing data on your hard disk using ultraviolet sina.

g. CD-ROM or DVD-ROM: use light to a CD or DVD memuta suitable type of drive used.

h. Flopy Drive: before there was a CD-RW and types of memory bias taken anywhere, the floppy drive is very useful to carry data or files of other kekomputer. But after the CD-RW and memory such as Flash disks, MMC, etc. use the floppy drive appears to be reduced.

i. Suplay Power: Inside the CPU using the type Switching PS. Voltage issued by PS berpariasi ranging from 3.3 volts, 5 volts and 12 volts.

4. How do computer working?
Computer briefly worked in the following way:
Data entered by the user's computer via the keyboard (letters and numbers) or the mouse and scanner (graphic data / image) to the CPU. The data submitted to the software application to be processed in the processor and displayed on the screen. When assessed what appears on the screen is in conformity with earlier computer user desires, then the user will tell the computer to store his work in the storage media (floppy or hard drive) or ordering a computer to print through a printer.
In the CPU, there is a data communication process data submitted to the application program immediately forwarded to the operating system programs. By the operating system programs, data is converted into machine language understood by the electronic equipment contained in the computer so the screen can show what the last user or computer can communicate with the printing device (printer) and ordered the printer to print files desired user.
