Functions and Understanding Computer Hardware

Computer Hardware (Hardware and Functions) -If earlier merahitam discusses thenotion of computer then this time will be continued in explanation of computer hardware(hardware) are all parts of a computer in their physical forms, and distinguished from the data that is in it or who operate in it , and distinguished by the software (software) that provides instructions for the hardware to accomplish its task. The boundaries between hardware and software will be a little blurry when we speak aboutfirmware, becausefirmware is software that is "built" into the hardware. Firmware is an area of computer science and computer engineering, are rarely recognized by the public. A typical computer personal computer (PC) in the form ofa desktopor tower case which consists of the following:
1. Processor
Processor is also called the brain of the computer, the better type of processor it is more expensive computer, the processor is referred to as the core of the computer. Processor function is to process all computer activities performed, the requested user.
2. Motherboard(motherboard)
is the circuit board where a variety of interconnected electronic components such as PC or Macintosh and mobo.Motherboard commonly abbreviated words that were encountered in the market today is the property of a PC motherboard that was first created with a base in order to fit the specifications of the IBM PC .
3. Chipset
components on the motherboard that this one mostly consists of two chips, north bridge and south bridge.
The main functions of the chipset is to regulate the flow of data between components installed on the motherboard. Two chipset which is usually on the motherboard itself has a different task from one another.
A chip on the north bridge function to regulate the flow of data to and from the processor, AGP bus, and the system's main memory. Meanwhile, the south bridge chip manages the flow of data from the input device outputs, PCI bus interface hard disk and floppy, and other external devices. Because the north bridge chip is more vital than the south bridge works, I wonder if the chip is mounted with heatsink, fan, or a combination of the heatsink and fan by the manufacturer.

4. AGP
stands for Accelerated Graphics Port. Its function is to distribute the data from the CPU to the graphics card without having to go through the main memory, thus the data processing can be accelerated graphics. Another advantage is the ability to AGP texture maps execute directly from main memory. Come with different flavors, most current motherboards include AGP 4X bus who works at a frequency of 266MHz. For now, the AGP port is used for installing a new graphics card is actually faster than using the PCI bus. However, some of the latest motherboards already include Pro AGP port that can be fitted either 4X AGP-based graphics card or AGP Pro based own
5. Memory socket
socket is the place to put the memory on the motherboard. The memory sockets have different forms for different types of memory. Most motherboards have slots as much as 3 or 4 pieces, depending on the chipset used. For memory SDRAM, DIMM sockets must-have is a 168 pin socket, while the memory type DDR, the socket is installed for the 184 pin socket.
6. The processor socket
is a place to put the processor. If antiquity, there are other options besides the system of slot socket system. However, after the era PentiumIII second generation, slot type is then abandoned because of the cost of production is more expensive than using a socket. For business this processor socket, choose a motherboard with processor socket right. Socket 370 for Intel PentiumIII and Celeron processors, Socket A for AMD Athlon and Duron processors, as well as 423/478 socket for Pentium4 processors.
7. CMOS
stands for Complementary Metal Oxide Semiconductor. From the shape is visible, it is a component in the form of IC (integrated circuit) that functions to accommodate the BIOS settings and can retain its settings for battery mendayainya still good.
8. Socket Power Supply (power supply, fan)
function is to supply power to all the components connected to the motherboard.9. Connector Casing Serves to connect button / switch and indicator on the chassis to the motherboard. Motherboards based on Pentium 4, also included an additional connector port is 12 volts so that the processor can work.10. Parallel Port For Connecting Printer11. USB port for connecting a device that supports Usb, such as: flash, mouse and keyboard USB, External hard drive, data cable, and other devices
