Hardware Problems
• • • • Understanding the hardware
Computer hardware is the physical part of a computer or system equipment used to perform computer functions. Development of electronic technology of the most rapidly and widely used in many fields in completing the work or to get information is nothing but the computer. Development of the computer is caused by the development of the microprocessor (processor) as the brain in dealing with the whole of the working computer.
In summary then the computer system consists of three main parts, namely:
A. CPU (Central Processing Unit) / Processor
2. Memory (RAM and ROM)
3. Input / Output
• •Mother Board
• Definition of Motherboard
Mother Board is a board / mother board or a board game where all the devices installed starting from the processor, memory, expansion slots, etc.. Main board is not less important to the processor. If we let in humans, the Main board is a series of blood vessels and nerves at the computer. Main board is not good, will not result in maximal performance of other peripherals. Therefore, the selection of an appropriate main board will greatly affect computer performance.
• How a Motherboard
In computer systems, peripherals, peripherals connected to each other on the main board and can continue instruction through channels on the board. Throughout the connected peripherals will be a complete computer system. While the main board functions in general is to channel the flow of input and data flows needed in the course of the process on the computer.
• North bridge and South bridge
The main chips on the main board there are two, namely the North bridge and South bridge. North bridge is the bridging function of the flow of data around main memory and processor power management and organize work. While the work function of South bridge is set such peripheral peripheral-IDE Controller, PCI bus, AGP, and the function I / O other.
• BIOS
In some main board chips EPROM which contains the basic operating system BIOS (Basic Input / Output System). This BIOS function is to conduct Hardware Bootstrap and Initialization at boot time.
• I / O Ports
I / O (Input / Output) ports are part of the main board to interact with the user via the media peripheral I / O such as keyboard, mouse, printer, and so forth. Most motherboards today have always had an interface PS / 2, USB, LPT, PCI, and Serial. All these ports are chose characteristics and functions of its own. The point is to allow a user to interact with the computer in doing such jobs.
That must be considered in selecting or assembling Mother Board is that every motherboard has different specifications for each brand or type, among others:
A. Each motherboard has a pair with a particular processor, the type of socket or slot is available to the processor.
2. Motherboard ability to be in the up-grade to the number of processor speed. Motherboards are generally able to up-grade to replace the processor. Information on this is very important to purchase a motherboard with consideration to be on the up-grade.
3. RAM memory capacity that can be installed on the motherboard of the larger memory capacity provided more favorable.
4. Slots available for each type of RAM, for example, how many slots are provided for EDO RAM, SD RAM, etc..
5. Setting the motherboard BIOS (software) or a jumper setting.
6. The number of slots for PCI and ISA. Slots are very useful for adding peripherals such as audio card.
7. Does the motherboard support for the VGA card for AGP, AGP support will be more profitable to stock if desired improved graphics capabilities of the computer by installing an AGP card.
8. Bus speed up to speed for how much memory (66, 100, 133, 200, 400 Mhz)
9. Is the VGA card and audio card is on board or not.
10. Power Supply for ATX Mother Board or Baby AT or AT. Several types of slot or socket for the processor include:
a. Slot 1
Mother Board is created to support Processor P-III and Celeron.
b. Slot 2
The motherboard is designed to support the P-II Processor and Xeon 9.
c. Socket 7
The motherboard is designed to support the AMD K6-2 processor, AMD K6-3 and Cyrix M-II and Pentium MMX.
d. Slot A
The motherboard is designed to support AMD Athlon, AMD Thunder bird.
e. Socket A
The motherboard is designed to support the AMD Athlon and AMD Duron.
f. Socket 370
The motherboard is designed to support Intel Pentium-III (Tualatin and Coppermine) / Celeron TM
g. Socket 8
Motherboards are made to support Pentium II and Pentium-Pro.
h. Socket 423
Motherboards are made to support Pentium-IV.
Central Processing Unit / Processor .....
• • • • Definition Processor
The main part of the computer because the processor serves to regulate all activities that exist on the computer. Speed ​​of the processor unit is MHz (Mega Hertz) or GHz (1000 megahertz), where the greater the value the faster the process of execution on the computer. Processor can we as the brain of the computer analogy. Hardware functions to do all kinds of processes in a computer system. So that the processor will determine the speed and performance of computer systems.
