COMPUTER - STRUCTURE

Various computer components, namely Hardware and Software of process materials that is formed by mutual coordination | All his parts (Hardwares) among themselves, by binding to each other's computer infrastructure, and process materials (Softwares) is carried out every task assigned to them by spares |

Computer used to make the major parts (Hardwares) as follows: -

1) Central Logistics (CPU -Central Processing Unit, Processor):
This microprocessor also says it is a part of the computer | All instructions specified by the user on the same microprocessor is done, the processor consists of three main sections, CU- Control Unit, ALU- Arithamtik and Logikl unit, and the MU- Memory Unit | The control unit controls the whole process and act on the instructions of the ALU or distributes MU, then sends them on to the results | It is also called the brain of the computer | Their performance kHz, MHz and GHz are measured in addicted |
Functioning of the processor depending on the bit is in the amount, such as 8-bit, 16-bit, 32-bit and 64-bit. Every two bit values ​​(00 or 01 or 10 or 11) to 232 in the 32-bit values. 32-bit processors up to 232 at a time, are able to act on data. The more bits in a processor will be as powerful as their functional ability and accuracy. 32-bit processor and 32-bit operating systems and applications with a capacity of less than the 32-bit processor can only work 64-bit operating systems and applications on the capacity can not act. While 64-bit processors and 32-bit operating systems and applications with a capacity of less can act on.

2) random access memory (RAM-Random Access Memory):
RAM is the temporary memory of the computer, the computer consists of the primary storage device | They have direct contact with the CPU, users have filled in the information and instructions from the operating system RAM comes in first, then any information CPU RAM takes Jrurtanusar, and again after the execution: RAM sends to , from which the operating system is assimilated | RAM memory is fleeting, unless the computer is in the power flows, RAM memory only lasts as soon as the current fragmented, RAM memory is destroyed as a result of the information in it is lost | Their capacity kg byte, megabyte and are measured in Gigabait accustomed |

3) the main system board (Main \ System \ Mother Board):
It is known by many names including, motherboard, and Manboard Sistmboard The trend is more, they are often called Planner | All other parts which are a type Srkitboard under a special system of indirect or overt remain fused together, making frequent mutual coordination and dialogue between all the components remains | Microprocessor, RAM, chipsets, graphics controllers, other input-output controllers are on the motherboard, allowing only Sthapity | Their performance measuring unit FSB (Front Side Bus) is |
4) Anmyika (HDD -Hard Disk):
These are the computer's permanent memory | The information is installed on them forever remain | These computers are a secondary storage device | RAM is much higher than their capacity, and they are able to collect a lot of information | These are not fleeting, like RAM, and even after the power is turned off on these communications, the information remains protected | The information is stored on these indelible, they only fade when users want to erase them himself | The motherboard's IDE (ATA) or SATA controllers are attached | Megabyte capacities, Gigabait, terabytes, is measured in Pikabait accustomed | It therefore remains permanently in a computer document exchanges typically by removing them from a computer to another computer is not put in |

5) The compact disk drive (CD \ DVD Rom - Compact \ Video Disc Drive):
Unlike the compact disc to the hard disk is easily removed and are worth easily be moved from place to place can bring the documents are easily exchanged |

6) floppy (FDD - Floppy Disk Drive):


7) frontend device / display (Monitor):
8) Keyboard instrument (Keyboard):
