4. Introduction Computer consists of two parts: - hardware. - software. * The two parts are complementary to each other can not take advantage of the existence of one without the other. * Hardware are divided into a central unit and secondary devices. * The central unit is further divided into: - Processor (CPU). - core memory

5. Definition CPU Calling computer by the processor (CPU). What is the processor (CPU). Multi-processor. Development the processor.

6. Components of CPU The important components of CPU is : - CU (Control Unit): Function to search for information stored in RAM and determine what should be done through (ALU). - ALU ( Arithmetic Logic Unit ): Function to carry out orders issued by the (ALU). Operations control and calculation (such as collection(+), subtract(-), division(÷) and hit(×), and Boolean operations etc...

7. Stages of the work of CPU Read instructions from RAM. Decide what data needed to execute the instructions. Brings the data needed to implement those instructions. Do the instructions. Write the result in RAM. Begins with the following instructions.

8. CPU frequency Intended frequency of the processor. The unit of measurement speed of the processor: - Megahertz (MHz). - Gigahertz (GHz).

9. CPU Cooling Any piece of any electronic device you need a certain range of temperature within which to work, especially the processor. damage to the processor when the lack of proper temperature : 1. Shorten the life of the processor. 2. Slow down the work. 3. Cause errors in the accounts. 4. Cause the computer stops working repeatedly. 5. Restores a computer may restart itself for no reason. 6. Errors may occur in the hard disk. 7. Can hang the processor fully.

10. Conclusion about CPU Can have two processors in the computer and this requires several factor s, including : - to be available in the motherboard any occurrence of this potential slots for the processor. - to support the processor and operating system have this feature. But often not be fully double the increase.
