  1. Hardware

  2. Control Process Unit(CPU)

  3. Contents • Introduction • Definition CPU • Components of CPU • Stages of the work of CPU • CPU frequency • CPU Cooling • Conclusion about CPU

  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: • Shorten the life of the processor. • Slow down the work. • Cause errors in the accounts. • Cause the computer stops working repeatedly. • Restores a computer may restart itself for no reason. • Errors may occur in the hard disk. • Can hang the processor fully.

  10. Conclusion about CPU • Can have two processors in the computer and this requires several factors, 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.
