CPU

  
  The CPU is the brain of the computer. It is sometimes refered to simply as the processor or central processor,the CPU is where most calculations occur. In terms of computer power,the CPU is the most important element of a computer system. In large computers,CPUs require one or more printed circuit boards. In  personal computers and small workstations,the CPU is contained on a single chip called a microprocessor. 
  

 
 
                                            THE CLOCK
   This is a small but important part of the hardware. It's integrated in the CPU. It marks the rhythm of the processor. The faster the clock, the faster the computer. Modern processors have turbo technology:this is a system that raises the frequency if the processor is not too hot and lowers the frequency if the processor is too hot. The unit of the clock is the hertz (Hz). The clock is inside the processor.
