The main processing unit in a computer is the Central Processing Unit.

   The processor is called the central processing unit (CPU). It is also the central part of any computer. It has the Arithmetic and Logic Unit ALU and a control unit.

    The control unit loads programming instructions from a software file on the disk into the main memory (RAM). Then the ALU executes them in memory.  The results of computations are stored in the memory. Thus this sequence continues until all instructions are executed. The updated data or results of computations are stored back onto disk as given in a program.
 
   In case of errors like divide by 0, exceptions (errors) are reported and the program halts. The ALU executes instructions in binary number system. It does logical and arithmetic computations.

   A CPU has ALU, clock, Control Unit, a data bus, an address bus, input ports and output ports. Input and output ports are used to connect to input and output devices like keyboard, mouse, modem, gaming devices, USB devices etc.

    The address lines are used by ALU unit to access data in main memory. The data lines are used to get the data from main memory into the ALU registers and store the results back into the main memory. The clock gives digital pulses to the CPU and its parts. All actions take place when clock gives the pulses. Clock is the driving force behind the progress of a computer. Of course, CPU runs with a DC power supply.

Central processing unit

-----------------------------------------------

Main work of processing unit is to control all works of CPU and Ram.

CPU is one of the most important part of any computer. Because CPU manage the work of computer, display, It's ram, Display and all drivers.

There is one important unit in CPU and that is Motherboard. Motherboard has all connections of our computer like Keyboards, mouse, drivers and other things.

CPU uses Binary program to understand the computer language and other components.

CPU has ALU clock, by which CPU can understand what we are getting command's.
