                 Draw and colour your favourite input device on chart paper. Also write its use.




              Processing Device

              The Central Processing Unit (CPU) is the hardware processing
              device that works on input data and sends the result to the output

              devices. The CPU is a chip which is placed inside the CPU box.
              CPU is also called the brain of a computer as it is responsible for
              all the work done. A CPU is further divided into three parts: ALU,             CPU              CPU box

              CU and MU.                                                                              CPU

              Arithmetic Logic Unit (ALU)                                                         Control Unit

              ALU does all the arithmetic calculations like addition, subtraction,
              multiplication, division, etc. It also does comparisons like greater            Arithmetic Logic Unit
              than, less than, equal to, etc.

              Control Unit (CU)                                                                   Memory Unit

              CU coordinates and controls all the parts of the CPU. The CU gets the data and instructions
              from the memory unit and passes them to the ALU in a step by step manner.

              Memory Unit (MU)

              The CPU also has a memory like human beings. The MU stores the data and instructions that you
              give to the computer along with the results of the processing. Memory Unit is known by different
              names like Internal storage unit, main memory or primary storage or RAM.

              Output Devices

              The result we get after processing is called output. The devices which help us get these results
              or outputs are called output devices.

              Now let us learn about more output devices.

                                    Printer

                                    A printer produces a hard copy (printouts) from a computer usually onto
                                    a paper.



              Speakers

              Speakers are used to listen to music, voice and sound on a computer.
