                     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.
