            Desktop Computer


            A computer that we keep on a desk or a table is called a
            desktop computer. We can find them in offices, at homes,
            and in many other places.                                                   Desktop Computer

                  We can see many things around us, some of them are natural and some of them are
                 man-made.
                 Computer is a machine that can do many kinds of work.
                  Machines are man-made things that save our time and make our work easier.
                  Computers  can  store  a  lot  of  information  and  never  forget  it,  but  man  may  not
                 remember many things stored in his brain.
                  Computers work very fast and can do many tasks at a time, whereas men work slowly
                 and can do only one task at a time.
                  Computers never get tired and can work for a long time, but men get tired and need
                 rest after working for some time.
                 Desktop, laptop, tablet and smartphone are different types of computers.
