            Palmtops  are  small  computers  that  literally  fit  in  your  palm.  Compared  to  full-
            size  computers, palmtops  are  severely  limited  in  functionality.   However,  they
            are practical for certain functions, such as phone books and calendars. They are
            commonly known as Personal Digital Assistants (PDAs). Because of their small
            size, most palmtop computers do not include disk drives. Palmtops have small
            keyboards or specialised keypads tailored to specific industries. Palmtops use pens
            and keyboards to input data. Figure 2.8 shows different palmtops.
