The Hidden Component
1-6
The hidden or "invisible" component of your computer is called software. What
we have been describing so far is called hardware. Software (or programs) are
the instructions which tell the hardware components what to do. They tell
the hardware things such as "print this character at the printer" or "display
this number on the screen" or "look at the keyboard to see if anything has
been typed."
Software is stored on disks in the disk drives, on the same kind of material
used
to make recording tapes. You can change software as easily as changing
a record.
