FILE               A file is a "place" where the computer sends or
                   receives information.

     In that sense, a printer is a file.  But so is your terminal.
     And so is information that you type in and save in a disk
     file called "MYFILE".

     When you save "MYFILE", the computer tucks it away in a safe
     place, usually on a disk.  When you want it again, you tell
     the computer to look for the file called "MYFILE".  Simple
     enough.  You and the computer have agreed on how to identify
     that file.  And unless you instruct it to look somewhere
     else, the computer will look for that file on a disk.

     If you created "MYFILE" you could also change its name.
     There are even ways of temporarily changing the name by which
     you and the computer agree to identify a device.

     Why would you do that?  Right now there's probably no reason
     in the world.  But later on you might find there are some
     very good reason for setting up temporary names for devices.
