On a Unix system, a terminal is a character-based device that one uses to communicate with the Unix system. In old-school days, this was done over a serial line (e.g. RS232 or RS422) directly or through a terminal server, and the devices used an ASCII protocol for controlling font styles like bold, blink, underline, and character placement. A common one was a Digital VT100. (Ever seen the command "setenv TERM vt100" and wondered what it did?)
Nowadays, we still use the word "terminal" to refer to a character-based interface, but instead of connecting to a real serial port (a TTY, or teletype, interface), we connect to a virtual one (a pseudo-TTY interface). We do this using an application, and in the case of OS X this application is called Terminal, and it resides in /Applications/Utilities. On an X11 system the terminal application is typically called xterm.
Man... does that take me back. Used to order parts for a car dealership that I worked for, when I was knee high to a horney toad, over one of those things.
Makes you love OSX.
