DOS is a single user/single tasking system, hence the need for work 
arounds like TSRs to keep many programs running simultaneously.

Unix on the other hand is multitasked, and you can have as many programs 
as you want running in the background.  Just append & to the end of the 
command when you run it at the command line:

eg: netscape & will run netscape in the background.
or, if the program is already running, then Ctrl+Z to suspend and bg to 
send it to background.

Oh, yeah, last point.  Processes are memory resident, programs are just 
algorithms on disk.
