operating system

Different Operating Systems on the Same Machine ?

It is possible to have more than one operating system available to be used on a machine.
Only one operating system is run at a time, though.
Examples:
VAX - VMS or Ultrix
IBM PCs - DOS, WIN95, or Linux

Operating Systems:

Most computers have a single operating system available.
Many operating systems are tailored for use on a specific machine with specific peripherals
Each operating system has its own command language
