  of virtual machines.
• They are typically manufactured by large
  companies for large-scale computing purposes

  which the computer is completely encapsulated by
  the device it controls.
• Embedded systems perform pre-defined tasks that
  have very specific requirements.
• Real-time operating systems are embedded systems
  with certain time requirements

• It's a diverse group of operating systems with
  several major sub-categories including BSD, and
  Linux.
• Unix like operating systems run on a variety of
  computers but more frequently on server systems
  and in academic and engineering environments due
  to high stability for any kind of processing
