Relation between guest and host operating system?

Answer 1

A guest operating system is considered a third party application. This is when users are allowed to work within an operating system that is shared on a public or private platform. A host operating system is one that a primary user owns or runs. He or she can also turn their operating system into a shared application if desired.

Answer 2

A host operating system can host a number of guest operating systems. There is one host o/s on a machine and one or more guest o/s. A guest o/s gives the user the impression that it is a separate physical machine. A user will log into a guest system and be unaware that the machine is virtual and that there may be other virtual machines on the physical machine.
