What is the difference between distributed and modern operating systems?

Answer

A modern operating system functions on and within a specific computer although it may collect, use or deliver data outside of its self. A distributed system utilises computing power from two or more computer systems. A task may be performed within this computer or on another within the group, or may be split such that portions of a smaller task can be performed on different computers. Remote computing uses messages over a network to request tasks to be undertaken. These messages pass the necessary parameters for the task and on completion messages return the results. Its as if the computers email each other with a request and an answer.

The distinction "modern operating system" versus "distributed operating system" makes little sense, though. Distributed operating systems are in many ways more complex and sophisitcated. With high-end computing demands, distributed operating systems continue to be a very active field of research and development; in many ways making these systems more modern than the mainstream operating systems. Those, instead of "modern operating" system, might better be called "desktop operating system," "single machine operating system," or "mainstream operating system."

Finally, it should be noted that almost any current operating system is a mix between a distributed and a single-machine operating system, including some of the features required for remoting.
