Distributed Operating System Programs

A distributed operating system is a software over a collection of independent, networked, communicating, and physically separate computational nodes.Each individual nodes hold a specific software subset of the global aggregate operating system. Each subset is a composite of two distinct service provisioners. The first is a ubiquitous minimal kernel, or microkernel, that directly controls that node’s hardware. Second is a higher-level collection of system management components that coordinate the node's individual and collaborative activities.

     A distributed OS provides the essential services and functionality required of an OS, adding attributes and particular configurations to allow it to support additional requirements such as increased scale and availability. To a user, a distributed OS works in a manner similar to a single-node, monolithic operating system. That is, although it consists of multiple nodes, it appears to users and applications as a single-node. 

   It was one of my favorite subjects during my college days (it was also taught nicely by our course teacher). U get to learn many concepts and slightly u can also visualize how the current distributed operating systems work in background and tackle many difficulties and issues the OS faces.
