Networks are a key element of modern day organisations. It is little surprise that there is a whole field of computer science dedicated to how computers work within a network. The field is known as distributed computing and is an area of much research and development. Of course in order to facilitate distributed computing you need a NOS or network operating system. Most modern day operating systems are NOS.

The NOS can communicate with different machines in order to perform specific tasks. Depending on the task at hand will depend on what architecture will be used.
