Network Operating System

A network operating system (NOS) is a computer operating system (OS) that is designed primarily to support workstations, personal computers and, in some instances, older terminals that are connected on a local area network (LAN). The software behind a NOS allows multiple devices within a network to communicate and share resources with each other.

The composition of hardware that typically uses a NOS includes a number of personal computers, a printer, a server and file server with a local network that connects them together. The role of the NOS is to then provide basic network services and features that support multiple input requests simultaneously in a multiuser environment.

Due to earlier versions of basic operating systems not being designed for network use, network operating systems emerged as a solution for single-user computers.

IS THERE ANYTHING THROUGH WHICH WATER CANNOT PASS BUT AIR PASSES???

IS  THERE ANYTHING THROUGH WHICH WATER CANNOT PASS BUT AIR PASSES??? YES, there is a substance that allows to water vapour to pass but not air. Read carefully Teflon is a substance that allow to pass to water vapour but not to the air, both are same and also nearly about same in form i.e. gases form…                 Point is that if we want to pass small molecules from anything it is possible because of small pores, holes and gaps present between it. Because of that small holes molecules are passed out. Large things are not pass through small small holes. water permeable image But in this case both the constituents are in the same form but one cannot pass and another can be pass from it, but why now we explain it.                 By stretching the substance that from we want to pass water or air small pores are formed millions...
