Line 3: ==Overview== A NAS concentrates dial-in and [[dial-out]] user communications. An access server may have a mixture of analog and digital interfaces and support hundreds of simultaneous users. A NAS consists of a [[communications processor]] that connects asynchronous devices to a [[LAN]] or [[Wide area network\|WAN]] through network and [[terminal emulation]] software. It performs both synchronous and asynchronous routing of supported protocols. The NAS is meant to act as a [[Gateway (telecommunications)\|gateway]] to guard access to a protected resource. This can be anything from a [[telephone]] [[Telecommunications network\|network]], to [[computer printer\|printers]], to the [[Internet]]. A [[Client (computing)\|client]] connects to the NAS. The NAS then connects to another resource asking whether the client's supplied [[credentials]] are valid. Based on that answer the NAS then allows or disallows access to the protected resource.
