| Network Operating System (NOS) | Distributed Operating System (DOS) |
|---|---|
| A network operating system (NOS) is a computer operating system that is designed primarily to support workstation, personal computer, and, in some instances,older terminal that are connected on a local area network. | A distributed operating system is an ordinary centralized operating system but runs on multiple independent CPUs. Each computer runs as the part of global distributed OS. |
| Environment users are aware of the existence of multiple machines being used concurrently. | Users are not aware of multiplicity of machines. The operating system provides a single system image to its users. |
| They are not fault tolerant. Sometimes the Performance is badly affected if certain part of the hardware starts malfunctioning. | It is more reliable or fault tolerant i.e distributed operating system performs even in the partial failures. |
| Remote resources are accessed by either logging into the desired remote machine or transferring data from the remote machine to user's own machines. | Users access remote resources in the same manner as they access local resources |
| Examples : Windows NT, 2000, XP, Sun Solaris, Novell's Netware | Examples : Amoeba, UNIX, V, AEGIS |
