NAS operating systems' functions are focused on file storage, file transfer, user access and keeping NAS devices running well. NAS units usually don't have a keyboard or display, and are controlled and configured over the network, often using a browser.

But NAS is not featured with a full computer operating system but a cut-down OS. NAS is composed with a CPU, memory and OS. It may contain more than one network storage drive arranging into logical, redundant storage containers or RAID. NAS is especially designed as a computer appliance specializing in serving files either by its hardware, software, or configuration. NAS devices are ideal for providing multiple authorized network users remote access to vast files and data storage/sharing from a centralized location.
