Network attached storage (in short, NAS) describes storage devices that can be accessed over a computer network rather than being directly connected to the computer. NAS devices enable multiple computers to share the same storage space at once.

By adding a high-capacity NAS storage to a network, all of the devices in the network are able to simultaneously access and utilize this storage.In business situation, all users from marketing, sales, finance or production can access and store the company’s data on the same storage which is located on a centralized location. NAS also offers home user a simple solution to sharing files, music, photos, etc. You can put an entire family's digital photo collection on a NAS, and all family members can access the photos that are located on the same device.
