Network Attached Storage (NAS) is a type of network storage system that saves data onto another
computer system attached to a group of computers through a network, or onto a special server attached to
the network.
In this case, a mainframe computer is usually linked to a number of other workstations.
The mainframe computer is used to save all the files, and the workstations can access the mainframe through special links.
Network-attached storage (NAS) is file-level computer data storage connected to a computer network
providing data access to heterogeneous clients.
