Answer: C

Explanation:

A NAS is a Network Attached Storage device; typically a bunch of cheap hard disks, usually arranged in a Raid and consisting of either SAS (serial attached SCSI) or Sata disks just like the ones in most desktops.

A NAS is essentially a file server that connects to an Ethernet network and is configured with a TCP/IP address. A NAS supports Windows networking and works at the file level as opposedto a SAN (Storage Area Network) which works at the block level when dealing with data. You can access file shares on a NAS in the same way that you would access file shares on a file server.

A NAS is a much cheaper option than a SAN.
