D ISK A TTACHMENT Network-attached storage (NAS) NAS protocols : They typically provide access to files using network file sharing protocols such as NFS, SMB/CIFS, or AFP. NFS and CIFS are common protocols NFS (network file system) for UNIX system CIFS (common internet file system) for windows system This two protocols is type of : Remote Procedure Call (RPC)

D ISK A TTACHMENT Characterize : NAS not provide just storage data but backing up and sharing files across your network. NAS as a convenient and easy method of sharing files among multiple pc’s computers NAS allows greater sharing of information especially between different operating systems such as Unix and Mac Advantages : faster data access , easier control, and simplementation

D ISK A TTACHMENT Characterize : NAS systems contain one or more hard disks, often arranged into logical, redundant storage containers or RAID arrays. NAS provides both storage and a file system. File System managed by NAS is easier to do than other storage access method like a Storage area network.
