NAS : 5GMM

Last updated on 

let's break down two potential components of your question:

  1. NAS (Network Attached Storage):
    • Definition: NAS refers to a type of dedicated file storage device connected to a network, typically through Ethernet or Wi-Fi. It allows multiple users and heterogeneous client devices to retrieve and store data in a centralized location. NAS devices can also provide additional features like RAID configurations, remote access, and backup functionalities.
    • Technical Details:
      • Protocols: NAS typically uses protocols such as NFS (Network File System) for UNIX-based systems and SMB/CIFS (Server Message Block/Common Internet File System) for Windows-based systems.
      • File Systems: NAS systems can utilize various file systems such as ext4, ZFS, or NTFS, depending on the specific NAS device and its configuration.
      • Redundancy: Many NAS devices support RAID configurations to provide redundancy and improve data reliability. RAID levels like RAID 0, RAID 1, RAID 5, and RAID 6 are commonly used.
      • Access Control: NAS devices often provide mechanisms for access control, allowing administrators to set permissions and restrictions on who can access specific files or directories.
