What best describes Network Attached Storage (NAS) in a local area network?

• A. A storage device connected to a network that provides centralized storage for the LAN.
• B. A protocol for transferring files over the internet.
• C. A backup service operating in the cloud.
• D. Software that enables file sharing on servers.

Answer: (A)

Network Attached Storage is a dedicated storage device connected to a local network that provides centralized storage for the LAN’s devices. It sits on the network and serves files to clients using standard file-sharing protocols, so any authorized computer or device can access shared folders, backups, or media from one central place. This is different from a protocol for internet file transfer, from a cloud backup service, or from software that merely enables file sharing on servers—the NAS itself is the storage appliance on the network, typically with its own operating system, designed to be easily managed and expanded as storage needs grow.
