Why each option
A Network Attached Storage (NAS) device is a dedicated file storage server that allows multiple clients and servers to access data over a standard IP network, like Ethernet.
While NAS uses an existing network, it is designed to be accessible by multiple servers/clients, not just a single server.
This describes Direct-Attached Storage (DAS), where storage is connected directly to a single server, not Network Attached Storage.
This describes a Storage Area Network (SAN), which uses dedicated channels (like Fibre Channel or iSCSI) to provide block-level storage to multiple servers.
NAS provides file-level data access over an existing network (typically TCP/IP Ethernet) to multiple networked clients and servers. It simplifies data sharing and collaboration by making storage available as network shares.
