Network Attached Storage (NAS) devices are dedicated file-level computer data storage servers connected to a network that provide data access to a heterogeneous group of clients. They are designed to be simple, scalable, and cost-effective solutions for storing, sharing, and managing digital assets in small and medium-sized businesses (SMBs), enterprises, and homes. NAS devices typically run on standard operating systems such as Linux or Unix and use network protocols like NFS, SMB/CIFS, AFP, or FTP to provide access to files over Ethernet networks. They offer features like redundancy, backup, and remote access, making them ideal for centralizing data storage and sharing across multiple devices and users. NAS devices are a key component of modern digital infrastructures, enabling collaboration, productivity, and security for various applications such as media streaming, surveillance, virtualization, and cloud computing.
