What does Network Attached Storage (NAS) provide?

1. Block-level access to storage

2. Shared storage that connects across the network

3. High-speed data transfer capabilities

4. Central management of storage devices

The correct answer is: Shared storage that connects across the network

Network Attached Storage (NAS) is designed to provide shared storage that connects across the network. This means that multiple users and devices can access the stored data simultaneously from different locations, facilitating file sharing and collaboration. NAS systems are typically configured to be user-friendly, with interfaces that allow easy setup and management of shared resources. The emphasis on network connectivity is crucial, as NAS operates using standard networking protocols, allowing for a wide range of devices to communicate with it, whether they are Windows, macOS, or Linux-based systems. This capability makes NAS particularly appealing for home users and businesses looking for cost-effective and efficient storage solutions. While options like block-level access are associated with other types of storage solutions such as SAN (Storage Area Network), NAS is inherently file-level storage, optimizing it for easy file sharing. Similarly, high-speed data transfer capabilities may vary based on the specific NAS hardware and network infrastructure used, but they are not the primary function of NAS. Central management of storage devices is more characteristic of SAN environments where administrators need to control multiple storage devices from a central console, rather than the more straightforward management approach commonly offered by NAS.
