Which type of storage uses shared network access for multiple devices?

1. SAN

2. DAS

3. NAS

4. All of the above

The correct answer is: NAS

The correct choice is NAS, which stands for Network Attached Storage. This type of storage allows multiple devices to access shared data over a network, making it ideal for collaboration and data sharing among users and systems. NAS systems are specifically designed to facilitate this type of connectivity, providing storage that can be easily accessed by various clients on the same network. Large organizations often use NAS for centralized file storage and sharing, as it simplifies data management and enhances accessibility across different devices. The advantage of NAS is its user-friendly interface and the ability to support file sharing protocols, such as NFS and SMB/CIFS, enabling various operating systems to retrieve and store files easily. While SAN (Storage Area Network) also provides shared access to storage, it operates at a different level, dealing with block-level storage and typically requiring dedicated hardware and a more complex setup. DAS (Direct Attached Storage), on the other hand, connects directly to a single computer or server and does not offer shared access over a network. Therefore, NAS is distinctly characterized by its focus on shared access for multiple devices via a network, making it the appropriate answer here.
