Which type of storage connects to a computer but is not shared over a network?

Direct-attached storage (DAS) is the correct answer because it refers to storage devices that are directly connected to a computer or server without any intermediary network. This type of storage typically includes hard drives or solid-state drives that connect via interfaces like USB, SATA, or SCSI. Since DAS is not shared over a network, it is accessible only by the device to which it is connected, making it suitable for individual users or small setups where centralized storage is not needed.

In contrast, other options like network-attached storage (NAS) and storage area networks (SAN) are designed specifically for sharing data across a network, providing access to multiple users or devices. Cloud storage, similarly, allows data to be accessed over the internet, thus also enabling sharing and remote access. These characteristics differentiate DAS from the other storage solutions mentioned, reinforcing the concept that direct-attached storage is intended for localized use.
