What type of storage allows for multiple machines to share storage over a network and allows the centralization of data?*1 pointRAMNASBlu-raySSD

Break Down the Problem

1. Identify the key features of the storage options given.
2. Compare these features with the requirements mentioned in the question: "multiple machines to share storage over a network" and "centralization of data".

Relevant Concepts

1. RAM (Random Access Memory): Used for temporary data storage in machines, not suitable for sharing over networks.
2. NAS (Network Attached Storage): A storage device connected to a network that allows multiple users and devices to access data centrally.
3. Blu-ray: A physical medium for storing data, not designed for network sharing.
4. SSD (Solid State Drive): A type of storage device that offers fast data access but is typically used for single machine storage.

Analysis and Detail

1. Compare NAS with RAM: RAM is volatile and not shared; hence unsuitable.
2. Compare NAS with Blu-ray and SSD: Blu-ray is unsuitable for networking; an SSD, while fast, does not provide centralized data over a network.
3. Focus on NAS: It is specifically designed for multiple machines to access shared storage over network protocols.

Verify and Summarize

• Among the options, NAS clearly supports both network sharing and centralization of data.

Final Answer

The correct answer is NAS (Network Attached Storage).
