Which of the following statements about Network-Attached Storage is true?

Network-Attached Storage (NAS) is designed to provide a centralized storage solution that allows multiple users and devices to access data simultaneously over a network. This characteristic is one of the key features that distinguishes NAS from traditional storage solutions, which often cater to a single user or a direct connection to a local machine. In a NAS setup, data can be shared efficiently across various platforms and devices, enhancing collaboration and resource accessibility.

The ability to serve multiple users and devices makes NAS particularly beneficial in environments such as offices, schools, and home networks, where the need for shared access to files and data is common. By providing centralized management of storage, NAS solutions also simplify data backup and retrieval processes, making them more convenient for users compared to traditional storage methods.

The other options do not accurately reflect the characteristics of NAS. The cost may vary, but it is not definitively more expensive than traditional storage options. NAS systems are specifically designed for multiple concurrent users rather than restricting access to one user at a time. Additionally, a NAS setup is often straightforward to implement, typically not requiring an overly complex network configuration compared to some other storage technologies.
