Network attached storage (NAS) is a dedicated file storage device that connects to a network, allowing multiple users and devices to access and share data from a centralized location. NAS systems provide a convenient and efficient way to store, retrieve, and manage files over a network, offering benefits such as data redundancy, backup capabilities, and easy scalability. They are commonly used in both home and business environments to enhance data accessibility, improve collaboration, and support data protection strategies by enabling centralized management of storage resources.
