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. It operates independently of a computer, providing a centralized location for storing files, backups, and media. Users can access the stored data from various devices, such as laptops, smartphones, and tablets, making it convenient for both home and business use. NAS devices often come with built-in software for managing files, user permissions, and data security. They can support various file formats and protocols, ensuring compatibility with different operating systems. Additionally, many NAS systems offer features like remote access, data redundancy, and cloud integration for enhanced functionality.
