Network Attached Storage (NAS) refers to a specialized file-level data storage server connected to a computer network that provides data access to multiple clients simultaneously. It is designed to hold large amounts of digital information, such as documents, multimedia files, and databases. NAS devices are categorized under electronics and computing hardware, specifically within desktop computers and networking hardware. They provide an efficient and centralized solution for sharing, storing, and backing up data across a network without relying on individual computer systems or external drives. By allowing concurrent access to stored files, NAS enhances collaboration among users, simplifies data management, and ensures data availability and security. Its primary function is to serve as a dedicated storage device that can be accessed remotely over the network, providing seamless integration with various devices such as laptops, desktops, smartphones, and tablets.
