NAS stands for “Network Attached Storage.” Network Attached Storage (NAS) is a file-based storage system connected to a network that allows multiple users and devices to store, retrieve, and share files from a centralized device. Unlike traditional direct-attached storage (DAS), which is directly connected to a computer, NAS operates as an independent unit accessible over a local area network (LAN) or even remotely over the internet. By providing a single storage hub for a network, NAS streamlines data access, backup, and management, making it especially useful for businesses and home users who need flexible, scalable, and collaborative storage solutions.
