The full-form of NAS is ” Network Attached Storage .” This is a typical computer that stores data using internal and external hard drives. If a computer is connected to a network , then it can share the data in its connected hard drives which are connected with other systems of the network. By the way, it allows multiple computers to send data back and forth, while it is required that each computer share its files individually. This is the reason that if a computer is turned off or disconnected from the network, then its files are not available for other systems.
Using NAS, computers can store and access data from a centralized storage location. Here, in exchange for each computer sharing its files, the shared data is stored here in a single NAS server. It provides a simpler and more reliable way to share files in a network.
Once a NAS server is connected to a network (typically via Ethernet), it can then be configured to share files with multiple computers in the same network. In this, the administrator can either allow access to all systems or can limit the access to a limited number of authenticated machines only.
NAS servers typically have a large number of multiple hard drives , which provide a large amount of shared disk space for connected systems to save data. They are often used in business networks, but now it is being used in home networks too much. Since NAS uses a centralized storage device, this can be a simple way for family members who want to share and backup their data .
