What is a Network-Attached Storage?
A unit of NAS is basically a self-contained computer that is connected to a network. Its single purpose is to provide file-based data storage for other devices within a network. Within the NAS units are operating systems and other software that enable storage functionality. There are also management procedures for these functionalities. NAS does not perform computing tasks, but users can run software in it. Also, a NAS lacks keyboard and display. It can only be configured and controlled through the network by connecting a browser to a network address. If you do not have NAS in your network, you can use the computer as a file server. A file server works the same as a NAS unit. The difference is a file server has a keyboard, display, and an operating system. This makes it possible to store data and run other tasks as well. However, NAS is preferred for storage because file servers are also being developed for other functions, such as e-mail and database services, among others.
