What do I need to set up a NAS?

-->

Network Attached Storage (NAS) is essentially a device that connects hard drive storage to your home or small business network and allows that data to be accessed by other computers and devices connected to that network.

You need to have a network router to create a local area network (or LAN) and a computer. The NAS will typically connect to the router via wired Ethernet connection, and then be visible by your computer. At that point, you can run any software set-up that's required (or added software, such as for automatically backing up your computer).

While most NAS devices require an Ethernet connection to your network router, some models offer built-in Wi-Fi wireless connectivity and don't need to be physically connected to a router.

While some NAS devices come with software that needs to be installed on every computer on your network in order for them to access the storage device, many NAS devices don't need any complicated software tweaks. Just connect the NAS device to your network, power it up, and your connected PCs, Macs, and mobile devices will see the NAS on the network and be able to access its files and features.
