External hard drives are devices to store your files, from documents down to movies. But there is a limitation to it: can be used by one computer at a time. Therefore if you'd like your hard drive to be a repository of files from multiple computers connected in a network, without using a server (just to complicate things like in a business set-up), find a network hard drive from your favorite computer stores!
Network-attached Storage (NAS) drives are easy to use. Just connect it to your usual router using the ethernet cable then all the computers connected to the router (whether wired or wireless) can access and save information to the NAS drive! Technology is making our lives easier isn't it? , only if we use it correctly.
