A home network is basically two or more home PCs that are connected to each other by a common internet connection making it easier to share files, stream data or even play games between such devices. PCs connected via a wireless network offer the convenience of mobility and are recommended over wired connections. One of the biggest advantages of a home network is that you can print from any device on the network simply by connecting one of the devices to a printer. Home groups are easy to set up in Windows 8 and help you share libraries and printers
