Home network
A home network or home area network (HAN) is a residential local area network (LAN) for communication between digital devices typically deployed in the home, usually a small number of personal computers and accessories, such as printers and mobile computing devices. An important function is the sharing ofInternet access, often a broadband service provisioned by fiber-to-the-home or via Cable Internet access,Digital Subscriber Line (DSL) or mobile broadband by Internet service providers (ISPs). If an ISP only provides one IP address, a router including network address translation (NAT), proxy server software and typically a network firewall, allows several computers to share the external IP address. The router function may be assumed by a PC with several network interfaces, but a dedicated router device is more common, often including a wireless accesspoint, providing WiFi access.
HOME GROUP
A home group is a feature that allows shared disk access, shared printer access and shared scanner access among all computers and users (typically all family members) in a home, in a similar fashion as in a small office workgroup, e.g., by means of distributed peer-to-peer networking (without a central server). Additionally, a home server may be added for increased functionality.A Windows HomeGroup is a new feature in Microsoft Windows 7 that simplifies file sharing. All users (typically all family members), except guest accounts, may access any shared library on any computer that is connected to the home group. Passwords are not required from the family members during logon. Instead, secure file sharing is possible by means of a temporary password that is used when adding a computer to the HomeGroup.
