Homegroup is a feature that allows shared disk access, shared printer access and shared scanner access among all computers and users (typically 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. The Windows HomeGroup feature was introduced with Microsoft Windows 7 in order to simplify file sharing in residences.
