Traditionally, data-centric equipment such as computers and media players have been the primary tenants of a home network. However, due to the lowering cost of computing and the ubiquity of smartphone usage, many traditionally non-networked home equipment categories now include new variants capable of control or remote monitoring through an app on a smartphone. Newer startups and established home equipment manufacturers alike have begun to offer these products as part of a "Smart" or "Intelligent" or "Connected Home" portfolio. The control and/or monitoring interfaces for these products can be accessed through proprietary smartphone applications specific to that product line. Some older entertainment devices may not feature the appropriate network interfaces required for home network connectivity. In some situations, USB dongles and PCI Network Interface Cards are available as accessories that enable this functionality. The convenience, availability, and reliability of externally managed cloud computing resources continues to become an appealing choice for many home-dwellers without interest or experience in IT. For these individuals, the subscription fees and/or privacy risks associated with such services are often perceived as lower cost than having to configure and maintain similar facilities within a home network. In such situations, local services along with the devices maintaining them are replaced by those in an external data center and made accessible to the home-dweller's computing devices via a WAN connection. Small standalone embedded home network devices typically require remote configuration from a PC on the same network. For example, broadband modems are often configured through a web browser running on a PC in the same network. These devices usually use a minimal Linux distribution with a lightweight HTTP server running in the background to allow the user to conveniently modify system variables from a GUI rendered in their browser. These pages use HTML forms extensively and make attempts to offer styled, visually appealing views that are also descriptive and easy to use. Apple devices aim to make networking as hidden and automatic as possible, utilizing a zero-configuration networking protocol called Bonjour embedded within their otherwise proprietary line of software and hardware products. Microsoft offers simple access control features built into their Windows operating system. 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.
