Sharing is the use of a device with Internet access
such as 3G cellular service, broadband via Ethernet, or other Internet gateway
as an access point for other devices. It was implemented by Microsoft as a
feature of its Windows
operating system (as of Windows 98 Second Edition and later) for
sharing a single Internet access on one computer between other computers on the same local area network. It
makes use of DHCP and network
address translation (NAT).
