ICS allows multiple computers to be connected to the Internet, in which they use the same Internet connection and IP address.
The full form of ICS is “Internet Connection Sharing.”
For example, many computers in a house are connected with the same cable or DSL modem for a router. As long as the router is connected with the modem, each computer connected with the router is connected with the Internet.
Network address translation (NAT) allows computers to share the same IP address.
ICS can also be done using some Softwares. Windows 98 and later, as well as Mac OS X, support Internet connection sharing.
This allows modifying the network settings of a system so that the computer is transformed into a gateway. Other computers can also use the computer’s Internet connection in the same network.
Windows users can use similar programs such as WinGate and WinProxy to achieve the same result.
Where Internet connection can be shared with the help of software, but using hardware (such as a router) is considered a much easier and hassle-free solution.
