The ICS (Internet Connection Sharing) wizard warns you if you have any disconnected Internet connections. You can also choose to ignore the disconnected connections by clicking the Ignore Disconnected Hardware checkbox. Another aspect of ICS is that it lets you share an Internet connection without needing a router to perform the various networking functions that connect your computers and printers to the network. If all your computers have NICs (network interface cards), you can connect them to each other using ICS. Its a way to enable networking without incurring the headaches that may come with setting up a network using a router. ICS uses a service called DHCP (Dynamic Host Control Protocol) Allocator that performs the functions of a DHCP server that is usually part of most routers: it assigns IP (Internet Protocol) addresses to computers on the network and designates the network gateway (in this case, the host computer running ICS). ICS also features a DNS (Domain Name Server) Proxy (for translating network IP addresses into network names), (Network Address Translation, for converting private network IP addresses into public addresses), and an auto-dialer for automatically dialing connections. Essentially, ICS converts the host computer into a networking gateway by retrofitting it with the services needed to perform that function. To set up a network using ICS, you must first install ICS on the computer in your network that is directly connected to the Internet via your cable or DSL modem; this computer will serve as the host/gateway. For ICS to work, this gateway computer must be running Win98SE or later. This restriction doesnt apply to the

Network gateways interconnect networks with different, incompatible communication protocols. They perform a Layer-7 protocol-conversion to translate one set of protocols into another (for example, from TCP/IP to SNA or from TCP/IP to X.25).
Network processors handle a wide array of tasks needed to support network systems, including routing, compression, encryption, authentication, and protocol conversion.
Network routers are protocol-dependent devices that connect subnetworks, or that break down a large network into smaller subnetworks.
Network switches connect network devices to host computers and allow a large number of devices to share a limited number of ports. They increase network capacity and speed by examining and filtering data packets. Switches also regenerate forwarded packets, reducing collision rates and permitting the use of additional nodes.
