	*[[wikipedia:NIC\|NIC]] - Network Interface card - This is both an electrical interface to the router/modem , and a logical board that communicates to the rest of the pc , usually registered jack forty five or registered jack eleven standard the cable to provide a carrier for the signals either shielded or ~~unsheilded~~. When you connect to the Internet for example the nic should send out fast link pulses that try to establish the acceptable speed of connection between the computer and the modem/router on the global side. These pulses are of a fixed length - if one side can respond within x number of ~~miliseconds~~ it will communicate at y speed, assuming both sides are set to ~~autonegociate~~. NIC has a Media access control or a Burned in address inside one of its microchips - this will NEVER change (though it can be falsified) unless you get a new nic.		*[[wikipedia:NIC\|NIC]] - Network Interface card - This is both an electrical interface to the router/modem , and a logical board that communicates to the rest of the pc , usually registered jack forty five or registered jack eleven standard the cable to provide a carrier for the signals either shielded or unshielded.
