166 Chapter 8: TCP/IP Applications Getting Down to Business The way network communication all those ls and Os) goes in and out of a machine physically is through the NIC (network interface card). The way network communication goes in and out of a machine logically though, is through a program or service. A service is a program that runs in the background, independent of a logon, that provides functionalities to a system. Windows client machines, for instance, have a Workstation...
