They often use many more wires and can require a dedicated network administrator to ensure the health and productivity of the network.
However, networks can also connect computers that are not in the same geographic location. Such networks, known as enterprise level networks, are in use by larger companies or organizations, such as the military, that have multiple offices and locations. They may span the country or even the world. These networks don't rely upon Ethernet cables. Rather, they use the protocols like TCP/IP, also known as the Internet Protocol suite, for connection-less networking.
