The ease with which computers can be replaced or upgraded leaves older machines for the kids or wife to use. This means extra printers, phone lines, and other costs to make those individual machines ready for use. Suddenly, capability is duplicated and the cost has escalated, making a home LAN not so foreign. And, the confusion of who can use the connected computer is virtually eliminated, with everyone much happier when several computers share the Internet connection. Hubs are the central hardware connections that distribute the data to the correct address within the network.
Wiring is the medium that conducts the data from one location to another.
Today s technology has provided other network methods, which vary the above components for connectivity. The computers continue to require the NIC as the translator of the data between the computer and the remote connection. The hub and the wiring become less traditional through the house wiring, telephone or electrical wiring, and, thus, less efficient as data transmitters. These non-traditional methods of data movement have advantages and disadvantages, especially the wireless method. Another advantage of these techniques is when the computers to be connected are in separate rooms.
