The solution is the Home LAN, to network the computers and share the resources. A LAN A Local Area network is made up of two or more computers and peripherals, like printers or scanners, which are connected together in one building. In our case the home network is a LAN in a home. The primary media used in implementing a LAN today are twisted pair, coaxial cable and wireless. The majority of home LANs use coaxial cable or twisted pair.
Coaxial cable is the cheapest physical medium for setting up a network.
The topology of a coax LAN is a linear bus topology. This means that the cable goes from one computer to another until it reaches the end of the networked computers, then loops back to the beginning. Because the cable goes thru all the machines, if the wire is damaged anywhere or there is a short in the wire the whole network goes down. Another major problem with coaxial cable is that the maximum transfer speed is 10 mega bits per second. On the other hand twisted pair, or rather unshielded twisted pair is capable of speeds from 10 mega bits per second to 100 mega bits per second to the ultra fast 1,000 mega bits per second, or the gigabit network.
