Chapter 12. Home Networking Protocols > Peer-to-Peer Networking

12.2. Peer-to-Peer Networking

Another popular home network application is for sharing files on hard disk drives, printers, scanners, cameras, and the like among multiple PCs. Figure 12.7 shows how multiple PCs in a household can be interconnected via a Category 5 twisted pair–based 10BaseT/100BaseTX Ethernet. To locate the Ethernet hub at a central location, a star or home-run telephone wiring topology with data-grade cables is required. Because only two pairs are used by the Ethernet, conventional telephone sets can still be connected to the telephone service using one remaining pair of the same Category 5 twisted pair cable. On each wall plate, one RJ-45 jack connected to Orange/Orange stripe and Green/Green stripe pairs is used for data networking, and another RJ-11 jack connected to the Blue/Blue stripe pair is used for telephone service. Home-run Category 5 wiring becomes more popular for newly constructed homes. Without home-run data-grade cable wiring, a home network can still be implemented using HomePNA based on existing regular telephone wiring, HomePlug based on in-house electrical wiring, or wireless technologies such as HomeRF and IEEE 802.11.
