Chapter 11—Networking<br />
• Wiring st<strong>and</strong>ard<br />
• Length<br />
• End with crossover (if any)<br />
• _______ (blank) for computer ID<br />
The cables should be labeled at both ends to make matching<br />
the cable with the correct computer easy <strong>and</strong> to facilitate troubleshooting<br />
at the hub. Check with your cable supplier for suitable<br />
labeling stock or tags you can attach to each cable.<br />

Network Cabling Distance<br />
Limitations<br />
Network distance limitations must be kept in mind when creating a<br />
network. If you find that some users will be “out of bounds”<br />
because of these limitations, you can use repeaters, routers, or<br />
switches to reach distant users.<br />
Table 11.10 lists the distance limitations of various kinds of LAN<br />
cable.<br />
In addition to the limitations shown in the table, keep in mind<br />
that you cannot connect more than 30 computers on a single<br />
Thinnet Ethernet segment, more than 100 computers on a<br />
Thicknet Ethernet segment, more than 72 computers on a UTP<br />
Token-Ring cable, <strong>and</strong> more than 260 computers on an STP Token-<br />
Ring cable.<br />
