Twisted-Pair Cabling
There are different grades, or categories, of twisted-pair cabling. Category 5
is the most reliable and is highly recommended. Category 3 is a good second
choice. Straight-through cables are used for connecting computers to a hub.
Crossover cables are used for connecting a hub to another hub (there is an
exception: some hubs have a built-in uplink port that is crossed internally,
which allows you to link or connect hubs together with a straight-through
detailed information on
straight-through and
crossover cabling.
To determine which wire is wire number 1, hold the cable
so that the end of the plastic RJ-45 tip (the part that goes
into a wall jack first) is facing away from you. Face the clip
down so that the copper side faces up (the springy clip will
now be parallel to the floor).When looking down on the
copper side, wire 1 will be on the far left.

cable instead).
You can buy pre-made Category 5
cabling, or cut and crimp your own.
Category 5 cables can be purchased
or crimped as either straight-through
or crossover. Inside a Category 5
cable are 8 thin, color-coded wires
inside that run from one end of the
cable to the other. All 8 wires are
used. In a straight-through cable,
wires 1, 2, 3, and 6 at one end of the
cable are also wires 1, 2, 3, and 6 at
the other end. In a crossover cable,
the order of the wires change from
one end to the other: wire 1 becomes
3, and 2 becomes 6.
