"Now here is the fun part, and the part of this article that will
be most relevant to any Cat 5 cabling job. So far I've covered
information about making holes in plaster and tubing and bracketing
decisions. That information may or not have proved useful to your house
or office, depending on where you are running the cable - through a
roof, a wall, or on the exterior as I have done. But no matter where or
how you have run your Cat 5, each end of each cable needs to be properly
fitted with an RJ45 female connector."
