This is a guide for installation of proper lan cabling. It can be scaled from a small home lan to an office with a large number of users.
The easiest way to install lan cabling is to run cables direct from the switch to each computer. This is the cheapest method but does not allow flexibility. For instance if the user wants to relocate a computer in a different part of the room you may have to run a whole new cable because the one you installed is now not long enough.
