| STP vs. UTP|
|What are the pro's and con's of using a Shielded Cable, Cat 5 or 5e for Data Transmission and what is the proper installation method for this type of cable? Grounding requirements at either end?|

The pros for STP is better EMI protection. The con is that it is more expensive and will require more labor to install and terminate.
Most situations will not require the use of STP ScTP cable, UTP (category 5e & 6), when properly installed will perform as specified.
Category 5 is no longer part of the standard, thus use category 5e instead.
As far as grounding and termination, it all depends on the manufacturer of the devices and the cable. Typically if it is used for a horizontal run, the shield is terminated and grounded at the closet end.
