=====Cable Types=====

|<85em>|
^ Cable Type  ^ Shielding                               ^ Description                                                          ^ Use Case                                                        ^
| UTP         | None                                    | Twisted wires to reduce EMI and crosstalk                            | Most common and basic type of cable                             |
| S/UTP       | Foil wrapping or copper braid jacket    | Twisted wires wrapped with shielding material                        | Reduces EMI and crosstalk more than UTP                         |
| STP         | Foil wrapping around each twisted pair  | Each pair of wires wrapped in foil for added protection              | Provides better shielding than UTP                              |
| S/STP       | Combines S and STP shielding            | Twisted wires wrapped in foil, then wrapped in a shielding material  | Provides highest level of protection against EMI and crosstalk  |

=====Ethernet Cable Categories=====
  - Cable / data speed recommendations do not mean that higher than specified data speeds are not achievable, but rather such speed are not recommended and probably not be reliably achieved.
  - Clearly higher specified cable / speeds can provide performance at lower speeds that may not otherwise be indicated. For example, 10Mbps and 100Mbps can be achieve on CAT5E and up.
