Electronics connectors are designed to transport both information and power. A {{w|pinout}} diagram describes the function of each pin such as to communicate data, transport power, physical function (keying), etc. In this comic there is an absurd alternative to the actual pins used in connectors. The pin labels are references to many tech issues and attributes, and not all may be documented correctly here. | Electronics connectors are designed to transport both information and power.

− | | Decorative elements are pieces of an assembly that serve only an aesthetic purpose without any technical function. This would not be particularly useful inside a connector, as almost no one will ever see it--however, in HDMI, pin 14 was reserved for future use in versions 1.0–1.3a (and was only assigned an official use in 1.4).

These units are used in particle physics, but the appearance is very similar to the common 3.3V supply. It would be a unit of electric potential equivalent to approximately 1.60217662 * 10<sup>-19</sup> volts. Thus 3.3eV/C would be 5.287183 * 10<sup>-19</sup> volts, or slightly more than 1/2 attovolts. It could also be read as +3.3 eV/c (per {{w|speed of light}}), in which case it is equivalent to a momentum of 5.3E-28 kg m/s, In high-energy physics, the momentum of particles is sometimes expressed in MeV/c or GeV/c units. |

− | A {{w|RF connector|coaxial RF connector}} has two contacts - one pin, and the shield; typically the whole connector is labeled with whatever function/signal is carried by the pair. The joke here is that the label is ''technically'' correct (the best kind of correct), but not very useful to the end user, as it does not specify the voltage rating, impedance, connector size, or other useful information about the cable. Some serial data transmission systems, such as {{w|Ethernet|Ethernet}}, used coaxial cable early on as a low cost, widely available solution, however most of these have largely become obsolete. A common coaxial cable still widely in use is {{w|RG-6|RG-6}}, which is typically used to deliver satellite television, cable television, and cable Internet services in the United States | + | A {{w|RF connector|coaxial RF connector}} has two contacts - one pin, and the shield; typically the whole connector is labeled with whatever function/signal is carried by the pair.
