RJ is a telephone and data jack standard and application registered with the Federal Communications Commission (FCC). The names of devices such as RJ-11 and RJ-45 are widely misused in the telecommunications industry. A more precise way to identify a jack is to specify the number of positions (width of opening) and the number of conductors. Examples include eight-position, eight-conductor or six-position, four-conductor. Some jacks have protective capabilities such as integrated filters to protect against unwanted signals or some type of magnetics to provide filtering signal conditioning, and isolation.

Personal Computer Memory Card International Association (PCMCIA) is a non-profit trade association and standards body that promotes PC card technology, miniature cards and SmartMedia® cards by defining technical standards. In the past, PC cards were known as PCMCIA cards. Now, the industry refers to products based on this technology as PC cards, PC card hosts and PC Card Software. Only the association itself is referred to as the PCMCIA. SmartMedia is a registered trademark of Toshiba Corporation.

	Contact Size (AWG)		An electrical contact is the termination of an electrical wire in the connector's pin or socket. Contact size, also referred to as termination size, is the maximum diameter wire the connector can accommodate.    Wire size is measured according to the American Wire Gauge (AWG) standard. In North America, wire area is measured by the American Wire Gauge (AWG) to indicate conductor size. The AWG is used to measure certain conductors including copper. The higher the AWG number the thinner the wire. This is because AWG stems from a measurement that represented the number of times the copper wire was run through a wire machine that reduced the diameter of the wire. Thus 24-gauge wire went through the machine 6 more times than 18-gauge wire.
