Although the construction of a portable cord varies depending on the type, a standard cord has at least two stranded copper conductors sized between #18 and #2 American wire gauge (AWG). The copper stranding, insulation , and outer jacket directly influence the physical properties of the cord and its permitted uses.
IEEE 802.1D is the Ethernet MAC bridges standard which includes bridging, Spanning Tree Protocol and others. It is standardized by the IEEE 802.1 working group. It includes details specific to linking many of the other 802 projects including the widely deployed 802.3 (Ethernet), 802.11 (Wireless LAN) and 802.16 (WiMax) standards.

NEMA 1-15P (two-pole, no ground) and NEMA 5-15P (two-pole with ground pin) plugs are used on common domestic electrical equipment, and NEMA 5-15R is the standard 15-ampere electric receptacle (outlet) found in the United States, and under relevant national standards, in Canada (CSA C22.2 No. 42 [1]), Mexico (NMX-J-163-ANCE) and Japan (JIS C 8303).
1-Wire is a wired half-duplex serial bus designed by Dallas Semiconductor that provides low-speed (16.3 kbit/s [1]) data communication and supply voltage over a single conductor. [2] 1-Wire is similar in concept to I 2 C, but with lower data rates and longer range.
In building wiring, multiway switching is the interconnection of two or more electrical switches to control an electrical load from more than one location.A common application is in lighting, where it allows the control of lamps from multiple locations, for example in a hallway, stairwell, or large room.

The characteristic impedance of twin lead is a function of the wire diameter and its spacing; in 300 Ω twin-lead ribbon cable, the most common type, the wire is usually AWG 20 or 22 (0.52 or 0.33 mm²), about 7.5 millimetres (0.30 in) apart.
