pin - Computer Definition
A type of diode used as a light detector in optical transmission systems. A PIN comprises three layers of semiconducting material in the forward current-carrying direction. The first layer is chemically doped, i.e., infused with impurities, to create a positive (p) electromagnetic region.The second layer is either undoped or lightly doped to retain its intrinsic (i) properties and, therefore, is neither strongly positive nor strongly negative. The third layer is doped to create a negative (n) electromagnetic region. So, the diode structure is Positive, Intrinsic, and Negative, or PIN. A PIN generates a single electron from each photon received and, therefore, does not provide a significant gain, or increase in signal strength. However, PINs are fairly rugged and inexpensive. PINs generally are matched with light-emitting diode (LED) and vertical cavity surface-emitting laser (VCSEL) light sources and multimode (MMF) glass optical fiber (GOF) or plastic optical fiber (POF) in relatively low speed, short haul fiber optic transmission systems (FOTS). See also diode, dopant, FOTS, GOF, laser diode, LED, light detector, MMF, POF, and VCSEL.
(1) The male lead on a chip or cable connector. Each pin is plugged into its female counterpart to complete the circuit. The number of pins reflects the number of wires, or pathways, that carry signals. See plugs and sockets.
(2) (PIN) (Personal Identification Number) A type of password used for authentication. Typically four to six digits, the PIN is used to authenticate ATM and debit cards. The PIN may be the only authentication mechanism required, or it may be used with another password.
(3) To place an object onto a home screen or home page. For example, in Windows 8 and Windows Phone, "Pin to Start" means to place an application icon onto the Start screen. See Pinterest.
(4) (PIN) (Processor Independent NetWare) A version of NetWare 4.1 designed for portability to multiple platforms. Development was stopped in early 1995.
