A reference designator unambiguously identifies the location of a component within an electrical schematic or on a printed circuit board. The reference designator usually consists of one or two letters followed by a number, e.g. C3, D1, R4, U15. The number is sometimes followed by a letter, indicating that components are grouped or matched with ...

A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.
In the United States, response codes are used to describe a mode of response for an emergency unit responding to a call. They generally vary but often have three basic tiers: Code 3: Respond to the call using lights and sirens. Code 2: Respond to the call with emergency lights, but without sirens. Alternatively, sirens may be used if necessary ...
Coder/decoder. CofA. Certificate of airworthiness. COMM or COM. Communications transceiver, Communications receiver, or Communications radio transmitter. Now, normally: either VHF or UHF; HF communications avionics are usually abbreviated simply HF. CORSIA. Carbon Offsetting and Reduction Scheme for International Aviation. COTS.
A von Neumann architecture scheme. The von Neumann architecture —also known as the von Neumann model or Princeton architecture —is a computer architecture based on a 1945 description by John von Neumann, and by others, in the First Draft of a Report on the EDVAC. [ 1 ] The document describes a design architecture for an electronic digital ...
The National Electrical Code ( NEC ), or NFPA 70, is a regionally adoptable standard for the safe installation of electrical wiring and equipment in the United States. It is part of the National Fire Code series published by the National Fire Protection Association (NFPA), a private trade association. [ 1]
The models created by Code 3 Collectibles, were stock models which had been customized or converted from their original state. A few examples of Code 3 Collectibles models plain white cars or vans which have been painted or have had decals added with the livery of a police force such as stripes, force badge/crest, force code etc. Extras such as lightbars and possibly tools have been added as well.
