Jargon buster
Plain-language definitions for the technical terms used above.
- Impedance
- Impedance is the total opposition a component or circuit presents to alternating current, measured in ohms, combining resistance with frequency-dependent reactance. It appears in many contexts, such as matching a speaker's impedance (for example 4 ohm or 8 ohm) to an amplifier or the input and output impedance of signal circuits, and a correct match helps avoid weak signals, distortion or damage.
- single-board computer
- A complete computer built onto one circuit board, usually including the processor, memory, ports, and connectors. This matters because accessories like heatsinks must match the board’s layout and mounting holes to fit properly.
