| Term | Definition | 
|---|---|
| Z | Letter symbol used to represent impedance in ohms. | 
| Z0 | The characteristic impedance of a device or system. | 
| Zener Diode | A diode that maintains a relatively constant voltage when the reverse voltage across it is increased passed a specific point, called the zener voltage. | 
| zero voltage switch | A circuit designed to switch “on” at the moment the ac supply voltage crosses zero. This technique minimizes the radio frequency interference generated at switch closure. | 
| zero-suppression | The elimination of nonsignificant zeros in a numeral. | 
| ZIF | Zero Insertion Force – A component designed to eliminate the insertion and withdrawal forces during engaging and separating. | 
| Zone cabling | An architectural concept which splits the horizontal cabling into two sections. Eliminates the need to replace the entire horizontal cable in moves, adds and changes. | 
| z-Parameter | The set of parameters for a two port device that relates the input and output voltages to the input and output currents. |
