VCC stands for Voltage Common Collector, which is a type of transistor circuit configuration commonly used in electronic circuits. In this configuration, the collector terminal of the transistor is connected to the positive power supply voltage (VCC), and the emitter terminal is connected to ground or a lower voltage level. The base terminal of the transistor is used to control the flow of current between the collector and emitter terminals. VCC can also refer to Virtual Credit Card, which is a temporary credit card number used for online purchases to protect against fraud.
