The basic difference is the pin of the transistor that is grounded. The common collector has the collector pin grounded, common emitter has the emitter pin grounded and common base, as you guessed it, has the base pin grounded. The following article explains the differencnes perfectly.
What is a soundbar? VCC is more commonly labelled V+, VS+ or VDD (voltage drain drain). The common collector is responsible for the power coming from the base and the collector, while output is from the emitter-collector circuit. Integrated circuits with bipolar transistors have positive and negative power supplies.
