Addition:
VCC, VEE, VBB are grounded voltages of a collector, emitter, and base, respectively, on a transistor.
The reason this letter is doubled is to represent a voltage connected between ground and the collector(/emitter/base). Since there is no notation to identify ground (0), the corresponding letter is doubled (IEEE standard). One way to read this notation is as the 'grounded voltage of the collector/emitter/base."
Answer
The representations like Vcc ,Vbb , Vee etc are just a part a nomenclature.
it is used to represent the voltage given to the nodes of the transistor
in this nomenclature voltage given to the ends are denoted by the letter v for the supply voltage and 2 times the first letter of emitter collector or the base where the voltage is given
A: ABSOLUTELY Vcc must always be positive to ground reference. That does not means that it will not work if Vcc is at ground and ground is -5 volts. both situation are valid.
When the magnitude of Vcc and Vee of op-amp are different the op-amp produces waveforms equal in the size of each rail.
IEEE stands for Institute of Electrical and Electronics Engineers. It is an organization made up of engineers, scientists and students who develop standards for the computer and electronics industry.
just conect gnd to the vcc
these two pins are biasing pins of ICs.
In electronics it stands for "common collector voltage" (Vcc) Online it stands for " virtual credit card" .There are many sites selling virtual cards for online purchase.
I believe that Vcc stands for Voltage Common Collector. This is because the voltage is hooked up to the collector of the transistor.
VCC is an electronics designation that refers to voltage from a power supply connected to the "collector" terminal of a bipolar transistor. In an NPN bipolar junction transistor, it would be +VCC, while in a PNP transistor, it would be VCC More about sim card .... https:// telecom-hyb.blogspot. com/2017/09/what-is-sim-card.html
if you are reffering to Vcc than it means- It is the positive power supply used for TTL gates it is nothing but simple dc power supply. if we use CMOS than we use Vdd for indicating power supply these are method for indicating power supply.

INT in the Intel stands for "INTegrated"Intel stands for INTegrated ELectronics
In electronic circuits, Vss is ground or 0v and Vdd is the the positive supply. The s and d come from the source and drain connections on MOS transistor devices. In a similar way Vcc is also the positive supply, the c coming from the collector on bipolar transistors. The terms Vcc and Vdd are normally interchangeable.
