LM7805 is not a microcontroller. LM7805 is an +5.0V 1A voltage regulator.
The term LM7805 refers to a type of semiconductor. The number tells what kind it is and what the voltage output is. More information about this can be found online.
The case of the TO-220 LM7805 regulator is device ground. If the heatsink is also ground, you do not need an insulator. If the heatsink is not ground, or if you need to maintain distinct grounds, or if the LM7805 ground is something else besides ground, you need an insulator. Its up to you, since you are responsible for system and circuit design.
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.

positive 5 volts
It stands for a manufacturer's code (NATIONAL INSTRUMENTS)
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
Hello there, I know a great place where you can find paypal vcc at a cheap rate. I bought several vcc from them. They delivered Instant, and working really fine. So I think that website can be helpful for you. Here is name of the website BESTVCCSERVICE. COM

Yes
You would not want to connect Vcc and Gnd together. That would short circuit the power supply.
