At 13:30 the "double terminology" exists because you're mixing up two types of transistors. The picture you've drawn with the N and P-type doping is for a MOSFET (its terminals are gate, drain and source). But later you've drawn the schematic of a BJT (its terminals are base, collector and emitter). The main difference between the two types is that in a MOSFET the gate is insulated, so no current flows into or out of the gate (well, except when switching the transistor; it acts like a tiny capacitor). Whereas in a BJT, there must be a current flowing through the base to keep the transistor active.

Your video on GCC was how discovered your channel. Great channel
Awesome, thank you!
Great handwriting, great explanation, and great videos 👍
BTW, I'd love it if you made a video discussing JavaScript's shortcomings.
Take a class on linear algebra boys it is worth it.
