Udon is a programming language for adding interactivity to VRChat worlds. UdonSharp is a tool for creating Udon scripts by writing in C#, which is the programming language most Unity games are made in. This guide aims to teach the basics of programming so that someone who has never programmed before can create their own Udon scripts with UdonSharp.

Silicon is a semi-conductor -- a material that isn't a conductor and isn't an insulator, but somewhere on the fence. We can nudge the conductivity of silicon one way or another by mixing it with other materials (known as doping[1]) or by placing it in the electric field of a nearby charged piece of metal (known as the field effect[2]).
A transistor is a tiny microscopic device made from semi-conductors that utilize doping and the field effect to turn circuits on and off within your CPU. For example, you can dope the silicon within a transistor to make it not conductive so that it blocks the flow of electricity through a circuit. Then when you want to use that circuit, you would use the field effect to make the silicon conductive again. Here is a diagram showing how that'd work:
