Using the transistor base in here: transistor. I’m gonna talk about logic gates and some basic possibilities like adders, subtractors, multipliers, and divisors. The main idea in these basic posts is to trace the way to assembly instructions and so on. These logic gates are the lowest level we can reach in the hardware processing, obviously, these instructions alone don’t create anything really meaningful but the correct combination can create computer and processing machines of any type (except quantum computers but we’re not gonna talk about them today)...

Can be a amplifier or a switch, but today let’s put notes about switches because i founded more interesting: Silicon is a semiconductor 4 valence electrons Tetrahidro Cristal Doping semiconductor n-type doping: injecting small amount of an element like Phosphorous, that is similar to silicon and have 5 valence electrons, and having one more than silicon make the conductivity better The negative electrons that moves p-type element with 3 valence electron like Boron that way it create a hole that also increase the conductivity because the electrons can move into the hole itself The hole that is a lack of electron make it actually acts like a positive charge and that’s why the “P” type, and the movement here is the holes itself By the way that doesn’t mean they are actually positive and negative but neutral because the electron number of electron and protons inside Transistor are made of P-Type and N-Type doping Electron contacts in the ends/edges, there is the electrical contact in the middle isolated by an oxide layer(the gate)...
