Computer Basics for Noobs

Image
Some Reddit users ask for the "Basics" of how a computer works Some responders will tell you a transistor is a "switch" that is either "on" or "off" Typically, "on" is represented by an in-circuit positive voltage like +3.3V or more Typically, "off" is represented by  an in-circuit ground  voltage like +0.3V or less That explanation is misleading. A basic transistor circuit (e.g. with a resistive load) works as a voltage inverting amplifier. Put in a voltage representing "0" and the circuit outputs a voltage representing "1" Put in a voltage representing "1" and the circuit outputs a voltage representing "0"

Learning about Learning is just one of many topics that one can study. How about creating a Mind Map topped by LaX = Learning about ___ and continued by child nodes including the following: LaP = Learning about PYTHON LaO = Learning about Other Software LaL = Learning about LEARNING LaN = Learning about Note-taking (PKM) The above is a second round draft of a Mind Map for tying together various learning tags (#LaX) directed to different topics including (1= #LaP) learning about Python , (2= #LaL) learning about Learning , (3= #LaT) learning about Politics , (4= #LaSw) learning about Software Other than Python, (5= #LaO) learning about Personal Knowledge Management (PKM, note-taking, Obsidian), and so forth. This will be copied into my Obsidian vault for further elucidation including adding subtopics. TO BE CONTINUED LaL: You Forget Half of What You Read.
