Analog to Digital Converters

The analog-to-digital converter (ADC) allows circuits controlled by microprocessors, Arduinos, Raspberry Pi, and various reasonable digital circuits to be connected to the real world. In the real world, analog signals have a continuous stream of information from a variety of sources and sensors capable of measuring sound, light, temperature, or movement, in addition to the many digital systems that interact with their environment by measuring analog signals from those transducers.

what is safe ? ac or dc motor ?
Can you give me all the different types of DC motor its quite confusing coz some info says it has only 4 which is series , shunt , compount , and permanent magnet which is only under the category of brushed DC motors it doesnt include yet the brushless and the sub category however when you recognize or notice that in flowchart there are several like the one self excited etc I wonder if its an updated version though but I need you to list all of them and explain each and what category or subcategory I mean the overall DC motors even in chatgpt there are some added like universal , stepper , servo , coreless and so on. Explain each one. Pls help me if you could summarize or elaborate all at once so that it would be easy to identify or determine the overall information and additionally per category should have definition as well as the following
