November 13, 2022 - 5:12 amThanks a lot for sharing the knowledge, about the necessity for Harvard architecture.

November 13, 2022 - 5:12 amI still don't get what's actually happening inside the CPU. How does it "know" to put a value in the point counter? How do the CPU and memory "talk" so that the memory knows, or is forced to send, an instruction from a specific address? Why does running two voltages (1s and 0s) through a CPU do anything? Seems like the CPU "knows" certain instructions, but where does the "knowing" come from?

November 13, 2022 - 5:12 amWell my wonderful peoples, I've been searching far and wide and I am yet to find an answer, how does the computer actually generate the clock pulse that determines the speed. Is it a tiny capacitor being charged and discharged as i suspect or am I completely wrong and is it something entirely different. The internet seems stumped by this and I can only seem to find videos like this telling me the software side of things. I would be much obliged to recive any information about this subject and would greatly apreciate some further reading links.
-yours sincerely, some random internet person

November 13, 2022 - 5:12 amI’m watching many of these years after publishing and extremely grateful for these explanations! You truly have a talent for teaching.

November 13, 2022 - 5:12 amI still have question. How does Assembly Language which is a software code communicates with Silicon Chip which is a hardware i.e. how is conversion done to chip of assembly language.

November 13, 2022 - 5:12 amInteresting but I don’t understand how in the past there was a race with CPU manufacturers to have the highest number of MHz and that basically said how fast the CPU is.
Why is that no longer a thing?

November 13, 2022 - 5:12 am@4:40 am i high or did he explain the same thing like 5 times in 5 different ways ? 🤔

Fetch instruction from memory
Decode instruction
Execute instruction

November 13, 2022 - 5:12 amshort as a byte, hmmmm i wonder.
for the record a byte is combination of 8, 1's or 0's.
so it may look something like this 01100011 = 99 not so short now eh?

November 13, 2022 - 5:12 amIf anyone wants to understand this stuff at a very fundamental level, I would highly recommend Ben Eater's series on building a breadboard computer.

November 13, 2022 - 5:12 amRespected Sir.
Your explanation is very amazing. I have a great interest in low level computer stuff. Keep making these kind of videos. 👍👍👍

November 13, 2022 - 5:12 amThank you Bilbo. You are my IT mithril.

November 13, 2022 - 5:12 amThat green barred line printer paper is a blast from the past! Is it manufactured seriously any more, or is that just for fun?
I used to load deafening band printers with that stuff, and it would frequently mash it all up, and the whole print job would have to be redone.

November 13, 2022 - 5:12 amSir, Thank you for doing this lesson. I m sitting for BCS HEQ exams this november and this channel is my source of knowledge. I always find it difficult to understand that bubble concept in the pipeline, but now I do. thanks again.

November 13, 2022 - 5:12 amplease any one explain how cpu is outputing it on the screen i cant find anywhere!

November 13, 2022 - 5:12 amYou forgot to mention the Prock Architecture… oh wait , I haven't released it yet, its better that anything out there!

November 13, 2022 - 5:12 amCan this pipeline ‘bubble’ dilemma be a solution quantum computing can solve with its ability to compute instructions simultaneously regardless of a cycle?

November 13, 2022 - 5:12 amThanks, Dr. Bagley, you are an excellent public speaker and explained the CPU cycle quite clearly.
