MessageGood morning.

Good morning. After this series, I understood why I had trouble programming in ASM. 11/12 — How I Learned to Calculate — My Story — The Calculating Machine (6 Parts). —————— Have you ever stopped to think about how a computer actually works? Not in theory. But step by step — instruction by instruction. Where does information come from? Where does it go? How does the computer know what to do next? How does it calculate? How does it remember? *The Complete Series (6 Parts)* 1. Registers — How to store values while the computer works 2. The Control Unit — How to coordinate operations 3. The ALU — How to calculate 4. Numbers — How the computer understands zeros and ones 5. The Byte — How a standard was born 6. Memory — Where information is kept *Why Does This Matter?* You use computers every day. Your phone, your laptop, the server hosting your social networks — everything is built on these same pillars. Understanding how they work together is understanding the most important machine in modern history. To open each section directly, use the timestamp links below: Part 1: Registers (Flip-Flops and Fast Storage) (Covers the concept of feedback from 1918, flip-flops to store a single bit, and the creation of registers to hold temporary values during calculations) https://www.youtube.com/watch?v=5BI7I1yxQZ0&t=0s Part 2: The ALU (Arithmetic Logic Unit) (Covers the component responsible for logical and mathematical operations, from the half-adder to the architecture outlined by John von Neumann in 1945) https://www.youtube.com/watch?v=5BI7I1yxQZ0&t=4m19s Part 3: The Control Unit (The Conductor of the Cycle) (Covers the orchestrating component of the machine that drives the continuous cycle of fetching, decoding, and executing each instruction) https://www.youtube.com/watch?v=5BI7I1yxQZ0&t=9m21s Part 4: The Binary System (The Language of the Machine) (Covers how two-state electrical circuits — on and off — represent and operate numbers using powers of two in the binary system) https://www.youtube.com/watch?v=5BI7I1yxQZ0&t=14m07s Part 5: The Byte (The IBM System/360 Standardization) (Covers the need to group bits to represent characters, the coining of the term by Werner Buchholz in 1956, and the 8-bit industry standard established by IBM in 1964) https://www.youtube.com/watch?v=5BI7I1yxQZ0&t=18m28s Part 6: Memory (Magnetic Cores and Addressing) (Covers the evolution of large-scale storage: from Williams Tubes and Mercury Delay Lines to the reliable, non-volatile magnetic-core memory of 1953) https://www.youtube.com/watch?v=5BI7I1yxQZ0&t=23m24s —————— https://youtu.be/5BI7I1yxQZ0
