This article explains how CPUs interpret binary signals as voltage levels, describes basic logic gates such as AND, OR, NOT, shows how they combine to perform arithmetic like addition, and clarifies that hardware itself lacks understanding, relying on human-designed instruction sets and compilers to give meaning to 0s and 1s.
This article explains how basic electrical phenomena, relays, and binary arithmetic combine to form logic gates, adders, flip‑flops, counters, RAM, and ultimately a rudimentary 8‑bit computer, illustrating each step with clear diagrams and practical examples.
A classroom tale follows elementary students as they discover binary counting with their fingers, translate it into truth tables, explore AND, OR, and NOT gates, and progressively build one‑bit and multi‑bit adders, illustrating fundamental digital logic concepts.
This article explains how basic semiconductor concepts and diode‑based logic gates can be combined into simple arithmetic circuits, registers, and a minimal instruction set to construct a functional 4‑bit CPU, illustrating each step with diagrams and historical context.
