This article walks you through the basic principles of how computers operate, illustrating how simple logic gates can be combined to create binary arithmetic, memory storage, and control logic, ultimately forming a CPU that can execute instructions and perform calculations automatically.
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.
The article explains that a CPU merely reacts to voltage signals without any comprehension, illustrating how binary 0/1, logic gates, and combinational circuits form the basis of computation, and why compilers—not the CPU—interpret programming languages before execution.
In a sleepy second‑grade math class, a boy discovers binary counting with his fingers, leading his classmates to design logic‑gate circuits and ultimately build a 32‑bit adder, illustrating the fundamentals of digital computation and binary arithmetic.
This article explains how a single transistor acts as a switch, how combining AND, OR, and NOT gates yields logical completeness, how binary addition is built from these gates, and how registers, memory, instruction sets, and clock signals together form a functional CPU.
This tutorial explains how to recreate basic digital logic gates in Minecraft with redstone, encode decimal numbers using BCD, and combine those gates to construct a functional 4‑digit 7‑segment display, complete with an encoder, decoder, and blanking control.
This article explains the fundamental hardware components of a CPU, starting with early relay‑based machines, describing basic logic gates, constructing simple adders and an ALU, detailing memory and registers, and illustrating the fetch‑decode‑execute cycle and the evolution of machine code to assembly language.
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 whimsical classroom story shows how elementary students discover binary counting with fingers, learn about AND, OR, and NOT gates, design a one‑bit full adder, and ultimately connect dozens of them to create a 32‑bit binary adder that solves large addition problems.
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.
A whimsical classroom tale shows how elementary students discover binary representation with their fingers, translate it into truth tables, construct a one‑bit adder using AND, OR, and NOT gates, and then scale the design into a full 32‑bit binary adder, 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.
