C is more than fifty years old. That immediately raises a reasonable question: Is learning C still useful for a programming career in 2026? If…
Modern programmers often learn C and Unix as two separate subjects. C is introduced as a programming language. Unix is introduced as an operating…
Python dominates modern programming education. AI can now generate code in seconds. Modern programming languages provide powerful libraries, automatic memory management, and high-level abstractions that…
C and C++ look very similar. They share much of the same syntax, and C++ was originally developed from C. But today, they are two…
A CPU contains many important components: registers, an ALU, control logic, memory interfaces, and other supporting circuits. But these components are useful only when they…
In the previous lessons, we learned how logic gates can perform simple operations. We then built a half adder, which can add two binary bits.…
In the previous lesson, we learned how a half adder can add two binary bits. A half adder takes two inputs: A B and…
Computers perform billions of arithmetic operations every second. But underneath CPUs, ALUs, registers, and complex instruction sets, arithmetic begins with a surprisingly simple question: How…
Computers perform billions of calculations every second. They add numbers, calculate memory addresses, update counters, compare values, and execute instructions. But deep inside the processor,…
Computers naturally store patterns of bits. For unsigned integers, this is straightforward. With 8 bits, for example: 00000000 = 0 00000001 = 1 00000010 =…
In Part 1, we learned how binary numbers work. We saw that binary uses only two digits: 0 and 1 We also learned about bits,…
Computers can process text, images, video, programs, websites, games, and artificial intelligence. But underneath all of this complexity is a surprisingly simple idea: binary. Binary…
A processor can perform millions or billions of operations every second. It can add numbers, compare values, calculate addresses, control loops, call functions, and move…
Apple Wants a Federal Judge to Stop OpenAI Before It’s Too Late The artificial intelligence industry may have just entered one of its most important…
What Is an LLM? How ChatGPT Actually Works ChatGPT can answer questions, write code, summarize documents, translate languages, analyze images, and help complete complex tasks.…
A modern GPU is far more than a chip with thousands of cores. Follow one frame from CPU commands through vertices, triangles, rasterization, shaders, VRAM,…
GPUs may contain thousands of cores, but those cores are not equivalent to CPU cores. This article explains latency, throughput, parallel computing, memory architecture, and…
Modern computing is largely built around two major processor architecture families. Traditional desktop computers, gaming PCs, workstations, and many servers primarily use x86 processors. Smartphones,…
Part 1: The Mystery of Forgetful RAM and Long-Term SSD Memory Have you ever noticed a strange contradiction inside your computer? Your RAM and your…
A computer motherboard may look confusing at first. Its surface is covered with chips, slots, connectors, pins, capacitors, inductors, resistors, heatsinks, and countless tiny electronic…
