Binary

Building Blocks of Hardware: From Logic Gates to Modern CPUs Hardware starts with simple parts that handle binary information. The basic unit is the logic gate, a tiny switch that passes or blocks a signal. Even a simple calculator relies on hundreds of these gates working together. By arranging gates in different ways, engineers build circuits that can sense, decide, and control real devices. This is the backbone of every computer, phone, and appliance you use. ...

Building a Solid Foundation: Core Computer Science Fundamentals for Beginners Computer science is not only about writing code. It helps you think clearly and solve real problems. At its core, CS studies how to break big tasks into simple steps, how to store and move information, and how to judge whether a plan will work. For beginners, building a small, solid foundation makes any future learning faster and more enjoyable. ...
