Logic-Gates

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. ...

The Building Blocks of Hardware: From Transistors to Systems Hardware starts with tiny switches called transistors. A transistor can turn a current on or off, creating a binary 1 or 0. This simple idea powers almost every electronic device, from a watch to a server. Over time, engineers packed billions of these switches into a single chip, enabling more capable and energy-efficient devices. From transistors to logic gates, the next step is to build circuits. Digital logic uses gates such as AND, OR, and NOT to perform simple tasks. Put several gates together, and you get more complex behavior: adding numbers, comparing values, or storing a bit of data. These small blocks form the logic that runs software and controls hardware. ...
