Video Description:
Inside your smartphone, there are billions of transistors, but have you ever wondered how they actually work and how they can be combined to perform tasks like multiplying two numbers together? One rather interesting thing is that transistors are a lot like Lego Bricks assembled together to build a massive Lego set, which we’ll explore further. In this video, we dive into the nanoscopic world of transistors. First, we'll see how an individual transistor works, then we’ll see how they are connected together and organized into logic gates such as an inverter or an AND gate. Finally, we’ll see how logic gates are connected together into large Macrocells capable of performing arithmetic.
