In this first tutorial of the new year, we explore how a computer remembers binary data. Typically, computer Random Access Memory (RAM) is hidden inside little black chips. We have therefore constructed a RAM module that shows every single bit of data that it holds. It has the insane number of 101 LEDs. In the first part of the video, we explore how it works. In the second part, we connect it to a B4 Computer processor and observe the data-flow during arithmetic operations.
