The content of this post is a summary of what I’ve learned so far from the lab. The block of code below was provided as a starting point for this lab. Running this block of code will fill the top right screen with Yellow. In order to understand what is going on here, there’re a few things that we need to know first. The screen’s color is originally black and it is divided into four smaller rectangle blocks (which can also be called pages) defined by pixels. Each rectangle block has exactly 256 pixels.
