“You have probably heard of computer memory, and now we are going to see exactly what that is. Since the only thing inside of computers is bits, and the only thing that happens to bits is that they either turn on or turn off, then it follows that the only thing a computer can ‘remember’ is whether a bit was on or off.””

“Each pixel on the screen has a unique address consisting of two numbers, the first being the left-right or horizontal position, and the other being the up-down or vertical position. The address of the top left pixel is 0,0 and the bottom right pixel is 319,199””

“Everything you see a computer do is a long concatenation of these very simple operations, the ADDing, NOTting, Shifting, ANDing, ORing, XORing of bytes,  Storing, Loading, Jumping and I/O operations, via the execution of the instruction code from RAM.””
