So one and zero is the normal way that computers speak. And often we don't talk about just a one or a zero, but we talk about a width of them. Sometimes we talk about 32 bit CPUs or 64 bit CPUs or sometimes we talk about eight bit external databases or 16 bit registers. Or if you get into graphics cards, we have 256 bit memory. The important thing that all of these different chunks of ones and zeros have is that they all have a least common denominator of four. All of the numbers I just told you are divisible by four; 8,16, 32,64, 128 And if we know that, we can actually do something kind of cool, let me show you something over here on my computer. So I'm going to run a command called ipconfig, which we go over in great detail in other episodes. And I want you to take a look at this…
