… those who understand binary, and those who don’t! Today I thought I would share a video link with everyone that explains how binary works. If you don’t know, binary is how computers know what to do. At some level, everything the computer does is because of the binary base-2 number system. One and zero, on and off, true and false. This is because electricity is either flowing or it isn’t, so base-2 math of binary is logical and an essential part of computer science. Check out this fun video by Sal Khan of Khan Academy as he explains how binary mathematics works:
