This week  we talked about binary and hexadecimal. We also looked at how to convert from one to the other. This is the third time I’ve come across this topic in college so far so I’m pretty familiar with it. Binary is all 1′s and 0′s and is counted using the power of 2′s. It goes from 0 t0 255. However, hexadecimal is counted using the power of 16. It uses numbers and letters. The numbers are 1 through 9 and letters A through F are used to represent the other numbers 10 through 16.
