In this class, our instructor introduced another popular base system, hexadecimal, or base 16. Hexadecimal is similar to decimal, only that the first six letters of the alphabet represent numbers 10-15.

We then did some practice problems converting binary to hexadecimal, which is simple if you think in groups of four. The picture from my notes should explain this further. We wrapped up hexadecimal by learning about color systems, how they use hexadecimal to represent the amount of each color.

Finally, our instructor introduced binary addition. It seems similar to decimal addition, you go down the line and "carry over" anything that can't fit within the present digit. The only caveat is overflow, a term our instructor hinted would be on our exam.

Overflow occurs when the sum of binary numbers exceeds the range of the two numbers being added. The reason this is an issue has to do with memory having an assigned amount of space. Some of the ways to prevent overflow are using a larger bandwidth or having software that detects it.
