What are the titles for the most left bit and the most right bit?
• Most Left → Most Significant Bit • Most Right → Least Significant Bit
What is Signed Binary?
Signed Binary are binary values of positive and negative, containing 2 variables of Sign and Magnitude. Signed binary has a Sign Bit, which is the MSB, at 1 it is negative, and at 0 it is positive. It cannot be used to processing zeroes, because zero cannot be positive or negative.
