Describe different base numbering systems the computer uses

Different types of storage of numbers are important in today’s computers. After studying the articles and the videos in the Learning Activities section, describe three different base numbering systems the computer uses and when it would be advantageous(such as base 2, base 3, etc.) to use them. Then describe three different ways the computer stores numeric values internally.(such as one’s complement, signed/unsigned, etc.) Tell which system of storage would be best to use for the number -2021.
