What is the largest positive number one can represent in an eight-bit 2’s complement code? write your result in binary and decimal.

The largest positive number one can represent in an eight-bit 2’s complement code is 01111111.

Explanation:

It is displayed as 01111111₂ in Binary.

To derive its decimal equivalent, we have to convert the binary code into decimal as follows:

01111111₂ = 0 × 2⁷+ 1 × 2 ⁶+ 1 × 2⁵ + 1 × 2⁴ + 1 × 2³ + 1 × 2² + 1 × 2¹ + 1 × 2⁰

             = 0 + 64 + 32 + 16 + 8 + 4 + 2 + 1

            = 127

Therefore, the decimal equivalent is 127.

the major difference between the two is the objective and the reward of the game. candy crush has a puzzle theme with the objective of meeting a specific quota of points or objects, you are able to gain access to the next level and compete with peers on the process. on duolingo the objective is rather different, you are given sets of questions for you to answer for you to move to the next level and as for the reward, you are able to learn available language as this is an app developed to teach the user about other languages.
