Answer:
"Waterfall" is the correct answer for the above question.
Explanation:
- The Waterfall model is a model which is the first model recognized by some scientists is used to states some rules to develop the software. It is based on the phases of the SDLC. The SDLC is the collection of phase that is used in software development.
- The waterfall model moves like water moves. It means any next phase starts if the previous phase is completed and the user can not move into previous steps of the model.
- This is also asked by the question. Hence the answer is the waterfall model.

Explanation:
In web accessibility, how well one color stands out from another color determines whether or not most people will be able to read the information.
Contrast makes things look different and stand out
Answer:
2^32 times as many values can be represented
Explanation:
32-bit. This means that the number is represented by 32 separate one’s and zero’s. 32 bits of 2 possible states = 2^32=4,294,967,296 possible values.
Integer meaning that only whole multiples of one are accepted.
Signed meaning that negative values are accepted. This halves the number of possible positive values (roughly), so the largest number you can represent is 2^31–1=2,147,483,647, but instead of 0, the smallest number you can represent is -2,147,483,648. An unsigned 32-bit integer, by contrast, can represent anything from 0 to 4,294,967,295.
