Answer:
While statements determine whether a statement is true or false. If what’s stated is true, then the program runs the statement and returns to the first step. If what’s stated is false, the program exits the while and goes to the next statement. An added step to while statements is turning them into continuous loops. If you don’t change the value so that the condition is never false, the while statement becomes an infinite loop.
If statements are the simplest form of conditional statements, statements that allow us to check conditions and change behavior/output accordingly. The part of the statement following the if is called the condition. If the condition is true, the instruction in the statement runs. If the condition is not true, it does not. The if statements are also compound statements. They have a header (if x) followed by an indented statement (an instruction to be followed is x is true). There is no limit to the number of these indented statements, but there must be at least one.

The four standard layers of a layered architecture are:
- presentation,
- business,

- database.
<h3>What is a Layered Architecture?</h3>
This refers to the architectural style that is used to show components with similar functions in horizontal layers that have specific roles.
Hence, we can see that no generic info system architecture was attached to the answer, so it would be impossible to create a layered architecture, so a general overview was given about layered architecture.
