What is the Single Responsibility Principle (SRP), and how do you use this in your designs?

You may have already recognized this is a technical question inquiring about a concept used by web architects. This indicates that you should keep your answer brief and to the point, anticipating a follow-up question from the interviewer. Also, make sure your answer corresponds to the operations and technologies used by the organization. This will help the interviewer begin to picture you in the role.

"The concept of single responsibility refers to a class doing one specific thing, known as its responsibility, and not attempting to do anything more than it is responsible for. This is known as high cohesion. Often, classes start out with high cohesion, but after several iterations with multiple developers updating them, they evolve into a low cohesion class. This can be corrected by refactoring the class."
