Differentiate between functional and non-functional requirements?

Solution:

Functional requirements specify the intended behavior of a system or product and describe what the system should do. They are related to the features and functions that a system must have to meet its users' needs. Examples of functional requirements include user authentication, data validation, reporting, and data search capabilities.

Non-functional requirements specify how well the system or product must perform certain functions or characteristics. They are related to the system's performance, usability, reliability, security, and other non-functional aspects. Examples of non-functional requirements include response time, scalability, availability, accessibility, and maintainability.

In summary, functional requirements specify what the system must do, while non-functional requirements specify how well the system must do it. Both types of requirements are critical to the success of a project and must be clearly defined and documented during the requirements gathering and analysis phase.
