MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Nonfunctional Requirements (NFRs) define system attributes such as security, reliability, performance, maintainability, scalability, and usability. They serve as constraints or restrictions on the design of the system across the different backlogs.

Detailed explanation-2: -Non-functional requirements define system properties and constraints e.g. reliability, response time and storage requirements.

Detailed explanation-3: -Examples of Non-functional Requirements Scalability: The system must be able to scale up or down as needed. Availability: The system must be available when needed. Maintenance: The system must be easy to maintain and update. Portability: The system must be able to run on different platforms with minimal changes.

Detailed explanation-4: -Some of the most typical non-functional requirements include performance, capacity, scalability, availability, reliability, maintainability, recoverability, serviceability, security, data integrity, manageability, and usability.

Detailed explanation-5: -What is the difference between functional and non functional requirements? Functional requirements explain how the system must work, while non functional requirements explain how the system should perform.
