FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Nonfunctional requirements are mostly quality-related requirements which include the areas of performance, availability, reliability, usability, flexibility, configurability, integration, maintainability, portability, and testability.

Detailed explanation-2: -Non-functional Requirements Example: Emails should be sent with a latency of no greater than 12 hours. Each request should be processed within 10 seconds. The site should load in 3 seconds when the number of simultaneous users are > 10000.

Detailed explanation-3: -Non-functional requirements or NFRs are a set of specifications that describe the system’s operation capabilities and constraints and attempt to improve its functionality. These are basically the requirements that outline how well it will operate including things like speed, security, reliability, data integrity, etc.

Detailed explanation-4: -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-5: -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.
