The two types of Requirement are? Successful and Non-Successful Station and Non-Stationed Fixed and Non-Fixed Functional and Non-Functional

The question you posed outlines two primary classifications of requirements used in systems development and software engineering: functional and non-functional requirements.

1. Functional Requirements: These specify what a system should do. They define the specific behaviors or functions of a system, including processes, data handling, and interaction with users or other systems. For example, an online shopping website needs functional requirements to allow users to browse products, add items to a cart, and complete a purchase.

2. Non-Functional Requirements: These define the quality attributes of the system. They specify criteria that can be used to judge the operation of a system rather than specific behaviors. Non-functional requirements include usability, reliability, performance, security, and scalability. For example, a non-functional requirement might state that a website must load in less than two seconds under normal load conditions.

Understanding the distinction between functional and non-functional requirements is vital for ensuring a system meets both the explicit needs (functional) and the quality expectations (non-functional) of its users.
