Non Functional Requirements : Not perform action capture conditions that do not directly relate to the behaviour or functionality of the solution, but rather describe environmental conditions under which the solution must remain effective or qualities that the systems must have. They are also known as quality or supplementary requirements. They can include requirements related to
-capacity
-speed
-security
-availability and information
-architecture and
-presentation of user interface
Example of non functional requirement: After entering the login credentials by the user  to login into the system, how much speed the system take in order to login represents non functional requirement..
Example: Response taken for login i s3 sec.
Example: Performance rating with 5 star for fridge.

Non-functional requirements are the requirements that are related to the behavior of the system. Non-functional Requirements describe the qualities of the process or system.
It includes scalability, security, performance, flexibility, reusability, reliability, and maintenance.
The documents that are prepared for non-functional requirements are known as Supplementary Support Documents (SSD).
Example: Web page should load in 3 seconds.

In systems engineering and requirements engineering, a non-functional requirement is a requirement that specifies criteria that can be used to judge the operation of a system, rather than specific behaviours. They are contrasted with functional requirements that define specific behavior or functions

Example of non functional requirement: After entering the login credentials by the user  to login into the system, how much speed the system take in order to login represents non functional requirement.
Example: once login to any site we should go to another page within 3 sec.

What are non Functional Rquirements;

Non-functional requirements are also known as quality or supplementary requirements. They capture conditions that do not directly relate to the behavior or functionality of the solution. These can include requirement related to capacity, security, speed, availability and the information architecture and presentation of the user interface. Non-functional requirements may also describe aspects of the system that don't relate to it's execution, but rather to it's evolution over time (e.g. maintainability, extensibility, documentation, etc).   
Types of Non-functional Requirement :

1)   Scalability
2)   Reliability
3)   Regulatory
4)   Maintainability
5)   Serviceability
6)   Utility
7)   Security
8.)   Manageability
9)   Data Intergrity
10)   Capacity
11)   Regulatory
12)   Availability
13)   Usability
14)   Interoperability
15)   Environmental

Non- Functional requirement are the attributes of the requirements such as scalability, security, availability, reliability integrity and many more

Non-functional requirements refers to quality or supplementary requirements. While analyzing the requirements once gathered, all the non functional requirements will be collected and prepares supplementary support document.  Environmental conditions under which the solution must remain effective or qualities that the systems must have.
The below are the non functional requirements:
capacity
stability
-speed
-security
-availability and information
-architecture and
-presentation of user interface
efficiency
reliability

Non-functional requirements are often called "quality attributes" of a system. Other terms for non-functional requirements are "qualities", "quality goals", "quality of service requirements", "constraints" and "non-behavioral requirements". Qualities that is non-functional requirements can be divided into two main categories:

    Execution qualities, such as security and usability, which are observable at run time.
    Evolution qualities, such as testability, maintainability, extensibility and scalability, which are embodied in the static structure of the software system

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. Also known as system qualities, nonfunctional requirements are just as critical as functional Epics, Capabilities, Features, and Stories. They ensure the usability and effectiveness of the entire system. Failing to meet any one of them can result in systems that fail to satisfy internal business, user, or market needs, or that do not fulfill mandatory requirements imposed by regulatory or standards agencies.  In some cases, non-compliance can cause significant legal issues (privacy, security, safety, to name a few). NFRs are persistent qualities and constraints that, unlike functional requirements, are typically revisited as part of the Definition of Done (DoD) for each Iteration, Program Increment (PI), or release. NFRs influence all backlogs: Team, Program, Solution, and Portfolio. Proper definition and implementation of NFRs is critical. Over-specify them, and the solution may be too costly to be viable; under-specify or underachieve them, and the system will be inadequate for its intended use. An adaptive and incremental approach to exploring, defining, and implementing NFRs is a vital skill for Agile teams.

Non-Functional Requirements are the constraints or the requirements imposed on the system. They specify the quality attribute of the software. Non-Functional Requirements deal with issues like scalability, maintainability, performance, portability, security, reliability, and many more. Non-Functional Requirements address vital issues of quality for software systems. If NFRs not addressed properly, the results can include:
1. Users, clients, and developers are unsatisfied.
2. Inconsistent software.
3. Time and cost overrun to fix the software which was prepared without keeping NFRs in mind.

Non-functional requirement
 A non-functional requirement is a requirement that specifies criteria that can be used to judge the operation of a system, rather than specific behaviours.
Non-functional 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
Non-functional requirements are constraints imposed on the system. They're used to define the quality attributes which will determine how the system operates. Their main purpose is to make the product (application, software, website, or other) run more efficiently and thus improve the user experience.
NFR capture the conditions that do not directly relate to the behaviour or functionality of the solution but rather describe environmental conditions under which the the solution must remain effective or qualities that the system must have
