Non Functional Requirement: As the name says, so is the meaning. When a functionality tends to be a feature of the application, the opposite being non-functional can be termed as focusing on functionality's behavior.
When every functional requirement says, "action" to be done, while every non-functional requirement defines the quality to be delivered of that functionality.
For ex: We have a functionality, "Admin should be able to view all the orders in the system"
Some non-functionality requirements samples could be,
1) Performance - In what time should the system take to load the data?
2) Usability - Is the screen usable enough for the end user?
3) Security - How secured are we in showing the customer data?

Usually, the non-functional requirements would be defined by client or in some organizations, they define a standard for themselves and follow them.

A non-functional requirement describes a feature or trait that a business solution must have, but that is not directly related to the core business functions of the solution.
