Types of requirements

• Functional — It is required for the system’s function(They are must for operation)
  FaceBook

• User login for the system(Authentication)

• Adding posts

• Commenting

• Liking the post

• Non Functional — It is not required directly, but it is required circulatory.

• Allow users to use either mouse or keyboard

• Allow user to change focus

• Providing feedback

User requirements and System requirements

• User Requirements — The requirements that users need, in natural language

• Functional : Account create, Account Login

• Non Functional : Dark Mode, Loading speed, Ads, Animation

• System Requirements — The requirements that need for the system’s function

• Functional : Login data secure, Should be able to register a customer

• Non Functional : Ability to change the mode
