UI stands for User Interface. It is the point of human-computer interaction and communication in a device, system or software. It involves the design of the graphical layout of an application. It consists of the buttons users click on, the text they read, the images, sliders, text entry fields, and all the rest of the items the user interacts with. This includes screen layout, transitions, interface animations and every single micro-interaction. Any sort of visual element, interaction, or animation must all be designed.

The way a user interacts with an application refers to how a user can control and operate the application. This can be through various input devices such as a keyboard, mouse, touch screen, etc. The design of the UI should be intuitive and easy to understand to provide a user-friendly experience.

What a user interacts with in an application refers to the various elements of the UI. These can be buttons, sliders, text fields, checkboxes, etc. The user uses these elements to interact with the application.

The results of a user's interaction with an application refer to the outcomes of the user's actions. For example, if a user clicks on a button to save a document, the document gets saved. This is the result of the user's interaction.

Feedback from a user's interaction with an application refers to the responses or reactions the application provides to the user's actions. For example, if a user tries to save a document and the document gets saved successfully, a message saying "Document saved successfully" might appear. This is feedback from the application to the user.
