An app instance is a file that's type points to an app. Similar to a class instance in object oriented programming.
Components are the no-code equivalents of apps. It is used to create reusable elements or element structures, typically via drag-and-drop. A component wraps one or more app or component instances and optionally declares some input files to be defined at component instances.
For example, a page component may define a page layout to have a certain menu and footer, but the contents should not be the same on all pages (instances of that page component), rather defined individually.
Components are mostly implemented in kernel space but they require certain functionality to be defined in user space. These are defined in the component app.
The file type of components points to this component app.
A component instance is similar to an app instance but for components.
Component instances encapsulate the inner structure of the referenced components and present them as single objects. Only the input parameters of the component (input files) can be defined at the component instance level.

.Requestmethod is executed on the requested file. System defined methods start with an uppercase letter after the dot, user defined methods start with a lowercase letter after the dot.
.Requestis located on its type chain and executed.
.Requestis reserved for request method files.
A section is an input file container. Apps and components may define such sections to parameterize certain file inputs for their instances.
For example, page apps and page components will typically define at least one section for page contents. That way, users can drop contents in these sections on individual pages.
A section placeholder is used to define a section within a component.
Sections are mostly implemented in kernel space but they require certain functionality to be defined in user space, particularly for section placeholders. These are defined in the section placeholder app.
The file type of section placeholders points to the section placeholder app.
