Uploading various content for the course may be done using components. Once the course designer has created the required sections and subsections, they must create units to insert the content within. The components are included within the units; with the help of these components, we can upload the course contents of our choice.
The components that are included within units by default are HTML, Video, Problem, Discussion, and Open Response.
Also, the setting’s options enable us to add other components, altering the default components.
