Final answer:
The two types of knowledge articles available are wiki and markdown, used for collaborative editing and text formatting, respectively.
Step-by-step explanation:
The two available knowledge article types are wiki and markdown. A wiki is a collaborative space where users can create and edit interconnected pages. Markdown is a lightweight markup language with plain text formatting syntax that can be converted to HTML or other formats. For example, the basic format for citing a journal article in a database as per academic standards would be:
Author's Last Name, First Name. "Title of Article." Title of Journal, volume number, issue number, Date of Publication, page numbers. Title of Database, DOI or URL.
This standard is crucial for students when researching and writing academic papers, ensuring that articles accessed through databases are appropriately credited.
