Which is not a form of written communication?

The correct answer is that conference calls are not a form of written communication. Conference calls primarily involve verbal communication, where participants engage in discussions and share information in real-time through audio or video means. This mode of communication is interactive and relies on spoken dialogue rather than written documentation.

Emails, patient charts, and memos, on the other hand, represent various forms of written communication. Emails consist of text-based messages exchanged electronically, allowing for documentation of correspondence. Patient charts are written records that detail patient information, treatment plans, and health history, ensuring accurate and comprehensive documentation for healthcare providers. Memos serve as brief written messages used to communicate important information within an organization, often providing updates or instructions. Thus, while all the other options involve written forms of communication, conference calls do not align with that definition.
