48 1.4 How “Technical” Writing and “Professional” Writing are Related and How they Differ
Technical communication—or technical writing—is writing about any technical topic. The term “technical” refers to specialized knowledge that is held by experts and specialists. Whatever your major is, you are developing an expertise and becoming a specialist in a particular technical area. And whenever you try to write or say anything about your field, you are engaged in technical communication.
Professional (or business) writing, on the other hand, covers much of the additional writing you’ll be doing in your profession. Professional writing includes correspondence such as emails, memos, newsletters, business letters, and cover letters, as well as other documents such as resumes, social media posts, blogs, and vlogs. While professional writing may convey technical information, it is usually briefer and targets an individual or small group of readers who may or may not be experts in the field.
