Technical Writing in my words

When I think of the word technical, I think of having knowledge of a mechanical, scientific, or any specific field. When I think of writing I think of putting symbols together on some surface to form words. So if I were to think of technical writing I would think about putting symbols together to form information within, about, or pertaining to the field that a person has knowledge. As a Computer Science major the above definitions fits in perfectly with my profession and with me personally.
