When taking notes from a lecture, a student should

rely on a recording device

Explanation:

A lecture is the oral presentation of certain ideas by someone. When a student wishes to take lecture notes he should use a recording device because the speaker will not stop talking to wait for the student to take notes of everything he or she deems important. For this reason, while the student writes an annotation, the student may lose some information, this information will be recorded by the recording device, so that the student will have access to all the information, later.
