Notes are short pieces of information that help us remember important details. They can be written on paper or stored digitally on devices like smartphones and computers. People often take notes during lectures, meetings, or while reading to capture key points and ideas. This practice makes it easier to review and study later. In addition to helping with memory, notes can also be used for organizing thoughts. For example, students might create study notes to prepare for exams, while professionals might jot down meeting notes to keep track of discussions. Overall, notes are a valuable tool for learning and communication.
