What is the difference between NMR and qNMR?

Could you please clarify the distinction between NMR and qNMR for me? I understand that both are techniques used in analytical chemistry, but I'm not sure how they differ in their applications, accuracy, or any other key aspects. Is one technique more suitable for certain types of analyses than the other? I'd appreciate any insights you could provide to help me better understand the differences between NMR and qNMR.
