Working mechanism of framerates

Hello Everyone,

Currently i am interfacing a camera which operates at frame rate 120 fps at resolution of 640*480 I am using Opencv to interface the camera.I haven't set any parameter for the camera so inorder to get the frame rate i am using the following link and which gives me 30fps. https://www.learnopencv.com/how-to-find-frame-rate-or-frames-per-second-fps-in-opencv-python-cpp/

So various question comes to me which i am not able to get the answers correctly. 1. What is the difference between the framerate of the hardware camera and my software program. 2. Can i call the frame rate captured by the software as the framerate of the camera. 3. If frame rate of the camera is different so how can i sync both the frame rates. 4. Exactly how does video capture works.

New to opencv so need to get clarity before proceeding. Thanks.
