After asking around, i was told that. webcam is nothing more than a digital camera. The 'webcam' function is actually done by computer.

so, is it true that when the camera captures a frame its actually send each color data of each pixel to the computer via usb until it forms a picture in the computer? If, so what is the sequence of sending each pixel? meaning to say top to bottom or left to right or zig zag?

Thank you.

*i've done googling and wikipeding and still continuing searching but at the mean time i haven't get the answer i need
