What are parallels and meridians? what do they serve?

parallels and meridians are imaginary lines on the surface of the Earth, and latitude and longitude (in degrees, minutes and seconds) are their coordinates, which determine the position of points on the surface of the Earth. Any point on Earth is the intersection of a parallel and a meridian with latitude and longitude coordinates.
