What do the numbers and letters like "Knight C 3" mean?

That is chess notation - the language of chess!

The letters and numbers describe a location on the board that the piece is moving to! This way, you can tell the story of a game simply through the letters and numbers describing where each piece moves! Some advanced players can visualize a game entirely in their head just by reading the chess notation!
