Rook chess math task - proof-writing

On a chessboard with 8 × 8 squares, a rook threatens all the chess pieces in the
the same line or the same column in which it stands, regardless of whether another
rook stands in between or not!!

How many rooks can be placed on the chessboard maximally so that each tower
threatens at most two more rooks?

What does "tower" mean?

Are you assuming two sides (black and white) where threats are only to opposing pieces?
