Collection represents a group of NFTs. Historically NFTs were grouped by smart-contracts which were considered as collections. Later on appeared projects which allowed minting NFTs in the same contract so one contract could contain several collections. Or vice-versa, sometimes several smart-contracts contain NFTs from one collection
