a hot wallet is a wallet that is unlocked on a machine that has a kind of network connectivity - think of the wallets the exchange sites use, or the wallet you use on you phone or computer
a cold wallet is stored "offline" on a paper or on a computer that is not having a network connection (the term comes from cold storage in fact)

It's a matter of speed, the hot wallet immediately has the possibility of exchanging for flat money (in many cases depending on the app used) in the case of cold wallets, the security of the funds is the main thing.
