exchange
The process in which one thing is exchanged for another, usually without using money. It is a direct giving and taking.

The exchange of trading cards in the schoolyard is very popular with the children.
The noun 'der Tausch' (the exchange) is derived directly from the verb 'tauschen' (to exchange/swap). The noun describes the action expressed by the verb.
Wollen wir die Plätze tauschen?
Shall we swap seats?
When describing what is being exchanged, the preposition 'gegen' (for/against) is crucial. The structure is often: 'der Tausch von [thing A] gegen [thing B]' (the exchange of [thing A] for [thing B]).
Der Tausch seines alten Fahrrads gegen ein neues Smartphone war ein gutes Geschäft.
The exchange of his old bicycle for a new smartphone was a good deal.
The expression 'im Tausch gegen' (in exchange for) is a fixed unit and is always used with the accusative. It expresses what you receive as compensation for something else.
Er bekam das Buch im Tausch gegen seine Hilfe beim Umzug.
He got the book in exchange for his help with the move.

'der Handel' and 'der Tausch' both have to do with giving and receiving. 'der Handel' usually means buying and selling, that is, an economic activity in which money often plays a role. It can also mean an individual deal or agreement. 'der Tausch' means that one thing is given directly for another thing, usually without money. Learners may confuse the words because both describe a kind of exchange. When money, goods, and business dealings are important, 'Handel' fits. When two things are exchanged directly for each other, 'Tausch' fits.
Der Tausch war fair: Tom gab sein Buch und bekam dafür ein Spiel.
The exchange was fair: Tom gave his book and got a game in return.
