The utopia is a word borrowed from Thomas More. It designed a world which is a perfect society in which everyone works well with each other and is happy.
Instances : L'Ile des Esclaves by Marivaux
Whereas, a dystopia is the contrary of utopia. It is an imaginary society that offers a potical and social system that prevent people from reaching happiness.
Instances : Brave New World by Aldous Huxley and 1984 by Georges Orwell
