Decentralized Exchange is a trading platform that allows free peer to peer transactions without a regulatory body. Thanks to blockchain technology which is an open ledger that has a proven security, convenience and fast transactions in decentralized exchange.
Here, transactions are faster because there is no middleman or third party that makes approval before the said transaction is carried out. No middleman/permission, bureaucratic bottlenecks. The user is in full control of his/fund and can operate anonymously.

Centralized Exchange is the direct opposite of decentralized exchange. It entails a trading platform that has a regulatory body with it's terms and conditions to operate in there platform. This third party is in full control of the funds, they approve or disapprove any transaction. You cannot operate anonymously here because of kyc.
In otherword, the middlemen authenticates all the transactions and of course along with it's charges.
