Decentralized means not controlled by any single entity or institution. Blockchain is an example of something that is decentralized, all full nodes in the network own a copy of the blockchain. And not just a single entity (which would make it centralized). In a decentralized system, if one node goes down, the rest of the network continues to operate without hiccups.
