The blockchain can be compared with the network that banks have with each other. The difference is that with the banking network only the banks have insight and control over all transactions (central) and with a blockchain everyone has insight and control over the transactions (decentralized).
Anyone who downloads the blockchain software on his computer becomes a participant of the network. All these linked computers check whether transactions are correct. If more than half of these computers agree, the transaction is approved.
A transaction is sent from one wallet to another. A wallet can be compared to a bank account. The blockchain can be seen as an archive in which everyone can find the history of the transactions.
