How long does it take to update all nodes that have the blockchain so that they are identical?

How long does it take to update all nodes that have the blockchain so that they are identical?

Beginner questions...

I understand that everybody has their own copy of the blockchain.

If one person makes a change, for example a transaction, I assume that it has to propagate to all other nodes. How long does this take?

How does a node know that the update process is complete throughout the blockchain?

What algorithm is used to synchronize and what is its order (O())?
