Questiontransaction recovery Pin

The quote below is from *An Introduction to Database Systems, 8th edition, C J Date*.
Is that possible systems crash while transferring the updates from physical device to database?
"It is quite possible, for instance, that the system might crash after the COMMIT has been honored but before the updates have been physically written to the database--they might still be waiting in a main-memory buffer and so lost at the time of the crash. Even if that happens, the system's restart procedure will still record those updates in the database: it is able to discover the values to be written by examining the relevant records in the log."
