What is an external identifier?

All records in the database have a unique identifier, the id field, that is a sequential number automatically generated by the database engine.

Since we don't know these IDs beforehand (and we can need them to reference a related record), we use external named identifiers to translate these identifier names into the actual database IDs assigned to them.

The ir.model.data keeps the mapping between the named external IDs and their corresponding numeric database IDs.
