mysql USER unclear about what can be dropped?

When show databases there is the information_schema listed below it detailing my developed data sources yet what is 'USER' and also 'mysql' detailed in there?

I do not recognize if ages ago I slipped up and also developed them or if they are default listings which disclose something?

The data sources information_schema and also mysql exist by default. information_schema has valuable details concerning the standing of your mysql web server and also the storage space engines you are making use of, it reads just. The db mysql shops particular arrangements of your MySQL web server, like for exmample the customers and also their password hashes, it is editable.

I do not assume the db USER that you are stating is just one of the default dbs, to make sure that would certainly need to have actually been developed by you.
