what is mean by schema less in No SQL?

I am just a beginner in No SQL, while learning I saw its schemaless. Yes, I understand if I have to insert data, the data structure is not required on No SQL (without creating tables or collection), but other than that what it differs from SQL in the case of schemaless? In SQL I can add new fields to table with queries and No SQL can also do that.

Please advise if I am miss understand the concept and help me get this answer. Thanks in advance
