    no reply because u can get these information in documentation easily. but i think u don't want to try hard. any way -

    this information comes from dba_tab_columns. it is for backward compatibality with orace7.

    low_value - low value in that particular column
    high_value - high value in that particular column

    you have missed out the column name in your output. the information stored is in raw format . hence 'C102' . you can check this by -

    select min(column_name) from table_name
    and then

    select rawtohex(yourvalue) from dual;

    you will get C102 .
