Well, this is my memories,not certainly true. So I surfing the internet and found the true meaning of journals (i think).Anyways this article was taken from http://en.wikipedia.org/wiki/Journal.here is the thing:
A journal (through French from Latin diurnalis, daily) has several related meanings:
- a daily record of events or business; a private journal is usually referred to as a diary.
- a newspaper or other periodical, in the literal sense of one published each day;
- many publications issued at stated intervals, such as magazines, or scholarly pacific journals, academic journals, or the record of the transactions of a society, are often called journals. Although journal is sometimes used, erroneously], as a synonym for "magazine", in academic use, a journal refers to a serious, scholarly publication, most often peer-reviewed. A non-scholarly magazine written for an educated audience about an industry or an area of professional activity is usually called a professional magazine.
The word "journalist" for one whose business is writing for the public press has been in use since the end of the 17th century.
Quite impressive eh,it looks my thought of learnings is only half true.Then there exist the fact of various kind of journals.Of course it aims to educates people .
