apachebench (ab) and concurrency (-c)

I was using ab for some very simple load testing.

$ ab -n100 http://192.168.34.6/hits.php
Generates 100 access log lines.

$ ab -n100 -c100 http://192.168.34.6/hits.php
Generates *roughly* 200...


Huh? I guess I don't understand what '-c' does...

Can anyone explain?
