Kumdo and Kendo are virtually the same martial art with some minor differences. Generally, Kumdo is considered a Korean variant of Kendo and Korean martial artists even participate in the Kendo World Cups. It's argued wether Kumdo developed from ancient Korean swordmanship or simply imported from Japanese Kendo, but in general, both are considered one and the same.
Kendo
Kendo uses, I believe, the same belt grading system common throughout Japan. Like in Judo and Karate at the black belt level there are "Dan" grades. Pretty much the same grading system used in Judo and Karate (10th to 1st kyu and 1st to 10th Dan*), the only real difference is that in kendo usually there's no difference in belt colour or anything like that, there's no way one can tell the difference between a begginer and an experienced kendoka just looking at the clothes. *Nowadays, 8th Dan is the highest rank possible in kendo, since there are no more 9th or 10th Dan holders alive.
