i see "{}" in various commands around here what is there funtion?

IE:

find / -type f -exec grep email@host {} /dev/null \;
or
find /home/domains/*/ -type d -exec chmod 777 {} \;


is the {} \; part of the -type funciton?

this is what i understand about the following commands.

1) start the find at the root dir.
a) only looking for flatfiles
b) grep for email@host in any matches from the find
?c?) the output for the find fills the namespace {}?
d) /dev/null is used to so the output of the whole command lists filename then search pattern
e) \; why the backslash the line is not continueing and why they semi-colon.
