FreeBSD newbie Problems

[ananth_G]

hi all,
im new to freeBSD. ive been using linux( mostly redhat and mandrake, and
slackware) , lately i have moved to unix. 
i have a few things to be cleared

what are the startup script files that get executed during boot?
httpd gets started automatically in the system i work. i tired searching
/etc/rc.conf , but i couldnt find an entry for httpd. is there any other
startup script?

regrds,
Ananth.G
