What does it mean by deleting your Facebook account and how do you do that?

[J]

How can I completely delete my Facebook account? How to delete all those posts, comments on my friend's walls and all uploaded photos? Will deleting your Facebook account delete everything you ever posted on anyone's wall? Even if their your blocked list or not on your facebook friend list anymore?
Thank you very much

All of your photos and post will be on the internet forever but go to your fb settings and go to deactivate account

everything will stay on the internet but your account will not be able to be seen or accessed. go to settings and hit disable account. your account can be reactivated at any time by simply loging back in. it will reactivate everything and save all your old settings and profile info

You can deactivate your account. If you deactivate (settings-deactivate acc) your account, facebook will hide all the info related to your account. When you login again to your account the previous settings are restored to your account.
You can also DELETE your account, deleting your facebook account means facebook will erase all the info related to your facebook account. To delete your facebook account goto facebook help, type 'delete facebook account'. Then a link will appear to delete your account.
