keeping blog entries only on blog page

Typically, when installing wordpress, the blog entries [along w/ the categories, archives, comments,] are kept along the sidebar for every page of the site.

How would I go about ensuring that the blog entries are just kept on the sidebar of the blog section and the other pages are free of this?

I tried to do a search but couldn’t find it as I guess I’m not using the right keywords to search for.

if there is a good thread that can point me to this, that would be helpful. thank you.
