This is another installment in the blogging terms you need to know series.
Menu – A menu is made up of the pages on your blog. The menu on my blog has 6 pages. Depending on your theme you may have a primary navigation bar and a secondary navigation bar where the menu(s) is located. My blog has both and I will explain each of them.
Background – You can choose to have a background on your blog. I do not recommend a background as it distracts your readers from your content.
