JARGON BUSTER:

Nav bar
Shorthand for 'navigation bar' - a set of links to all the main sections of a site. Top level navigation
This should appear on every single page and be consistent in both style and location.

Generally, people expect to find the main navigation somewhere at the top of the page - placing it anywhere else means people may not immediately see all the choices available.

Always make sure that it's 'above the fold' sp that users won't have to scroll down to find it. Subsidiary Navigation.
This displays links to the content available within each subsection. Secondary Navigation
This is made up of other navigational aids like links to the site map and contact page, search boxes, drop down lists etc



BLUFFERS GUIDE

'Information architecture'
Phrase used by Japanese lager-drinking, Hoxton Fin-toting designers to describe the process of planning a site by analysing its content, functionality and purpose.

Or, in other words, working out what you want the chuffing thing to do before you start building it.
