Information Architecture (IA) components include organization systems, navigation systems, search systems, and labeling systems. There are two basic forms of IA: top-down forms like the UNSW homepage that are organized from a broad overview; and bottom-up forms like Google that are organized based on user needs and searches. Questions ask about distinguishing organization from labeling systems, which IA form is suitable for different websites, and why searching systems usually provide the information users are looking for.
