The correct answer should be N-tier, single tier, 2-tier, 3-tier
N-tier = distributed "mutiple" tiers kinda obvious
Single tier = "all client" needs updating because of business logic or data model (DB) change
2-tier = presentation and business logic intertwine (together), assuming the DB separate server
3-tier = presentation and business logic in common (assuming separate) server; DB separate server
