Answer to Question 1

Apache HTTP Server has dominated the Web since it became widely available because it is free, performs efficiently, and has a large number of knowledgeable users who contribute technical advice to online discussion forums, wikis, and blogs. Apache runs on many operating systems (including FreeBSD-UNIX, HP-UX, Linux, Microsoft Windows, SCO-UNIX, and Solaris).
A number of companies sell support services for Apache for organizations that want the additional security; however, most Apache installations are supported by the organizations own technical staff using the free online help that is available.

Answer to Question 2

Architectures that have more than three tiers are often called n-tier architectures. N-tier systems can track customer purchases stored in shopping carts, look up sales tax rates, keep track of customer preferences, update in-stock inventory databases, and keep the product catalog current.
