Client tier is actually a 3 tier hierarchical structure which includes cliet tier, application tier and data tier.
A tier-1 ISP connets to all other tier-1 ISP's; a tier-2 ISP connects to only a few of the tier-1 ISPs. Also a tier-2 ISP is a customer of one or more tier-1.
Tier 1 Internet providers are the largest ISP of the world, forming together the backbone of the Internet. Like many end-users, ISP's usually have their own ISP, from which they purchase bandwith. These are lower tier ISP's. Tier 1 ISP's do not have ISP's in their turn, but rely solely on their own resources to carry data around the world.
Client-Server model is a form of 2 Tier architecture in PHP. With use of database it becomes a 3 Tier architecture
In 3 tier architecture, client directly interacts with intermediate server and intermediate server will directly interact with database server.
Data centers are used to house computer systems such as those for telecommunications and storage. A tier 4 data center is used mainly for information that requires high security or stringent environmental requirements.
Client tier is actually a 3 tier hierarchical structure which includes cliet tier, application tier and data tier.
Both of them are application development tools from Oracle One of the difference is Oracle forms 4.5 uses two tier technology ie it is client server based. It needs the Oracle client to run Oracle forms 9i uses uses three tier technology ie the application developed using it runs on an internet brower.

Three-Tier Architecture of Data WarehouseClient:-* GUI/Presentation logic* Query specification* Data Analysis* Report formatting* Data accessApplication/Data Mart Server:-* Summarizing* Filtering* Meta Data* Multidimensional view* Data accessData Warehouse Server:-* Data logic* Data services* Meta data* File services
the client is on the first tier. The database server and web application server reside on the same server machine, which is the second tier. This second tier serves the data and executes the business logic for the web application
Traditional architecture was monolithic: one big program, running on a mainframe. Then, two tier (two layers) architecture came, with PCs talking to servers, both having some intelligence (applications versus data). Then three tier architecture arrived, powered by internet technology, Java and .Net. Data, applications and presentation are separated in this architecture. Presentation is almost always in a browser, the application and the data run on servers, usually in the corporate data center or somewhere 'on the internet'.
gdg Web applications are stored on a server and delivered to users over the Internet. A Web application is usually a three-tier structure, comprising a User Service tier (allowing user access to the application), a Business Service tier (allowing the user to carry out complex activities) and a Data Service tier (which allows data storage and retrieval). An application that conforms to the Java 2 Platform Enterprise Edition specification. publib.boulder.ibm.com/infocenter/ws51help/topic/com.ibm.websphere.exp.doc/info/exp/glossary.html Web applications are stored on a server and delivered to users over the Internet.

In single tier architecture, a single executable file handles all functions related to user,business and data services.like the case of PASCAL,COBOL.
Military Personnel Data System. A tier 0 military front end to access and update personnel data including pay and leave.
N-tier software architecture refers to a method of designing a system. In this system, the presentation, application processing, and data management are logically done separately from each other.
