Client tier is actually a 3 tier hierarchical structure which includes cliet tier, application tier and data tier.
A distribution system typically separates an application into three tiers: the presentation tier, the application tier, and the data tier. The presentation tier is responsible for the user interface and user experience, enabling interaction with the application. The application tier contains the business logic and processes data between the presentation and data tiers. Lastly, the data tier manages data storage and retrieval, ensuring efficient access to the underlying databases.
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
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).

A tier-2 application typically refers to software that operates within a multi-tier architecture, specifically the second layer that interacts with the user interface (tier-1) and the database or backend services (tier-3). This layer handles business logic, data processing, and communication between the user interface and the database. In essence, tier-2 applications serve as intermediaries that manage data flow and processing logic, ensuring that user requests are appropriately handled and results are returned efficiently.
3-Tier
Sigle tire means using single technique to built entier application. For Example only using jsp for building whole web application instead of using jsp, servelt and database.
Single-tier architecture is the notion of having the user interface of a web application, the middle ware and the data access all contained in one whole architecture. Usually in Software Engineer you break your application to make them more maintainable and sustainable. If you know that your software will not grow over time, you may want to do a single tier architecture.
They are mission critical applications...eg It could be Exchange server, Database Server etc
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.
Cab tier is a non permanent electrical cord used for hooking up machinery. If the machinery is deemed a "non permanent" machine cab tier is generally used unless deemed unsafe due to "traffic". Basically in laymen's terms an extension cord.
In Veloci-Q's three-tier structures, the sections typically consist of the presentation layer, the application layer, and the data layer. The presentation layer handles the user interface and user experience, the application layer processes business logic and application functionality, and the data layer manages data storage and retrieval. This separation of concerns enhances scalability, maintainability, and performance of the overall system.
