They are mission critical applications...eg It could be Exchange server, Database Server etc
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
Chennai is tier 1 but Madras is tier 2
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.
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.
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).

Metro Cities are called Tier 1
"Tiers" are the item levels. Potions at Tier 1 restore less HP then those of Tier 2. Tier 1 potions heal 250 HP while those of Tier 3 can heal 1250. Basically, the higher the tier the stronger that item is.
3-Tier
In Automotive manufacturing a Tier 1 contracts and supplies material / parts direct to an OEM ( Original Equipment Manufacturer), A Tier 2 sells to the Tier 1 and the Tier 3 sells to the Tier 2.
Tier 1 is the top tier... this would includes groups such as Delta Force, SEAL Team 6, 22nd SAS Regiment, etc.
