A company has installed an application that only requires a workstation to function. Which of the following architecture types is this application using?
Correct Answer: A
One-tier architecture is a type of architecture that uses only one layer or tier for an application or system. In one-tier architecture, the application logic, data, and user interface are all contained within the same layer or tier. One-tier architecture would be the best description of a technology that allows an application to run on a workstation without requiring any other components or layers. Two-tier, three-tier, and n-tier architectures are types of architectures that use more than one layer or tier for an application or system. In two-tier architecture, the application logic and data are separated into two layers or tiers. In three-tier architecture, the application logic, data, and user interface are separated into three layers or tiers. In n-tier architecture, the application logic, data, and user interface are separated into multiple layers or tiers.
