The end users are able to operate at the _______ tier.
Answer Details
End users are able to operate at the "presentation" tier.
The presentation tier is the user interface layer of a software application or system. It's the part of the system that the end user interacts with directly, and it includes all the components that allow the user to view and manipulate data. This can include things like graphical user interfaces, web pages, and other visual elements that the user can see and interact with.
Because the presentation tier is designed specifically for end users, it's the layer that they are most comfortable operating in. This is where they can view data, input information, and interact with the system to achieve their desired tasks. While there may be other tiers (such as the model, application, and data tiers) that are responsible for processing and managing data behind the scenes, it's the presentation tier where the end user has the most control and where their actions have the most direct impact on the system.
