What is the advantage of n tier architecture?
Maintenance. N-tier architecture can improve the maintenance of your software since different people can manage single tiers without influencing the management of other tiers. This can help ensure that the appropriate person is responsible for a given tier.
What is the component of n tier architecture?

These are the presentation tier, processing or logic tier, and data tier: The presentation tier is responsible for presenting information in a format that can be easily understood and manipulated by the user.
What is the difference between n-tier architecture and MVC?
MVC abstracts away the details of how the architecture of an app is implemented. N-tier just refers to the physical structure of an implementation. These two are sometimes confused because an MVC design is often implemented using an N-tier architecture.
What is N tiered software?
N-tier data applications are data applications that are separated into multiple tiers. Also called “distributed applications” and “multitier applications”, n-tier applications separate processing into discrete tiers that are distributed between the client and the server.
What is the difference between n-tier and n layer?
N-Tier refers to the actual n system components of your application. On the other hand, N-Layers refer to the internal architecture of your component. N-Tier architecture usually has atleast three separate logical parts, each located on separate physical server. Each tier is responsible for a specific functionality.
What is the difference between two tier and n-tier architecture?
The second tier is responsible for providing the availability, scalability, and performance characteristics for the organization’s web environment. In an n -tier architecture, application objects are distributed across multiple logical tiers, typically three or four.
Is MVC is a 3 tier architecture?

Why is it called hexagonal architecture?
The term “hexagonal” comes from the graphical conventions that shows the application component like a hexagonal cell. The purpose was not to suggest that there would be six borders/ports, but to leave enough space to represent the different interfaces needed between the component and the external world.
What is client and server with example?

What is the difference between MVC and MVVM?
KEY DIFFERENCE
