To answer this question, we need to understand the differences between 2-tier and N-tier applications.
A 2-tier application consists of a client and a server. The client is responsible for the presentation layer, while the server handles the application logic and data storage. This architecture is simple and easy to implement but may suffer from performance issues as the load increases. Scaling a 2-tier application typically involves scaling the entire server, which can be inefficient and costly.
On the other hand, an N-tier application is a distributed system that separates the application into multiple tiers or layers. Each tier has its own responsibilities and can be scaled independently. The most common N-tier architecture is the three-tier architecture, which consists of a presentation tier, an application tier, and a data tier.
Modularity in N-tier applications allows for better performance because each component or tier can be scaled individually. For example, if the application tier is experiencing high load, additional application servers can be added to handle the increased load without affecting the other tiers. Similarly, if the data tier is facing performance issues, additional database servers can be added to handle the increased data processing.
Therefore, the statement "N-tier applications show better performance than 2-tier applications because they are modular in nature and can be scaled easily by tuning components and containers individually" is true.
The correct answer is A) true.
