Which tier in the N-tier application architecture is responsible for moving and processing data between the tiers?

Answer options

• A. Presentation tier
• B. Application Layer
• C. Logic tier
• D. Data tier

Correct answer: C

Explanation

The Logic tier is responsible for the processing and movement of data between the various layers of the N-tier architecture, making it the correct answer. The Presentation tier focuses on user interface, the Application Layer handles application logic, and the Data tier is responsible for data storage, thus they do not perform the data processing and movement functions.
