What layer of the Open Systems Interconnect (OSI) model provides a variety of coding and conversion functions applied to application layer data?

• A. Transport
• B. Presentation
• C. Session
• D. Network

Answer: (B)

Data representation and encoding for applications are handled by the layer that performs coding and conversion functions to ensure the application layer data is understood at the receiving end. This layer takes care of translating data into a common format, handling character encoding, and applying data compression or encryption as needed so that the application can interpret the information correctly regardless of the underlying systems. In addition to formatting and encoding, it may also manage other transformation tasks so that the data presented to the applications is consistent and usable. This is why it fits best: the other layers focus on transport reliability and delivery (Transport), managing dialogue and connections (Session), or routing and addressing across networks (Network).
