What is the primary function of the Presentation Layer?

• A. Routing data
• B. Translating data formats and ensuring readability
• C. Providing end-user network services
• D. Managing sessions

Answer: (B)

Data representation and translation between systems is what the Presentation Layer focuses on. It ensures that data created by an application on one host can be interpreted correctly by an application on another host, even if their native formats or character sets differ. This involves translating data formats and ensuring readability, such as converting between different encodings or data structures. While compression and encryption can be associated with this layer, the central task is making the data understandable across systems. Routing data is handled by the Network Layer, providing end-user network services falls to the Application Layer, and managing sessions is handled by the Session Layer.
