What is a key role of the Presentation Layer in the OSI model?

The Presentation Layer in the OSI model serves a critical function in ensuring that data is presented in a format that can be understood by both the application layer and the network layer. This layer is responsible for translating data formats between different systems; for example, it can convert character encoding (like from ASCII to EBCDIC) or compress data to optimize the transmission process.

This translation process allows diverse systems to communicate effectively by ensuring that the data sent by one application is in a format that can be understood by another, regardless of the underlying architecture or operating system. By handling these format concerns, the Presentation Layer plays a pivotal role in enabling interoperability among different networked applications.
