What role does the Presentation layer (layer 6)of the OSI model play in terms of data compression and encryption? The Presentation layer is primarily responsible for the physical encryption of data using hardware-based methods. The Presentation layer is involved in the logical organization of data into frames for transmission. The Presentation layer handles the routing of data between different networks and supports encryption protocols like IPsec. The Presentation layer supports data compression and encryption to prepare data for network transmission.
