Which layer is responsible for data translation and encryption in Open System Interconnection (OSI) model of Internet?
Answer: D
Data translation and encryption are handled by the presentation layer.
The presentation layer, layer 6 of the seven-layer OSI model, translates data between the application's format and the network format, and handles encryption, decryption and compression.
The transport layer (4) provides end-to-end delivery and error recovery, the network layer (3) handles routing and logical addressing, and the data link layer (2) handles framing and physical addressing.
