Which layer of the OSI model is responsible for data encryption?

• Data encryption and decryption


• Data compression


• Character code translation (e.g., ASCII to EBCDIC)

Encryption at this layer ensures that data is securely encoded before it is transmitted across the network, making it unreadable to unauthorized parties.

Explanation of other layers:

• Session Layer: Manages sessions between applications.


• Transport Layer: Provides reliable data transfer with error checking and flow control.


• Application Layer: Interfaces directly with the user and applications, but not responsible for encryption itself.
