COMPUTER NETWORKING

Detailed explanation-1: -Encryption and decryption of data communications are also performed at the presentation layer. Here, encryption methods and keys exchange between the two communicating devices.

Detailed explanation-2: -This ensures the security of the data as it travels down the protocol stack. For example, one of the most popular encryption schemes that is usually associated with the presentation layer is the Secure Sockets Layer (SSL) protocol.

Detailed explanation-3: -The presentation layer transforms data into the form that the application accepts. This layer formats and encrypts data to be sent across a network.

Detailed explanation-4: -Encryption and decryption Because computer systems often handle sensitive information, the presentation layer performs both of these important security tasks. On the sender’s end, the layer encrypts the transmitting data before it enters session layer.
