+#  6. Presentation Layer
+The presentation layer is responsible for preparing the data so that it can be used by the Application Layer. 
+
+**Presentation layer is responsible for:**
+- Translation of data
+- Encryption of data
+- Compression of data
+
+For example, two devices can use different types of encoding on their data, the presentation layer will translate the data in a way that the Application Layer can understand.
+
+When sending sensitive data, we would like to encrypt the data so that its secure. The Presentation layer is responsible for encrypting and decrypting ingoing or outgoing data.
+
+Also when sending of receiving data we sometimes want to compress the data so that sending and receiving data is more efficient. (smaller size)
