The functions of presentation layer are :
1. Data transcription
2. Data reconstruction
3. Data Encryption and Decryption
4. Data compression
Networks has the ability to connect many servers on the same single network. The presentation layer is constructed for uncertainty while transferring data between networked systems.
Presentation layer also implement bit order reversal functions. It converts carriage return data to carriage return with line feed data and it also converts integers to floating point numbers.
The presentation layer decreases the number of bytes for transmission,
