Answer:
It is important to add presentation layer after the physical layer, so that the data along with it's headers can be translated, when the receiver machine is applying a set of different characters.
Data compression is also required to reduce the space that is occupied by data during transmission, now once the presentation is added to the physical layer, data from the physical layer can be compressed at the presentation layer and sent by improving the throughput.
Explanation:
Solution
The presentation of data involves the following as shown below:
Presentation of data comprises of the task like translating between receiver and sender devices so that machines with different capabilities sets can communicate with one another.
It involves encoding and decoding of data to provide data security that is been transmitted by different machines.
Data sometimes needs to compressed for efficiency improvement for transmission.
The physical layer of the TCP/IP protocol suite is responsible or refers to the transmission of physical data over a physical medium
It is good or important to add presentation layer after the physical layer, so that the data along with it's headers can be translated, when the receiver machine is applying a set of different characters.
Data encryption at this stage is good for security instead of encrypting the data at upper/higher layers.
Hence, it is advisable to add presentation layer after the physical layer in the TCP/IP suite.
