Layer 6: presentation layer

The presentation layer is layer 6 and serves as the data translator for the network. 

It is sometimes called the syntax layer.

The presentation layer is responsible for the following:

• Data encryption/decryption
• Character/string conversion
• Data compression
• Graphic handling

The presentation layer mainly translates data between the application layer and the network format. 

Data can be communicated in different formats through different sources. 

Thus, the presentation layer is responsible for integrating all formats into a standard format for efficient and effective communication.
