presentation layer

Do you want to learn about the presentation layer and need to know it in detail? Then just take a pause and read about it here. I will explain all of the information that is related to this layer. You will get a brief idea regarding the establishment of it. I will describe further the functions, applications, services, etc that you will come to know. So let us start to read what is the presentation layer definition.

What Is Presentation Layer?

The presentation layer is the layer 6 th number layer in the OSI layers of the open systems interconnection. This layer of the presentation is used for presenting the data to the application layer that is the 7 layer of the OSI model. It helps in defining the data in a good format. This layer is also called as syntax layer. The OSI model Presentation layer helps in representing the data that is received in it from the session layer.

Presentation Layer Functions

There are some of the functions that we have mentioned in the following for you, please read them.

  • It receives data from the session layer.
  • It helps in the translation process.
  • This does the encryption of the data.
  • It does the data compression to reduce its bandwidth.
  • The layer also does graphic handling.
  • This shares the data with the application layer.

Presentation Layer Services

You will get the following services by presentation layer OSI model:

  • Data conversion
  • Character code translation
  • Compression
  • Encryption and Decryption
  • Serialization

Applications Of Presentation Layer

In the following, you will come to know about the application of presentation 6 th layer of the OSI model.

  • It helps to get free from the data representation that is encryption.
  • It is used for the translation process between the application and network formats.
  • It does the data transformation which is being accepted by the applications.
  • It formats and encrypts the data to be sent.

Presentation Layer In Osi Model

The OSI presentation layer in the model is located on the 6th number. It works for defining the data format and encryption. It is responsible for the transfer and processing of information to the application layer for further analysis or display. This method of service is needed because different computing architectures use different data representations for processing. It manages all the issues that are related to the data presentation and transport. It also sees the work of translation, encryption, and compression. In further presentation layer protocols in the psi model will be explained to you.

Challenges with Presentation Layer

In the following, you will see what challenges are faced by it.

  • It helps in managing the transmitted information Syntax and Semantics.
  • The data is encoded in a standard because of it.
  • It performs a standard encoding process on a wire.

Presentation Layer Protocols

Below we have mentioned the different protocols of the presentation layer examples. So read each of them carefully.

  • Apple Filing Protocol (AFP)
  • Independent Computing Architecture (ICA)
  • Lightweight Presentation Protocol (LPP)
  • NetWare Core Protocol (NCP)
  • Network Data Representation (NDR)
  • Telnet (a remote terminal access protocol)
  • Tox works in both the presentation and application layer
  • eXternal Data Representation (XDR)
  • Packet Assembler/Disassembler Protocol (PAD)

Presentation Layer Vs Application Layers

Here is the difference between the layer of presentation vs the application layer that we have mentioned in the following. You will come to understand the difference in both after reading it.

  • The layer of presentation is the 6th layer of the OSI model. While the application layer is the 7th layer of the OSI model.
  • The 6th layer does the work of encryption, translation, and compression of the data. The 7th layer of the file transfer, networking, host initialization, etc.
  • In the presentation, layer data is received from the session layer. However, the application layer receives the data from the 6th layer.

FAQ

What Is The Function Of The Presentation Layer?

Here are some of the functions that we have mentioned in the following:

  • It receives data from the session layer.
  • It helps in the translation process.
  • This does the encryption of the data.
  • It does the data compression to reduce its bandwidth.
  • The layer also does graphic handling.
  • This shares the data with the application layer.

What Is The Difference Between The Application Layer And The Presentation Layer?

Below we have mentioned the difference between the presentation layer and the application layer 

  • The layer of presentation is the 6th layer of the OSI model.  While the application layer is the 7th layer of the OSI model.
  • The 6th layer does the work of encryption, translation, and compression of the data. The 7th layer of the file transfer, networking, host initialization, etc.
  • In the presentation, layer data is received from the session layer. However, the application layer receives the data from the 6th layer.

What Are The Protocols Used In The Presentation Layer?

Here are the protocols that are used in the layer of presentation.

  • Apple Filing Protocol (AFP)
  • Independent Computing Architecture (ICA)
  • Lightweight Presentation Protocol (LPP)
  • NetWare Core Protocol (NCP)
  • Network Data Representation (NDR)
  • Telnet (a remote terminal access protocol)
  • Tox works in both the presentation and application layer
  • eXternal Data Representation (XDR)
  • Packet Assembler/Disassembler Protocol (PAD)

What Is The Presentation Layer In A Web Application?

In a web application, the layer of presentation is a simple component of the three-layer model. You will come to know that it is the front-end layer for the application. This is one main component that is Graphical User Interface. It helps users by allowing them to interact with the application. This provides the access to the functions and services.

Conclusion

The information on the presentation layer that you read above is useful for you. The functions, services, etc are the important points that I explained to you in simple language. After reading it you understood the information. You came to know about the different protocols of the 6th layer. You also read the difference between it and the application layer. So now you have come to know of the presentation layer and what does it do.
