presentation layer example

The presentation layer of the Open System Interconnection (OSI) model is responsible for how that data looks or is formatted. This is responsible for presenting the data to the application layer in an accurate, well defined and standardised format. Answer: The responsibilities taken by these two layers are completely optional and subject to change as per requirements. Encryption is typically done at this level too, although it can be done on the application, session, transport, or network layers, each having its own advantages and disadvantages. Presentation layer protocol is the 6th layer of the OSI model. [1] Decryption is also handled at the presentation layer. The sixth layer is the Presentation Layer in the OSI model. If a connection is not used for a long period, the session-layer protocol may close it and re-open it. Network (e.g. This layer deals with issues of string representation - whether they use the Pascal method (an integer length field followed by the specified amount of bytes) or the C/C++ method (null-terminated strings, e.g. IP, routers) 4. This is the last and the topmost layer of the OSI model. The benefits of having n-tier architecture is that all the modules having dedicated functionality will be independent of each other. Physical (e.g. Here are the steps for building the Presentation Layer into an OBIEE Repository : Checksum Error Detection Tutorial With Example, Different Network Topology Tutorial With Example, Probability Formulas, Examples With Solutions, Subnetting And Subnet Mask Tutorial With Example, Introduction to Threads in Operating System, Network Layer Protocol Tutorial With Example, Inter Process Communication In Operating System, Hamming Code And Hamming Distance Tutorial With Example, Physical Layer Protocol Tutorial With Example, Pie Chart Questions And Answers With Examples, IP Header Protocol Structure With Example, Volume Of Solids (Cube, Cuboid, Prism, etc.) The presentation layer can be composed of two sublayers: common application service element (CASE) and specific application service element (SASE).[5]. Likewise, this layer translates information from the application layer to the session layer. MAC, switches) 3. cable, RJ45) 2. It is sometimes called the Syntax Layer.The main responsibilities of the presentation layer protocol are: Q. The presentation layer translates information in a way that the application layer understands. It is sometimes called the Syntax Layer. Layered application designs are extremely popular because they increase application performance, scalability, flexibility, code reuse, and have a myriad of other benefits that I could rattle off if I had all of the architectural buzzwords memorized. For example, when logging on to bank account sites the presentation layer will decrypt the data as it is received. Not just that, this layer controls the single or multiple connections for each end-user application, and is responsible for directly communicating with both the presentation and the transport layers. Syn/Ack) 6. Sometimes, the presentation layer is also known as syntax layer. This form is nothing but the Presentation Layer. Application Layer c. Network Layer d. Transport Layer Answer. The session layer manages any session by initiating the opening and closing of sessions between end-user application processes. Two common examples are 'objects' in object-oriented programming, and the exact way that streaming video is transmitted. As The session layer supports full-duplex and half-duplex operations and creates procedures for checkpointing, adjournment, restart and termination. HTML defines a bunch of different HTML elements known as tags that are put together to make up the basic layout of a web page. Building the Presentation Layer of the OBIEE Repository. As well as simple pieces of data, like strings, more complicated things are standardized in this layer. The business layer maintain… Data Link (e.g. Thus, it is left to application to decide if it requires the layer or not. The main responsibilities of the presentation layer protocol are: Presentation layer responsible for the delivery and formatting ofinformation to the application layer for furtherprocessing or display is the lowest layer at which application programmersconsider data structure and presentation, instead ofsimply sending data in the form of datagrams orpackets between hosts An example of a presentation service would be theconversion of anEBCDIC-coded textcomputer fileto anASCII-coded file. Figure 1: The BLL Separates the Presentation Layer from the Data Access Layer and Imposes Business Rules. The data layer manages the physical storage and retrieval of data 2.
