Web Technologies: Its use for compression and decompression of the file size. Data Compression, by reducing the number of bits requiring transmission, which improves the data throughput. The presentation layer may represent (encode) the data in various ways (e.g., data compression, or encryption), but the receiving peer will convert the … » Content Writers of the Month, SUBSCRIBE Residing at Layer 6 of the Open Systems Interconnection (OSI) communications model, the presentation layer ensures that the communications that pass through it are in the appropriate form for the recipient application. Presentation layer functions This layer is concerned with preserving the meaning of the information sent across a network. Sometimes, the presentation layer is also known as syntax layer. Because data can be communicated using different formats, platforms and sources, presentation layer is responsible for integrating all of the formats into an acceptable and compatible form. » Node.js We also covered CASE and SASE, the sub-layers used to aid the presentation layer, as well as how the presentation layer translates data into a form usable by the application layer. Presentation Layer Protocol –ASCII, EBCDIC, ICA, LPP, NCP, NDR, AFP etc 3. An encryption algorithm is used during transmission, while a decryption algorithm is used at the receiving node. The main functions of the presentation layer are as follows − It encodes the messages from the user dependent format to the common format and vice versa, for communication among dissimilar systems. Aptitude que. The presentation layer translates data between the formats the network require and the formats the computer expects. The encrypted data is known as the cipher text and the decrypted data is known as plain text. What is JavaScript Object Notation (JSON)? » C At key points on drawing objects b. Encrypt, format and compress the data for transmission. » SQL As layer six of the OSI model, the presentation layer is primarily responsible for managing two networking characteristics: protocol and architecture. In the OSI model: the presentation layer ensures the information that the application layer of one system sends out is readable by the application layer of another system. Encoding data in a standard agreed-upon way just like a string, double, date, etc. Under this condition presentation layer plays a role translator. As computer-literate as you are, you may not know what the presentation layer, or data translator, has to do with paying your bills. Languages: Decryption concerned with the transform of the message back to its original form. » Embedded Systems The presentation layer works to transform data into the form that the application layer can accept. Enrolling in a course lets you earn progress by passing quizzes and exams. Submitted by Monika Jha, on October 04, 2019. Anyone can earn Some common data formats handled by the presentation layer include the following: » C What is a REST Web Service? This layer is a part of the operating system that converts the data from one presentation format to another format. Specific functionalities of the presentation layer are as follows: 1) Translation The processes or running programs in two machines are usually exchanging the information in the form of numbers, character strings and so on before being transmitted. first two years of college and save thousands off your degree. : » Facebook - Definition & Examples, What is an IP Address? Run-length encoding (find/print frequency of letters in a string), Sort an array of 0's, 1's and 2's in linear time complexity, Checking Anagrams (check whether two string is anagrams or not), Find the level in a binary tree with given sum K, Check whether a Binary Tree is BST (Binary Search Tree) or not, Capitalize first and last letter of each word in a line, Greedy Strategy to solve major algorithm problems, Languages that are syntax can be different from the two communicating machines. The Presentation Layer negotiates the Transfer Syntax. Thus, the presentation layer is responsible for integrating all formats into a standard format for efficient and effective communication. These seven OSI layers are in descending order (top layer to bottom layer) and each layer provides inputs and outputs to/from the neighboring layers. The presentation layer does protocol conversion, data translation compression and encryption. Compression: Compression (and decompression) may be done at the presentation layer to improve the throughput of data. Log in or sign up to add this lesson to a Custom Course. Communication with the application layer above. The presentation layer's basic function is to convert the data intended for or received from the application layer into another format.

The Presentation layer at the receiving machine changes the common format into its receivers dependent format. It Performs Standard Encoding scheme on the wire. & ans. Before we begin our discussion of the presentation layer in greater detail, let's introduce the networking environment in which the presentation layer exists: this is the Open Systems Interconnect (OSI) model, which has seven layers, and each layer performs a specific and supportive communicative task. Handles the structuring of data and negotiating data transfer syntax to Layer 7. © copyright 2003-2020 Study.com. Presentation Layer The Presentation Layer represents the area that is independent of data representation at the application layer - in general, it represents the preparation or translation of application format to network format, or from network formatting to application format. » C Data Conversion: This is where the presentation layer performs bit order reversal functions, converts CR (byte code for a carriage return) to CR/LF, (byte code for a carriage return with a line feed) and converts integer numbers to floating point numbers. Data can be communicated in different formats via different sources. Languages (syntax) can be different of the two communicating systems. Character-Code Translation: Where the presentation layer translates from the American standard code for information interchange (ASCII) to the extended binary code decimal interchange code (EBCDIC).
