Data Reformatting: When two computers exchange data, the data is changed to bit streams before it is transmitted. Encryption/ Decryption : Data encryption translates the data into another form or code. At key points on drawing objects b. » C The first function is: Third, the presentation layer is responsible for: The fifth function of the presentation layer is: Other protocols supported at the presentation layer include: Get access risk-free for 30 days, » C 's' : ''}}. It translates between Application and other layers, redirects, encrypts and compresses messages. » Contact us Earn Transferable Credit & Get your Degree, Session Layer of the OSI Model: Functions, Protocols & Examples, Network Layer of the OSI Model: Functions, Design & Security, Application Layer of the OSI Model: Definition, Functions & Protocols, Transport Layer of the OSI Model: Functions, Security & Protocol, Physical Layer of the OSI Model: Definition, Components & Media, Application Layer Protocols: Types & Uses, Data Link Layer of the OSI Model: Protocol, Functions & Design, OSI Model: Using Open Systems Interconnection to Send and Receive Data, Cables for Networking: Types & Characteristics, Physical & Logical Topology: Definition & Characteristics, What is Communication Protocol? » DS In other words, the presentation layer takes care of any issues occurring when transmitted data must be viewed in a format different from the original format. » SQL Visit the Information Systems: Tutoring Solution page to learn more. - Tools & Overview, What is User Experience? Services. It is responsible for data encryption and decryption of sensitive data before they are transmitted over common channels. This allows for data to be transported between devices and still be understood. The following functions are performed by this layer: Encryption/Decryption: A system must be capable of assuring privacy for carrying sensitive information. Encoding data in a standard agreed-upon way just like a string, double, date, etc. Log in or sign up to add this lesson to a Custom Course. » PHP In this lesson, we introduced the Open Systems Interconnect (OSI) model, which has seven layers that each perform a specific and supportive communicative task. An encryption algorithm is used during transmission, while a decryption algorithm is used at the receiving node. This layer also handles data functions such compression, encryption, decryption, etc. The presentation layer's basic function is to convert the data intended for or received from the application layer into another format. : The encrypted data is known as the cipher text and the decrypted data is known as plain text. - Definition & Explanation, What is Hypermedia? It also helps you to handles data compression and data encryption. The Presentation layer performs certain functions that are requested sufficiently often to warrant finding a general solution for them, rather than letting each user solve the problems. 1 The _______ layer lies between the session layer and the application layer. On a seperate layer c. Every time when one clicks on the screen d. Only in model space, Working Scholars® Bringing Tuition-Free College to the Community, Establishes, manages and terminates communicative sessions, Provides reliable process-to-process message delivery and error recovery, Moves packets from source to destination by providing inter-networking capabilities, Organizes bits into frames, providing node-to-node delivery, Transmits bits over a medium, establishing mechanical and electrical specifications. The design should from the application layer rather than the presentation layer. » Java The presentation layer also encrypted your account login information prior to transmission.
