What is a presentation layer?
The computer network frame consists of seven distinctive layers. These layers were well defined by the model of open standards (OSI). The presentation layer represents a layer of six in the OSI model. It is a network layer that is responsible for transforming messages into comprehensible computers in the network.
Computer networks are responsible for connecting computers and hardware via telecommunications devices. This spider network of connection requires a translation service that can transform messages into an understandable format for each type of device. The presentation layer converts messages to multiple formats to support multiple devices. This translation service allows a transmission computer to communicate without any problems with a smartphone in one computer network.
The presentation layer is also responsible for encryption and decrypting information from computer devices. This layer must send and receive messages from ltiple muspecification and direct them over the network. Computer encryption usuallyIt depends on internal specifications for organization. The security process is managed in this OSI network tank layer. The presentation layer can improve performance using special compression processes. This requires algorithms that can be used to reduce the size of messages sent via the network, increasing the permeability and performance. The presentation layer of the mesh model is responsible for all algorithms and processes of decompression.
Many people confuse the presentation layer with the implementation of the application screen. This is because the date of presentation is usually synonymous with screen design in most discussions about information technology. Inside Network Architecture, the presentation layer is basically associated with the presentation of the message format and is not related to the design of the screen
Technical implementation of specific tasks in the presentation layer can be implemented in the application layer of the OSI model. This is because many commercial prodThe Ukt was committed by the network tasks of the layer of six and seven for one implementation. In addition, many tasks performed in the presentation layer are not unnecessary for most reports transmitted via the network.
A good example of this layer in a practical application is to secure the transmission protocol of Hypertext (HTTPS). HTTPS is an encrypted protocol that is usually used on the Internet. While HTTPS is considered to be the application layer interface, it interacts directly with this layer for encryption algorithms. This is because the presentation layer is responsible for decrypting encrypted network messages.
