Technical Principles of the Internet
{"Image DocumentName": "Technical Principles of the Internet", "Image ImageDescription": "Communications systems such as the Internet are best described using layered models because of their complexity. Every layer within the model has a certain task, and all layers together produce a particular communication service for the user. The layers are arranged in hierarchical form. Layers lower in the hierarchy produce a service used by the higher layers. The uppermost layer finally combines all lower layer services and constitutes the interface for applications. For the Internet, the so-called Internet reference model is used and is shown on the next slide.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
