OSI model

Model with 7 layers to describe communications systems The Open Systems Interconnection model (OSI model) is a conceptual model that characterizes and standardizes the communication functions of a telecommunication or computing system without regard to its underlying internal structure and technology. Its goal is the interoperability of diverse communication systems with standard protocols. The model partitions a communication system into abstraction layers. The original version of the model defined seven layers. A layer serves the layer above it and is served by the layer below it. The model is a product of the Open Systems Interconnection project at the International Organization for Standardization (ISO). Communication in the OSI-Model (example with layers 3 to 5) History[edit] In the late 1970s, the International Organization for Standardization (ISO) conducted a program to develop general standards and methods of networking.

Buckaroo Banzai Handbook undefined A Guide to the film: The Adventures of Buckaroo Banzai Across the 8th Dimension. 10 Ways 'Buckaroo Banzai' Has Infiltrated Pop Culture [Movies] This handbook serves as a guide for those who want to venture into the BB world and don't have anyone to walk them through it, because the first time you see it it's a bit confusing. When I've shown the film to friends, I usually have to pause midway in order to explain the plot. There are those fortunate ones, however, who do understand and enjoy the film during the first viewing. For the rest of us, here's a reference guide: Cast: Peter Weller, John Lithgow, Ellen Barkin, Jeff Goldblum, Carl Lumbly, Christopher Lloyd and Clancy Brown. As brief a summary as I can muster: Buckaroo Banzai takes that story and moves it one step further, leading the audience to believe that Orson Welles had been brainwashed by those aliens into lying to the audience about the "hoax". These Red Lectroids are outlaws in their own planet. Characters of Note: Dr.

HL7 normalizando la comunicacion en salud Hablar del estándar HL7 es difícil, no solo por su complejidad estructural (ya que está formado por varios estándares), si no porque también es difícil elegir el enfoque. Para este artículo me voy a concentrar en el modelo de referencia de HL7, en el modelo de documentación clínica, y en aspectos conceptuales que me gustaría destacar y/o criticar de forma constructiva para ayudar a quienes encaran un proyecto usando HL7. Introducción Health Level Seven (HL7) no es un estándar en sí, si no que es un conjunto de estándares cuyo principal objetivo es especificar mensajería para la comunicación de información clínica, demográfica y financiera, entre sistemas informáticos. Existen algunos estándares dentro de HL7 que tienen otros focos, pero la mensajería es uno de los aspectos más fuertes de HL7. HL7 tiene su origen en los EEUU, y sus estándares reflejan el modelo de atención en ese país. Los principales estándares que conforman a HL7 son: ¿Qué no es HL7? ¿Qué veremos en este artículo?
