Seven Layer OSI

DOWNLOAD On this occasion we will discuss about the OSI. Why for an expert network should know about OSI, because basically the OSI concept is the basic concept that gave rise to the development of computer networks. The following overview of the OSI we cuplik of https://sites.google.com/site/net9com. When the technology first emerged, network a computer usually can only communicate with other computers that are derived from the same manufacturers. The OSI model made by the International Organization for Standarization (ISO) to solve thecompatibility issues between different vendors, device by providing standardizationwhich can be used by the vendor in making the device, so the device-device originating from different manufacturers can still support each other (compatible). A reference model is a concept that describes how communication is supposed to do. Model reference identifies all processes needed to communicate and share themlogically into groups called layers. The OSI reference model is a reference model orone of the network architecture. OSI describes how data and information network to communicate from an application on a computer passes the network media to the aplikaksi who are on the other computer. Seven Layer OSI The main goal of every model the OSI model, in particular reference is to allow device-devices from different manufacturers can operate. Other advantages include: !Download! Divide the complexity contained in the network Changes that occur on one layer does not affect all the layers. This can allow developers specialise in building an application. As a consequence will speed up the process of the development of a system. Mendefenisikan standardization of interface so that between each other can integrate manufacturing. The OSI reference model does not explain the physically, but is a guide for application developers in creating and implementing its applications running on a network.OSI is also a framework in the making and implementing of standard network, device and network planning (internetworking scheme). OSI 7 layer, which is generally divided into two groups namely the Upper layer (Application layer) and the Lower Layer (Transport Layer Data). Layer that belongs in theupper layer mendefenisikan how applications on a host will communicate with the user and host of others. While the lower layer mendefenisikan how the data sent from one host to another host. The OSI reference model consists of seven layers, among others: The Application Layer Presentation Layer Layer Sesion The Transport Layer Layer Network Data Link Layer Physical Layer Source: https://sites.google.com/site/net9com Overview of the discussion above is a general overview about the OSI reference model is the OSI we discuss on the next post. Hopefully this brief article can provide benefits for those of you who are learning the basics of the concept of computer networks.
