OSI Model Joshua M. Grooms The Open Systems Interconnection model‚ or the OSI model‚ is a way to sub-divide a communications system into smaller‚ more manageable parts known as layers. A layer is a grouping of functions that have similar purpose that either provide services to the layer above it or receives services from the layer below it. On which layer of the OSI model do WAN protocols operate? WANs are managed by the protocols that exist in level 2‚ the Data Link Layer‚ of the OSI

Introduction The waterfall model is the most common model of all software development life cycle models. It is very simple to understand and use. In a waterfall model‚ each phase must be completed before the next phase can start. At the end of each phase‚ a review takes place to determine if the project is on the right path and whether or not the project should be continued. Here phases do not overlap with each other. Waterfall model is a sequential design process in which progress is seen

The Open Systems Interconnection (OSI) model (ISO/IEC 7498-1) is a conceptual model that characterizes and standardizes the internal functions of a communications system by partitioning it into abstraction layers. The model is a product of the Open Systems Interconnection project at theInternational Organization for Standardization (ISO). The model groups similar communication functions into one of seven logical layers. A layer serves the layer above it and is served by the layer below it. For example
