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 OSI Model NTC/360 Network & Telecommunications Concepts The OSI Model The Open Systems Interconnection Reference Model (OSI) is the accepted model that describes the how the communications for a computer network should be designed. OSI was developed as part of the Open Systems Interconnect Initiative. Basically‚ OSI divides the functions of a protocol in to seven layers. This makes the reasoning easy to follow and the system much more reliable. The implementation of several OSI layers

The multifactorial model in health psychology is a leading paradigm that recognizes the multi-faceted nature of illnesses. It is not a clear-cut‚ simple case that a disease is caused by a singular factor. The fact is that decades if not over a century of modern research has led to the recognition that a host of factors‚ as well as their interactions‚ function in illness and health determination (Nevid & Rathus‚ p. 126). These varied factors that the multifactorial model indicates to be the range

It is a process that attempts to match observation with symbolic statement. A mathematical model uses mathematical language to describe a system. Building a model involves

Consistency Models1 David Mosberger TR 93/11 Abstract This paper discusses memory consistency models and their influence on software in the context of parallel machines. In the first part we review previous work on memory consistency models. The second part discusses the issues that arise due to weakening memory consistency. We are especially interested in the influence that weakened consistency models have on language‚ compiler‚ and runtime system design. We conclude that tighter interaction between

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

and unique talent. When thinking of the topic of role models the very first person who comes to mind‚ is that of a professional athlete. There are a lot of arguments arising on whether or not athletes should be considered role models. Many believe that a role model must be someone who has a personal relationship or bond with one another; however‚ a role model is someone who an individual aspires to be. Sports figures are admirable role models both on and off the field although mass media portrays
