The 7 Layers of the OSI Model Last updated: March 03‚ 2008 The OSI‚ or Open System Interconnection‚ model defines a networking framework for implementing protocols in seven layers. Control is passed from one layer to the next‚ starting at the application layer in one station and proceeding to the bottom layer‚ over the channel to the next station and back up the hierarchy. |Application |This layer supports application and end-user processes.

Selecting the right model for your online business warrants careful consideration because each model requires different skills and time commitments to operate. Not all models will suit you or compliment your business interests

History of the OSI Reference Model Looking at the origins of the OSI Reference Model takes us back to several issues that were discussed in the Networking Fundamentals chapter of this Guide; specifically‚ I am talking about standards and standards organizations. The idea behind the creation of networking standards is to define widely-accepted ways of setting up networks and connecting them together. The OSI Reference Model represented an early attempt to get all of the various hardware and software

Subject: Dell’s Direct Business Model Date: 04/08/05 Will Dell’s direct business model continue to provide a competitive advantage as fellow competitors Compaq‚ IBM‚ and HP emulate Dell’s direct model? Dell’s direct business model bypasses the dealer in the supply chain and sells computers directly to customers‚ building each to order. Dell does not manufacture the computer components; they merely assemble computers based on components that are available in the market. Dell’s use of technology

The Lean Startup Model The Lean Startup model is a scientific method designed to help businesses get the desired product to customers faster by shorterning the product development cycle. Lean manufacturing‚ which has been around for decades‚ aims to create more value with fewer resources. However‚ what if a company was efficient at creating a product that was not in demand? Proposed by Eric Ries in 2011‚ this model is a combination of hypothesis-driven experimentation‚ iterative products and validated

Each row contains a single record comprised of individual data elements (or "attributes") organized in columns containing elements of the same kind according to the rules defined for that column. Alternate database models include the network‚ hierarchical‚

The WB-PBPK model for caspofungin was constructed according to the scheme of 14 tissue compartments of the disposition model. Simulations were based on caspofungin physicochemical and the vitro data (Table 2). Tissue distribution was predicted using established tissue composition equations. Hepatic and renal caspofungin clearances were calculated by the PKplus model‚ as described in the method section. The results are shown in Table 3. The observed and WB-PBPK model simulated mean plasma concentration-time

Energy resources Energy resources are stores of convertible energy. These resources are divided into two groups: Non renewable resources which include fossil fuels (e.g. coal‚ oil and gas) and nuclear fuels. Renewable resources‚ which include wind‚ tidal‚ geothermal‚ and hydroelectric power. Non renewable sources Are used in thermal power stations to produce heat energy that turns water into steam. The steam drives turbines and in turn drives the generators that produce electrical energy. Fossil
