What is Open Systems Interconnection Basic Reference Model (OSI Reference Model or OSI Model)

The word “convergence” refers to the combination of fixed and mobile communication, a situation where a private or business user can take advantage of being constantly connected and be able to retrieve applications and data by swapping device, with the limitations that a mobile device may have such as smaller screen and keyboard, reduced storage capability, and limited power provided by batteries. Convergence can also include imagining how mobile technology can be a component of everyday items and how data, applications, and services can be delivered via the network infrastructure. This chapter aims to cover RFID technology, Bar code and Service-Oriented Architecture (SOA): the first two technologies are dealt with in parallel to provide an overall view of advantages and disadvantages, while SOA will be part of a distinct discussion and analysis. Eventually, some practical examples of these discussed technologies are provided.
