The innovative advancements of information communication technology (ICT) combinedwith a globalized economy have given rise to organizational forms that manipulate timeand distance. Today, competitive advantages are more elusive than tangible as a result ofdynamically complex environments motivating organizations to adjust in structure andfunctional capacity. New emergent forms of organizational structures have resulted inthe virtual organization (VO), which employs a network structure and allowsorganizations the flexibility to perform core processes amongst distributed teams, units,departments, and/or organizations. In essence the virtual organization may be viewed asa strategic response to dynamic environmental forces that have encouragedorganizations to rethink the concept of competitiveness. Virtual organizations havegained popularity throughout the last decade as a more effective way of managing andcommunicating information within and across organizations. Information communicationtechnology (ICT) has aided in the globalizing effect of informationalism. Theinformational flows within a virtual organization have direct bearing on individual andgroup efforts to obtain and employ information essential to organizational objectives.This thesis investigates the information interchange within virtual organizations througha theoretical study, which converges identified relevant subject areas and introduces theMedia Rich Social Information Interchange (MERiSii) model. The empirical study isdesigned to further investigate the validity of theoretical concepts employed in theMERiSii model and to expand its development to facilitate the function of informationinterchange. VGR-IT is an IT infrastructure provider, for hospitals and healthcarefacilities in the Västra Götaland region of Sweden. Interviews conducted with an accountmanager for VGR-IT and an IT strategist for Borås Hospital give insight into thecommunicative tasks of information interchange that must be effective to support the coreprocesses within VGR-IT and the service VGR-IT provides to Borås hospital. The resultsof a comparative analysis between the theoretical and empirical studies support a revisedMERiSii model that may be implicated in future research to further verify itseffectiveness. / Program: Magisterutbildning i informatik

Virtual networks have changed the face of the information technology in current world. Many organizations today cooperate in virtual networks in order to meet the competition and the increased demands on technological development. Our focus in this thesis is on the information interchange in inter-organizational virtual networks. In this case the problem is related to the efficiency of the virtual networks for information interchange. This paper aim is to identify and discuss the possible aspects in the virtual networks efficient information interchange. This paper provides the detail information about the security aspects and its improvement and use of the efficient information interchange in inter organizational virtual network. This paper also provides the information that is helpful for improving the security in the virtual network so that the work in virtual network or the work via virtual network is efficient. / Program: Magisterutbildning i informatik

The Internet is a collection of computer networks; it is the most important networkingenvironment in the world, it used for information interchanges in virtual network. Wirelesstechnologies, such as Wi-Fi, WiMAX etc, can suggest more suitable and cooler way forinformation interchanges in virtual network.The most well-known ongoing wireless city projects are counting Wireless Philadelphia, GoogleWi-Fi Mountain View, Wireless Taipei City, and San Francisco Tech Connect project. Web haslimits of interactivity and presentation. The Web’s client-server architecture blocks informationexchange. Furthermore, most Web applications are only intended for conservative computers,not for mobile handheld devices. In period of information exchange on the Web, the new Web2.0 is suggested. Web 2.0 refers to a perceived or planned second generation of Internet-basedservices, such as public networking sites, wikis, communication tools, which highlight onlineteamwork and sharing among users.A virtual network or online community is a collection of people that may or may not chiefly ororiginally connect or interact via the Internet. Virtual network have also become an additionalform of communication amid people who know each other in actual life. Today, virtual networkcan be used insecurely for a diversity of social collections interacting via the Internet. It does notunavoidably mean that there is a solid bond between the members.The validation methods like internal validity, external validity and Reliability for this researchand how it affects these methods for our research. We also use interview method has beenconsidered for this research. We will use diagrams, models, prototypes, and texts, to illuminate our result. We will define allthe diagrams and models and prototypes in my own text. We will give the reference of theoriginal data collected from various sources where as from Internet, websites, books andJournals. / Program: Magisterutbildning i informatik
