CHAPTER 5: Network Applications, Web 2.0, Distance Learning, and Telecommuting Computer
Networks to Connected computers in order to work together, are interdependent, and exchange data with each other. Three size Computer Networks are, Home computer network, National computer network, and Global computer network. And they are four Network Applications. First, Discovery, it allows users to browse and search data sources, in all topic areas,on the Web. It includes Search engines which are computer programs that search for specific information by key words and report the results. And Metasearch engines search several engines at once and integrate the findings of the various search engines to answer queries posted by users. Portal is a Web-based, personalized gateway to information and knowledge that provides relevant information from different IT systems and the Internet using advanced search and indexing techniques. Commercial (public) portals offer content for diverse communities and are the most popular portals on the Internet. Affinity portals support communities such as a hobby group or a political party. Mobile portals are accessible from mobile devices. Corporate portals offer a personalized single point of access through a Web browser. Industrywide portals are for entire industries.
Second Network Application is Communication, it include Electronic mail (e-mail) is the largest-volume application running on the Internet, Web-based call centers (customer call center) are services that provide effective personalize customer contact as an imporant part of Web-based customer support, and Electronic chat room is a virtual meeting place where groups of regulars come to “gab”. Unified communications simplifies and integrates all forms of communications – voice, voice mail, fax, chat, e-mail, instant messaging, short message service,presence (location) services, and videoconferencing – on a common hardware, and software platform.
Third, Collaboration refers to efforts of two or more entities (individuals, teams, groups, or organizations) who work together to accomplish certain tasks. Work group refers specifically to two or more individuals who act together to perform some task. Virtual group (team) is when group members are in different locations. Virtual collaboration is the use of digital technologies that enable organizations or individuals to collaboratively plan, design, develop, manage and research products, services and innovative applications. Web 2.0 is a loose collection of information technologies and applications, and the Web sites that use them. The this is the most well-known Web 2.0 meme map, by Tim O’Reilly. He goes into more detail than Markus Angemeier. Depending on how much detail you want to go into, this figure provides any level of detail that you need.
