This document discusses network computing concepts including the internet, intranets, extranets, and various tools for communication and collaboration over networks. It explains that the internet links computing resources globally using TCP/IP protocols. Intranets and extranets allow internal and partner communications. Discovery tools like search engines, software agents and portals help access information. Communication occurs through email, chat and social networks. Collaboration is supported by workflows, groupware and real-time tools that allow shared editing. Web applications also enable distance learning and telecommuting.

- 20. Information inForeign LanguagesInternet Application Category…DISCOVERYThe Internet contains information with various languagesAutomatic translation tools are provided by manyRemoves language barrier for easier discovery
- 21. Information &Corporate PortalsInternet Application Category…DISCOVERYWhat is a portal?Personalized gateway to information and knowledge in network computingAvoids information overload by providing one screen from which we do all our work on the WebThis eliminates retrieval time spent on integrating disparate IT systems
- 22. Information &Corporate PortalsInternet Application Category…DISCOVERY7 Typesof portals:Commercial / Public PortalsOffer content for diverse communities and interestsAlso the most popular portals on the InternetE.g.

- 35. COLLABORATION TOOLSWORKFLOWSWhat are Workflow Technologies?Movement of information through the sequence of steps that make up an organization’s work procedures or business processesWorkflow ManagementThe automation of workflows from start to finish, including all exception conditionsWorkflow SystemsBusiness process automation tools (software programs) that automate almost any information-processing task
- 36. COLLABORATION TOOLSWORKFLOWSWorkflow ApplicationsCollaborative WorkflowProject oriented and collaborative types of processes e.g. sharing / centralized updatesProject Management Systems e.g. LotusProduction WorkflowAddresses mission-critical, transaction-oriented, high volume processesE.g. Database access, data entry, data storage & retrievalAdministrative WorkflowIs cross between collaborative and production workflows e.g. admin systems (APIIT)Reduce clerical costs
- 37. COLLABORATION TOOLSGROUPWAREWhat are Groupwares?Software products that support groups of people who share a common task or goal and who collaborate on its accomplishment.Groupware implies the use of networks to connect people, even if the people are in the same room Groupware Tools / ApplicationsElectronic Meeting SystemsImprove face-to-face meetings
- 38. COLLABORATION TOOLSGROUPWAREElectronic TeleconferencingAllows two or more people at different locations to have a simultaneous conferenceVideo Teleconferencing - participants in one location can see participants at other locations. Data (data conferencing) can also be sent along with voice and video making it possible to work on documents together.Web Conferencing - Video Conferencing solely conducted on the Internet
- 39. COLLABORATION TOOLSGROUPWAREReal-Time CollaborationHelp companies bridge time and space to make decisions and to collaborate on projectsSynchronous communication of graphical and text-based information. Examples:Interactive Whiteboards- work like the “physical world” whiteboards with markers and erasers, except instead of one person standing in front of a meeting room drawing on the whiteboard, all participants can join in (Dabbleboard)Screen Sharing Software - allows group members to work on the same document, which is shown on the PC screen of each participant.Instant Video - is a kind of real time chat room that allows you to see the person you are communicating with (Skype)
- 40. WEB BASED APPLICATIONSDistance Learning (DL)For situations where teachers and students do not meet face-to-faceE-Learning is just one of the methodsAdd value to traditional learning modes. It does not replace the classroom setting, but enhances it, taking advantage of new content and delivery technologiesBlackboard Inc – provides and e-education infrastructure (e.g. Learnfinity)
- 41. WEB BASED APPLICATIONSTelecommuting / TeleworkingAn arrangement whereby employees can work at home, at the customer’s premises, in special work places, or while traveling, usually using a computer linked to their place of employment (e.g. remote desktops / connections)Benefits:Improved productivityReduced costs (e.g. traveling)Disadvantages:To the employees – isolation, no workplace visibility, limited socializationTo the employers – difficult to supervise, data security, high cost of integration
