2. Networked Devices Networked devices are devices that communicate with a network. Technologies include laptops, PDAs, cell and smar tphones, wikis, intranets, and extranets, GPSs, PO S terminals, and RFID which allow information to b e rapidly collected, processed, shared, and acted upon for competitive survival and advantage takin g. Feature-rich wireless devices make collaboration e asier and more productive which indicates a more integrated, always-connected business environme nt and lifestyle.

5. Social Networking Shrinks the World Social networking via mobile phones is shrinking t he world to the size of a small screen. Micro-blogging is the sending of messages up to 1 40 characters. With more than 3 billion mobile handsets in use in the world (1 for every 2 people on the planet) a po werful force for changes in business and collabora tion as well as politics and societies have emerged. News media, universities, public safety, and other organizations are using the technology to deliver i nformation to a wide audience quickly.

6. 4.1 Business Networks Business networks support 4 basic functions: 1.mobility 2.collaboration 3.relationships 4.Search

7. Network basics Figure 4.2 A signal is transmitted from a sender/source to a re ceiver/destination via circuit or packet switching.

8. Network Terminology Bandwidth: Throughput capacity or speed of a network. Protocol: Standards that govern how networked devices e xchange information. TCP/IP: Transmission control protocol/Internet Protocol) ar e a suite of Internet protocols. Broadband: Short for broad bandwidth. –Fixed-line broadband: Cable or DSL Internet connections. –Mobile broadband: Wireless high-speed Internet access through a portable modem, phone, or other device.

9. 4.2 Wireless Broadband Networks Enterprises are moving away from unsystematic ad option of mobile devices and infrastructure to a strate gic build-out of mobile capabilities. Mobile infrastructure consists of technology, soft ware, support, security measures, and devices to m anage and deliver wireless communications.

10. 4.3 Networks Management and Por tals When the network goes down or access is blocked, so d oes the ability to operate or function. Damages when a company cannot operate or fulfill orders inc lude: –lost sales and productivity –Inability to send and receive payments –inability to process payroll and inventory

11. TCP/IP Networks The Internet protocol suite consists of the IP (Internet Pr otocol) and TCP (Transport Control Protocol), or TCP/IP. In preparation for transmission, data are digitized into pa ckets and sent via packet-switched networks, local area networks (LAN), or wide area networks (WAN).

12. Discovery Discovery allows users to browse and sear ch data sources, in all topic areas, on the Web. –Search engines –Metasearch engines –Discovery of material in foreign languages

13. Four Largest Search Engines Google Yahoo Microsoft Network Ask

14. Metasearch Engines Surf-Wax Metacrawler Mamma

15. Publication of Material in Foreign La nguages Translation products include: –Altavista –Google –Trados

16. Network Computing Infrastructures Intranets: a network serving the internal infor mational needs of a company. Extranets: private, company-owned network that uses I P technology to securely share part of a business’s inf ormation or operations with suppliers, vendors, partne rs, customers, or other businesses. Extranets can use virtual private networks (VPNs). VPNs are created using specialized software and hardware to encrypt/send/decrypt transmissions over the Intern et.

21. Telepresence Systems

22. Leading Telepresence Systems Cisco Telepresence 3000

23. Collaboration Support Technologies Portals, intranets, extranets, and shared workspace s are examples. Web 2.0 or Enterprise 2.0 technologies such as wiki s, blogs and microblogs, provide more options to pr omote and support enterprise collaboration.

24. Minicase : Wikis, Blogs, and Chats Support Collaboration at DrKW WikisWikis used in business continue to grow.

25. Wild About Wikis By Rachael King Intel, Motorola, Sony—they're among the companies using Web-collaboration tools to promote products and foster teamwork among employees

26. Wikis are Web-based tools that make it easy for users to add, remove, and change online content. Employees at companies such as Intel, Motorola, IBM, and Sony use them for a host of tasks, from setting internal meeting agendas to posting documents related to new products.

27. Many companies rely on wikis to engage customers in ongoing discussions about products. Wikis for Motorola and T-Mobile handsets serve as continually updated user guides. TV networks including ABC and CBS are creating fan wikis that let viewers interact with each other as they unravel mysteries from such shows as Lost and CSI: Crime Scene Investigation. Read about these and other ways companies are warming to wikis. A link is included where the wiki is open to the public.
