Chapter 6 Answers to Discussion Questions:1.The TCP/IP provides a universally agreed-on method for breaking up digital messages into packets,routing them to the proper addresses,and then reassembling them into coherent messages.Businesses using the TCP/IP standard can use a wide variety of hardware and software that is readily available thus sidestepping the need to create proprietary software and special hardware.Because of the universal acceptance of the TCP/IP,standard businesses can build networks that anyone anywhere can use.2.A few of the Internet services available to businesses include e-mail,electronic discussion groups,chatting,instant messaging,Telnet,FTP,and of course the World Wide Web.All of these services provide a universal method of connecting employees,customers,suppliers,and business partners in an inexpensive way.3.Internet Telephony enables companies to use Internet technology for telephone voice transmission over the Internet or private networks.Voice over IP(VoIP)technology uses the Internet Protocol(IP)to deliver voice information in digital form using packet switching,avoiding the tolls charged by local and long-distance telephone networks.IP telephony calls can be made and received with a desktop computer equipped with a microphone and speakers or with a VoIP-enabled telephone.4.Answers will vary but should include information abut the benefits of linking functional areas of an organization to increase communication between co-workers and teams,making information more accessible to employees and suppliers,and reducing costs associated with disseminating information.Answers should address how to integrate wireless technology into the rest of the firms IT infrastructure,how to maintain security and privacy,and how the relationships between employees,customers,suppliers,and business partners will change.5.RFID tags provide wireless transmission of more data in a real-time mode than does bar code technology.The RFID tags can trigger other processes with an information system based on the data contained in the tag.Because RFID tags do not require line-of-sight readers,data transmissions are faster and easier.
