1 Chapter Nine Networking and Telecommunication
2 After reading this chapter, you should be able to: Describe the nature and function of local area networks and wide area networks Discuss the uses and implications of electronic mail, teleconferencing, and other forms of on-line communication Describe several types of communication services that are available with or without an Internet connection 1999 Addison Wesley Longman 9.2
3 After reading this chapter, you should be able to: Describe several types of electronic digital communication that don t necessarily involve personal computers Describe current and future trends in telecommunications and networking 1999 Addison Wesley Longman 9.3
4 Chapter Outline Linking Up: Network Basics Electronic Mail and Teleconferencing: Interpersonal Computing The Other Side of the Modem: An On-line Tour Telecommunication Trends: Merging and Emerging Technologies 1999 Addison Wesley Longman 9.4
5 Linking Up: Network Basics Basic Network Anatomy Networks Near and Far Communication Software The Network Advantage 1999 Addison Wesley Longman 9.5
6 Basic Network Anatomy A computer network is any computer system that links two or more computers There are three essential components in a network: Hardware Software People 1999 Addison Wesley Longman 9.6
7 The Network Interface A network interface card (NIC): Is needed to connect directly to a network Adds an additional port to the computer Controls the flow of data between the computer s RAM and the network cable Converts the computer s digital signals into the type required for the particular network 1999 Addison Wesley Longman 9.7
8 Communication á la Modem A modem is needed to connect a computer to a phone line The computer communicates with digital signals The telephone system was designed to transmit voice signals which are analog 1999 Addison Wesley Longman 9.8
9 Communication á la Modem A modem: Converts the digital stream of information from a computer to an analog stream in order to send a message on the telephone network 1999 Addison Wesley Longman 9.9
10 Communication á la Modem A modem: Converts the analog stream of information received over the telephone network into the digital form that the computer understands 1999 Addison Wesley Longman 9.10
11 How a Modem Works The word modem comes from the terms modulation and demodulation Modulation Digital signals Analog signals Phone line Demodulation Digital signals Modem Terminal Modem Computer 1999 Addison Wesley Longman 9.11
12 Networks Near and Far There are two general types of computer networks: LAN (Local Area Network) WAN (Wide Area Network) 1999 Addison Wesley Longman 9.12
13 LAN (Local Area Network) A LAN is a network in which the computers are physically close to each other LAN networks are usually set up to share peripherals, such as printers and network servers Each computer and shared peripheral is a node on the LAN 1999 Addison Wesley Longman 9.13
14 WAN (Wide Area Network) A WAN is a network in which the computers are a great distance from one another Connections are made via telephone lines, satellites, and/or microwave relay towers Each network site is a node 1999 Addison Wesley Longman 9.14
15 WAN (Wide Area Network) WANs are often made up of LANs 1999 Addison Wesley Longman 9.15
16 Communication Software Communication software includes: Software that allows the hardware to interact with various networks A network operating system (NOS) which controls information shared between the dedicated server and client machines ACME Network Operating System 1999 Addison Wesley Longman 9.16
17 Client/Server Model 1999 Addison Wesley Longman 9.17
18 Peer-to-Peer Model The peer-to-peer model allow every computer on the network to be both client and server Peer-to-peer networking is built into some operating systems Many networks use a hybrid of client/server and peer-to-peer 1999 Addison Wesley Longman 9.18
19 The Network Advantage Networks allow people to: Share computer resources (hardware and software) Share data Work together in new ways 1999 Addison Wesley Longman 9.19
20 Electronic Mail and Teleconferencing: Interpersonal Computing Electronic mail and teleconferencing allow communication between two or more computer users People can communicate in real time or delayed time, this has both advantages and disadvantages 1999 Addison Wesley Longman 9.20
21 Real-time vs. Delayed Communication Real-time communication (synchronous): participants meet in real time participants see each other s typed messages as they are typed examples: Talk and Chat 1999 Addison Wesley Longman 9.21
22 Real-time vs. Delayed Communication Delayed communication (asynchronous): Participants type, post, and read messages at their convenience Participants share an electronic mailbox among a group Examples: and Newsgroups 1999 Addison Wesley Longman 9.22
23 Fast Advantages of and Teleconferencing Doesn t depend on location or time Facilitate group communication Messages can be edited and combined with other computergenerated documents 1999 Addison Wesley Longman 9.23
24 Advantages of and Teleconferencing Allow decisions to evolve over time Make long-distance meetings possible Emphasize the message, not the messenger 1999 Addison Wesley Longman 9.24
25 Disadvantages of and Teleconferencing Vulnerable to machine errors, human errors, and security breaches Can pose a threat to privacy Can be faked Please Standby 1999 Addison Wesley Longman 9.25
26 Disadvantages of and Teleconferencing Work only if the recipient responds Can be overwhelming Both filter out many human components of communication 1999 Addison Wesley Longman 9.26
27 The Other Side of the Modem: An On-line Tour Popular services available using a modem include: Bulletin Boards On-line Databases Commercial On-line Services 1999 Addison Wesley Longman 9.27
28 Bulletin Board Systems A BBS is an on-line version of a bulletin board where people post messages to others BBSs are divided into groups of people with a common interest (SIG special interest group) Most BBSs allow members to post messages and download or upload software 1999 Addison Wesley Longman 9.28
29 On-line Databases Electronic databases allow users to connect (usually for a fee) to a variety of on-line databases On-line databases include: current stock market status legal briefs library resources medical references 1999 Addison Wesley Longman 9.29
30 Commercial On-line Services Commercial services include generalpurpose on-line information services such as America Online, CompuServe, MSN, and Prodigy The Internet is forcing on-line services to change the way they do business 1999 Addison Wesley Longman 9.30
31 Commercial On-line Services Members pay a fee for these services: News Research Shopping Banking Games BBS teleconferences 1999 Addison Wesley Longman 9.31
32 Rules of Thumb: On-line Survival Tips If you don t have to be on-line, go offline Avoid peak hours Let the system simplify and streamline your work Store names and addresses in an on-line address book 1999 Addison Wesley Longman 9.32
33 Rules of Thumb: On-line Survival Tips Protect your privacy Cross-check on-line information sources Be aware of the amount of time you spend on-line Avoid information overload 1999 Addison Wesley Longman 9.33
34 Telecommunication Trends: Merging and Emerging Technologies Alternative Technologies: Facsimile transmission Voice mail and computer telephony Video teleconferencing E-money Personal digital assistants 1999 Addison Wesley Longman 9.34
35 Telecommunication Trends: Merging and Emerging Technologies Meeting the demands of tomorrow's network applications through Digital Phone Connections: DDS (digital data service) T1 ISDN (integrated services digital network) ADSL (asymmetric digital subscriber) Cable modems 1999 Addison Wesley Longman 9.35
36 Telecommunication Trends: Merging and Emerging Technologies Optical Networks: Fiber optic cables are replacing copper wires Light waves are used to carry information Provide data rates over one billion bits per second Offer extremely low error rates 1999 Addison Wesley Longman 9.36
