Living in a network centric world

Living in a Network Centric WorldNetwork Fundamentals – Chapter 1ObjectivesDescribe how networks impact our daily lives.Describe the role of data networking in the human network.Identify the key components of any data network.Identify the opportunities and challenges posed by converged networks.Describe the characteristics of network architectures: fault tolerance, scalability, quality of service and security.Install and use IRC clients and a Wiki server.How Networks Impact Daily LifeExplain the benefits of instantaneous communication and how it supports and improves our livesHow Networks Impact Daily LifeDescribe the characteristics and purpose of popular communication media such as, IM, Wikis , Blogs, Podcasting, and Collaboration ToolsInstant messagingReal time communication between 2 or more people based on typed textWeblogs (Blogs)Web pages created by an individualPodcastingWebsite that contains audio files available for downloadingHow Networks Impact Daily LifeExplain ways that using information networks to share and collaborate improves teaching and learningHow Networks Impact Daily LifeDescribe ways communication over a network changes the way we workHow Networks Impact Daily LifeDescribe ways communication over a network supports the way we playData Networking Role, Components, and ChallengesBasic characteristics of communicationRules or agreements are 1st establishedImportant information may need to be repeatedVarious modes of communication may impact the effectiveness of getting the message acrossData Networking Role, Components, and ChallengesDescribe the role of data networking in communicationsData Networking Role, Components, and ChallengesDescribe the various elements that make up a networkDevicesThese are used to communicate with one anotherMediumThis is how the devices are connected togetherMessagesInformation that travels over the mediumRulesGoverns how messages flow across networkData Networking Role, Components, and ChallengesDescribe the role of converged networks in communicationsConverged networkA type of network that can carry voice, video & data over the same networkNetwork Architecture CharacteristicsExplain four characteristics that are addressed by network architecture designFault toleranceScalabilityQuality of serviceSecurityNetwork Architecture CharacteristicsDescribe how packet switching helps improve the resiliency and fault tolerance of the Internet architectureNetwork Architecture CharacteristicsDescribe characteristics of the Internet that help it scale to meet user demandHierarchicalCommon standardsCommon protocolsNetwork Architecture CharacteristicsExplain the factors that necessitate Quality of Service and the mechanisms necessary to ensure itNetwork Architecture CharacteristicsDescribe how QoS mechanisms work to ensure quality of service for applications that require itNetwork Architecture CharacteristicsDescribe how to select the appropriate QoS strategy for a given type of trafficNetwork Architecture CharacteristicsDescribe why networks must be secureNetwork Architecture CharacteristicsDescribe basic measures to secure data networksEnsure confidentiality through use ofUser authenticationData encryptionMaintain communication integrity through use ofDigital signaturesEnsure availability through use ofFirewallsRedundant network architectureHardware without a single point of failureIRC Clients and Wiki ServerInstall and use IRC clients and a Wiki serverSummary
