  5. Living in a Network Centric World In the present

  6. How Networks Impact Daily Life • Explain the benefits of instantaneous communication and how it supports and improves our lives

  7. How Networks Impact Daily Life • Describe the characteristics and purpose of popular communication media such as, IM, Wikis , Blogs, Podcasting, and Collaboration Tools • Instant messaging • Real time communication • between 2 or more • people based on typed text • Weblogs (Blogs) • Web pages created • by an individual • Podcasting • Website that contains • audio files available • for downloading

  8. How Networks Impact Daily Life • Explain ways that using information networks to share and collaborate improves teaching and learning

  9. How Networks Impact Daily Life • Describe ways communication over a network changes the way we work

  10. How Networks Impact Daily Life • Describe ways communication over a network supports the way we play

  11. Data Networking Role, Components, and Challenges • Basic characteristics of communication • Rules or agreements are 1st established • Important information may need to be repeated • Various modes of communication may impact the effectiveness of getting the message across

  12. Data Networking Role, Components, and Challenges • Describe the role of data networking in communications

  13. Data Networking Role, Components, and Challenges • Describe the various elements that make up a network • Devices • These are used to communicate with one another • Medium • This is how the devices are connected together • Messages • Information that travels over the medium • Rules • Governs how messages flow across network

  14. Data Networking Role, Components, and Challenges • Describe the role of converged networks in communications • Converged network • A type of network that can carry voice, video & data over the same network

  15. Network Architecture Characteristics • Explain four characteristics that are addressed by network architecture design • Fault tolerance • Scalability • Quality of service • Security

  16. Network Architecture Characteristics • Describe how packet switching helps improve the resiliency and fault tolerance of the Internet architecture

  17. Network Architecture Characteristics • Describe characteristics of the Internet that help it scale to meet user demand • Hierarchical • Common standards • Common protocols

  18. Network Architecture Characteristics • Explain the factors that necessitate Quality of Service and the mechanisms necessary to ensure it

  19. Network Architecture Characteristics • Describe how QoS (Quaity of Service) mechanisms work to ensure quality of service for applications that require it

  20. Network Architecture Characteristics • Describe how to select the appropriate QoS strategy for a given type of traffic

  21. Network Architecture Characteristics • Describe why networks must be secure

  22. Network Architecture Characteristics • Describe basic measures to secure data networks • Ensure confidentiality through use of • User authentication • Data encryption • Maintain communication integrity through use of • Digital signatures • Ensure availability through use of • Firewalls • Redundant network • architecture • Hardware without a single • point of failure

  23. Explain How a Hierarchical Network Design Creates a Stable, Reliable, Scalable Network Network requirements: • Ease of management • Fast recovery • Application response time • Fast troubleshooting

  24. Explain How a Hierarchical Network Design Creates a Stable, Reliable, Scalable Network Four fundamental network design goals: • Scalability • Availability • Security • Manageability

  25. Explain How a Hierarchical Network Design Creates a Stable, Reliable, Scalable Network • Core Layer: connects Distribution Layer devices • Distribution Layer: interconnects smaller LANs • Access Layer: provides connections for hosts and end devices

  26. Explain How a Hierarchical Network Design Creates a Stable, Reliable, Scalable Network Subdividing the three-layer model into modular areas: • Enterprise campus • Server farm • Enterprise edge

  27. Explain How a Hierarchical Network Design Creates a Stable, Reliable, Scalable Network Steps in network design projects: • Identify the network requirements • Characterize the existing network • Design the network topology and solutions

  28. Utilize the Hierarchical Design Model to Develop a Cost-Effective Network Design • Create the logical LAN diagram, including the locations of servers and services

  29. Cisco Packet Tracer
