  1. Connecting to the Network Introduction to Networking Concepts

  2. Part 1 - Objectives • Explain the concept of networking and the benefits of networks. • Explain the concept of communication protocols. • Explain how communication occurs across a local Ethernet network. • Describe Access layer devices and communication methods on a local Ethernet network. • Describe Distribution layer devices and communication methods across networks. • Explain different types of cabling used to physically connect devices on the network. • Plan, implement, and verify a local network.

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

  4. Network Structure • Define the components of a network • Network components • Hardware • Software

  5. Networking and Its Benefits • Define the components of an Information network

  6. Networking and Its Benefits • Describe the Roles of computers on a network • Clients and servers

  7. Networking and Its Benefits • Build computer peer-to-peer network and verify

  8. Network Types • Define Local Area Networks (LANs) • A network serving a home, building or campus is considered a Local Area Network (LAN)

  9. Network Types • Define Wide Area Networks (WANs) • LANs separated by geographic distance are connected by a network known as a Wide Area Network (WAN)

  10. Network Topologies • Differentiate between logical and physical topologies, and explain how networks are represented graphically

  11. Communication Protocols • Explain the concept of communication in terms of source, destination and channel

  12. Communication Protocols • Explain the need for rules and protocols in order for communication to occur

  13. Communication Across a Local Ethernet Network • Explain that Devices on a local network must share common protocols to communicate (Communicating by the Rules)

  14. Communication Across a Local Ethernet Network • Physical addressing identifies Source, Destination and Channel on an Ethernet Network

  15. Communication Across a Local Ethernet Network • Describe some of the basic characteristics of Ethernet for communicating across the channel

  16. Communication Across a Local Ethernet Network • Explain the purpose of a logical network address as the location of a host on a Network (source and destination)

  17. Access Layer Devices and Communication Methods • Describe the Purpose of the Access Layer and how it is used within an Ethernet Network

  18. Methods of Obtaining an IP Address • Describe the methods of assigning an IP Address • Static Assignment • Dynamic Assignment

  19. Access Layer Devices and Communication Methods • Describe the function of a Hub and how it operates within an Ethernet Network

  20. Access Layer Devices and Communication Methods • Describe the function of switches and how they are used in an Ethernet network

  21. Access Layer Devices and Communication Methods • Broadcast Domains and broadcasts using hubs and switches

  22. Distribution Layer Devices and Communication Methods • Describe the reasons for expanding your network with a distribution layer

  23. Distribution Layer Devices and Communication Methods • Describe the function of routers and how they are used in the network

  24. Distribution Layer Devices and Communication Methods • Explain the concept of the default gateway

  25. Distribution Layer Devices and Communication Methods • Describe how the router keeps tract of multiple networks using routing and ARP tables

  26. Distribution Layer Devices and Communication Methods • Define the term “local area network (LAN)”

  27. Distribution Layer Devices and Communication Methods • Differentiate between implications of adding hosts to “My local network” vs. adding to a “remote network”

  28. Distribution Layer Devices and Communication Methods • Learn to Use Packet Tracer

  29. Types of Cables and Connectors Used in Networking • Identify and describe common types of cables

  30. Types of Cables and Connectors Used in Networking • Describe twisted pair cables, common terminations, and when they are used

  31. Types of Cables and Connectors Used in Networking • Describe Coax cable, common terminations, and when they are used

  32. Types of Cables and Connectors Used in Networking • Describe optical fiber cables, common terminations, and when they are used

  33. Construct and Terminate Twisted Pair Cables • Define cable standards and state their purpose

  34. Construct and Terminate Twisted Pair Cables • Identify and describe the cross-over and straight through cable pinouts and color codes

  35. Construct and Terminate Twisted Pair Cables • Describe how to terminate UTP cables

  36. Construct and Terminate Twisted Pair Cables • Describe how to punch down wires to patch panel and wall jacks.

  37. Construct and Terminate Twisted Pair Cables • Describe how to test cable termination and functionality (Cable testing).

  38. Plan, Implement and Verify a Local Network • Plan and document the building of a small home or small business Ethernet network

  39. Plan, Implement and Verify a Local Network • Build a virtual model of their small home or small business network

  40. Plan, Implement and Verify a Local Network • Describe the features of multifunction devices and how they are used in the network

  41. Plan, Implement and Verify a Local Network • Connect and properly document the network installation

  42. Plan, Implement and Verify a Local Network • Perform simple workgroup tasks in order to share resources

  43. Summary • Information networks carry data using hosts as clients, servers, or both. • All computer communication involves a source, destination, and channel. • Rules called protocols govern computer communications. • Larger networks are divided into smaller, more manageable ones using a layered hierarchical design. • Each network host needs both a physical MAC address and a logical IP address. • Good network design requires a network plan.

  44. Part 2 - Objectives • Explain “what is the Internet?” and how we connect to the Internet using an Internet Service Provider (ISP). • Compare TCP and UDP. • Explain the functions of DNS and DHCP. • Compare and contrast clients and servers and their interaction over the network. • Describe the type of interactions of Internet applications. • Describe the purpose of a layered model • Illustrate the interaction of various protocols.

  45. The Internet and How We Connect to It Using an ISP • Define an Internet Service Provider and its purpose

  46. What is the Internet? • An ISP is a company or organization through which a subscriber obtains Internet access.

  47. The Internet and How We Connect to It Using an ISP • Identify and describe the different connection options that ISPs can provide

  48. How Information is Sent When Using an ISP • Describe how the ISP forwards packets across the Internet

  49. The Internet Cloud • Identify and describe the concept of the Internet cloud.

  50. Protocols That Support ISP Services • The TCP/IP suite of protocols supports reliability
