Create a Multi-Computer Wired Home Network

Understand Home Network Design

[ Theory and Background | Vocabulary | Teacher Notes | Extra Resources | Video Script ] (Jstraw)

Outline

1. What is the internet?
2. Metaphor for the internet:
   • House - (address vs. physical description)
   • Local Streets / Neighborhood - LAN
   • State, City/County - ISP, local division of ISP
   • Country - Internet
   • Major Roads (US routes / Bigger State Routes) - Internet Connectivity
   • Highways - Internet Backbones
   • Post Office - Router (GET Picture of 495/395/95)
   • Intersection - Hub
   • Highway Intersection (Mixing Bowl) - Switch
   • (create video piece)
3. What is a home network?
   • LAN vs. WAN
4. The OSI model and why it's important
   • You have blueprint for your house;
   • This is a blueprint for a network
   • Talk about Layers 1 2 3 4 and 7 (7 as 567 combined)

Worksheets

1. Identify internet terms and definitions [ BlueprintWorksheetIdentify ]
2. Quiz: Identify internet terms and definitions [ BlueprintWorksheetQuiz ]

Hands-On Activities

Using the roadmap metaphor for the internet, make your own internet roadmap. Please include the following internet features:

• hub, switch, router
• LAN cabling, WAN cabling
• ISP, LAN, WAN

Understand Network Addressing

[ Theory and Background | Vocabulary | Teacher Notes | Extra Resources | Video Script ] (Gina)

Outline

1. How does someone get to your house?
   • Country (internet)
   • State and City/County (ISP)
   • Street Name / Number (IP Address, given by someone)
   • Physical Description of house (MAC Address, set by manufacturer/builder)
2. Types of Addresses
   • IP address
     • IPv4 address, 32-bits of binary (4 sets of eight)
       • IPv6 coming soon: scheme will greatly expand in scope with IPv6
     • Assigned by ISP
     • IP addresses you should know about:
       • 192.168.0.0/16 and 172.16.0.0/12 10.0.0.0/8
   • MAC addresses
     • 48-bits of binary in 12 hex digits (6 sets of two)

Worksheets

1. Identify some different IPv4, IPv6, and MAC addresses [ AddressingWorksheetIdentify ]

Hands-On Activities

1. Find the MAC and IP address of your computer. [ AddressingLabFind ]

Understand Bandwidth Types and Speeds

[ Theory and Background | Vocabulary | Teacher Notes | Extra Resources | Video Script ] (Charles)

Outline

1. Bits and bytes defined
2. What is bandwidth?
   • Uplink vs Downlink speeds
3. Types of bandwidth:
   • dial-up
   • dsl
   • cable
   • fiber
4. Speed vs storage units
5. Bandwidth bit-sizes: kilo, mega, giga, tera, peta, exo

Worksheets

1. Research the different prices of internet connectivity of dial-up,dsl,cable and fiber

Hands-On Activities

1. Configure a modem and dialer [ BandwidthLabModem ]
2. Connect a computer to a cable or dsl modem using ethernet cable [ BandwidthLabDSL ]

Cable the Home Network

[ Theory and Background | Vocabulary | Teacher Notes | Extra Resources | Video Script ] (Robert)

Outline

1. cat 5e (solid, stranded and plenum)
2. cat 6
3. Wiring Standards
   • EIA/TIA-568-A
   • EIA/TIA-568-B
4. Types of Ethernet Cable
   1. Straight-through/Standard
      • Computer to Network Device (Hub, Switch, Router)
      • A <-> A
      • B <-> B
   2. Crossover
      • Network Device to Network Device
      • Computer to Computer
      • A <-> B
   3. Rollover
      • Console Cable for certain Network Devices
      • A <-> Upside down A (flip the RJ45 jack over before inserting)
      • B <-> Upside down B (flip the RJ45 jack over before inserting)

Worksheets

Hands-On Activities

1. LAB: crimp cat5 cable with rj-45 connectors[ CrimpingLab ]
2. LAB: Punchdown cat5 cable to wall mount

Connect Wired Devices

[ Theory and Background | Vocabulary | Teacher Notes | Extra Resources | Video Script ] (Ray)

Outline

1. Switches and Hubs
   • Hubs work at layer 1 (like a power strip)
   • Switches work at layer 2
     • Switches are smart, they choose the correct cable to send data to
     • Better Switches (Multilayer switches) are even programmable and allow you to add security

Worksheet

Hands-On Activities

1. LAB: connect 2 computers with a crossover cable [ CrossoverLabCable ]
2. LAB: connect 2 computers with a switch [ SwitchLabconnection ]

Connect to Bandwidth

[ Theory and Background | Vocabulary | Teacher Notes | Extra Resources | Video Script ] (Rodrigo)

Outline

1. You will need a layer 3 device, called a personal router
2. Router functions:
   • Makes decisions on where to send traffic
   • Security via Firewall
   • Segments Network (defines Neighborhood)
3. Uses IP
4. Where do the addresses come from?
   • They're dealt like cards from a server
     • Server: Dynamic Host Configuration Protocol
   • Or they're permanently assigned to your computer.
     • Static Addressing
   • DSL/Cable Gotchas
     • ISP assigns 1 IP address
     • Router use this one address to serve an entire LAN
       • Network Address Translation

Worksheets
