    • 7.2: Explain different methods of classifying networks.
    • 7.3: Describe wireless and wired transmission media used in networks.
    • 7.4: Describe essential hardware components necessary for networks (ex. network adapters, modems, routers, switches).
    • 7.5: Outline the types of software needed for computer networks.
    • 7.6: Summarize broadband options available for accessing the internet.
    • 7.7: Explain wireless Internet access methods.
    • 7.8: Considerations for creating a home network (devices, standards, equipment).
    • 7.9: Describe the setup of a home network, including routers and switches.
    • 7.10: Troubleshoot wireless network problems (e.g., signal range, interference).
    • 7.11: Methods for securing wireless home networks (encryption, passwords, etc.).
    • 7.12: Configuring security settings on a router (SSID, security protocols).

    Networking Fundamentals

    • Computer network: A system of two or more computers connected to share information and resources.
    • Node: Each device (computer, peripheral, or network device) connected to a network.
    • Benefits: Sharing high-speed internet, printers, files, and facilitating communications.
    • Disadvantages: Network setup and administration.
    • Data transfer rate (bandwidth): Maximum data transmission speed.
    • Throughput: Actual data transfer speed.
    • Units: Measured in megabits per second (Mbps) and gigabits per second (Gbps).

    Network Architectures

    • Networks can be categorized by distance (e.g., PAN, LAN, HAN, MAN, WAN).

    • Personal area network (PAN): Short-range connections for devices around one person.

    • Local area network (LAN): Network in a small geographical area (e.g., home, office).

    • Home area network (HAN): A specific type of LAN found within a home.

    • Metropolitan area network (MAN): Network connecting multiple devices within a city.

    • Wide area network (WAN): Networks covering large geographical areas (e.g., countries).

    • Client/server network: A network where a central server handles requests from client computers.

    • Peer-to-peer (P2P) network: Network where each device can communicate directly with any other device.

    Network Components

    • Protocols (e.g., Ethernet, Wi-Fi): Standards that define how data travels through networks.

    • Ethernet: Common wired standard

    • Wi-Fi: Wireless standard for networks.

    • Transmission media: Method for connecting devices (wired/wireless). This includes UTP, coaxial and fiber optics cables.

    • Hardware: Network devices like network interface cards (NICs), modems, routers, switches.

      • NIC: Network interface card; allows devices to communicate on a network.
      • Modem: Converts digital signals to analog signals and back to allow communication over phone lines.
      • Router: Transfers data packets between different networks.
      • Switch: Acts like a traffic controller for data packets on a network.
    • Software: Network operating system (NOS) software manages network operations and resources. This is important for home networks(P2P) and client-server networks.

    Connecting to the Internet

    • Broadband: High-speed internet access (e.g., cable, DSL, fiber optic).
      • Cable Internet: Uses coaxial cables.
      • DSL: Uses existing telephone lines.
      • Fiber optic: Uses light pulses.
    • Cellular/dial-up: Alternative internet options if broadband isn't available.

    Installing and Configuring Home Networks

    • Necessary stepsinclude devices, the latest standards and equipment.
    • Types of devices for a home network include routers and switches.
    • Specialized networking devices are network-attached storage (NAS) devices and home network servers.

    Troubleshooting and Securing Wireless Networks

    • Troubleshooting: Identify common problems like weak signals, interference.

    • Troubleshooting strategies: Use a wireless range extender, and select an optimal access point.

    • Security: Methods for securing a wireless network (encryption through security protocol, changing network name; disabling SSID broadcast, changing default password and creating a passphrase ). Network security involves several factors like, limiting radio waves, employing media access control, and keeping router firmware up-to-date.
