    Study Notes

    • Hubs were once commonly used to connect devices on a network, acting as multi-port repeaters.
    • Hubs re-transmit data to all interfaces, which is inefficient and limits communication to half duplex.
    • Hubs are outdated with speeds limited to 10 Mbps and 100 Mbps.
    • Cable modems are used for broadband communication over cable networks and support DOCSIS standard.
    • DSL modems provide Internet connectivity over telephone lines, with speeds varying depending on distance from Central Office and provider.
    • Fiber connections are used for high-speed internet and require an Optical Network Terminal (ONT) to connect to the ISP's network.
    • Network Interface Cards (NICs) are used to connect devices to various types of networks, including copper, fiber, serial, and wireless.
    • Hubs are not efficient for networking due to the re-transmission of data to all interfaces.
    • Cable modems support high-speed internet and can provide other services such as cable television and phone lines.
    • DSL modems provide internet connectivity using telephone lines and have limitations in terms of distance and speed.
    • Fiber connections offer high-speed internet and require an ONT to convert the fiber signal to a form usable inside a building.
    • NICs are used to connect devices to various types of networks and come in different forms such as cards, built-in interfaces, and adapters.
