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Hubs are outdated with speeds limited to 10 Mbps and 100 Mbps.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.
