What does a Repeater do?
Repeaters receive an electronic signal and amplify it to increase the physical range of the transmission range.
What does a Network Interface Card? (NIC)
Network interface cards convert data between the computer (commonly the PCI bus) into a form suitable for transmission across the network.
What does a Hub do?

What are ADSL modems?
ADSL modems are modems which function by Asymmetrical Digital Subscriber Lines who use existing copper telephone lines to transfer broadband signals.
What are Cable Modems?
Modems function by cables to connect to the Internet through coaxial cables.
What do Routers do?
Routers direct messages over the most efficient path to their destination.
