| what are Ethernet cards | the standard network adapters used on most desktop computers |
| what is a wireless network | a network which uses over-the-air signal for connections and does not require any weird connections |
| what is a bandwidth | the amount of data you can push through a network connection over a given time |
| what is a coaxial | the first type of cable used for networking, consisting of a solid copper wire surrounded by insulation |
| what is a twisted pair wire | cables containing up to 8 wires, would together in pairs to minimize electromagnetic interference, used for Ethernet cables |
| what is a baseband cable | a cable where bi-directional data is sent using digital signal that take up the entire bandwidth (or capability) of the cable |
| what is a broadband cable | a cable where uni-directional data is sent in the form of an analog signal. more than one stream of data can be sent over the cable at one time |
| what is a hub | a central device that contains any different ports (sockets) |
| what is a switch | a smarter version of a hub, which is capable of sending information to a single recipient in a network |
