Baud rate: A measurement of how many bits could be passed across a phone line in a second
Bluetooth: The most common short range wireless network
Broadband: Any connectivity technology that isn't dial-up Internet
Cable modem: A device that sits at the edge of a consumer's network and
connects it to the cable modem termination system
Cable modem termination system: Connects lots of different cable connections
to an ISP's core network
Channels:Individual, smaller sections of the overall frequency band used by a wireless network
Collision domain: A network segment where only one device can communicate at a time
Data payload section: Has all of the data of the protocols further up the stack of a frame
Dial-up: Uses POTS for data transfer, and gets its name because the connection is established by actually dialing a phone number
DSL: Digital subscriber line was able to send much more data across the wire than traditional dial-up technologies by operating at a frequency range that didn't interfere with normal phone calls
DSLAM:Digital Subscriber Line Access Multiplexers are devices that connect multiple DSL connections to a high-speed digital communications channel
Duration field: Specifies how long the total frame is
Frame check sequence: It is a 4-byte or 32-bit number that represents a checksum value for the entire frame
Frame control field: 16 bits long, it contains a number of sub-fields that are used to
describe how the frame itself should be processed
Frequency band:A certain section of the radio spectrum that's been agreed upon to be used for certain communications
FTTB: Fiber to the building, fiber to the business or even fiber to the basement, since this is generally where cables to buildings physically enter. FTTB is a setup where fiber technologies are used for data delivery to an individual building
