Connecting to the Internet Flashcards
A network configuration without supporting network infrastructure. Every device involved with the ad-hoc network communicates with every other device within range, and all nodes help pass along messages
AD-HOC NETWORK
A device that establishes data connections across phone lines and different speeds for uploading and downloading data
ASYMMETRIC DIGITAL SUBSCRIBER LINE (ADSL)
A measurement of how many bits could be passed across a phone line in a second
BAUD RATE
The most common short range wireless network
BLUETOOTH
Any connectivity technology that isn’t dial-up Internet
BROADBAND
A device that sits at the edge of a consumer’s network and connects it to the cable modem termination system
CABLE MODEM
Connects lots of different cable connections to an ISP’s core network
CABLE MODEM TERMINATION SYSTEM
Individual, smaller sections of the overall frequency band used by a wireless network
CHANNELS
A network segment where only one device can communicate at a time
COLLISION DOMAIN
Has all of the data of the protocols further up the stack of a frame
DATA PAYLOAD SECTION
Uses POTS for data transfer, and gets its name because the connection is established by actually dialing a phone number
DIAL-UP
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
DSL (DIGITAL SUBSCRIBER LINE)
Devices that connect multiple DSL connections to a high-speed digital communications channel
DSLAM (DIGITAL SUBSCRIBER LINE ACCESS MULTIPLEXERS)
Specifies how long the total frame is
DURATION FIELD
A 4-byte or 32-bit number that represents a checksum value for the entire frame
FRAME CHECK SEQUENCE
16 bits long, it contains a number of sub-fields that are used to describe how the frame itself should be processed
FRAME CONTROL FIELD
A certain section of the radio spectrum that’s been agreed upon to be used for certain communications
FREQUENCY BAND
A setup where fiber technologies are used for data deliver to an individual building
FTTB (FIBER TO THE BUILDING, BUSINESS, BASEMENT)
This is used in instances where fiber is actually run to each individual residence in a neighborhood or apartment buildling
FTTH (FIBER TO THE HOME)
This means that fiber technologies are used to deliver data to a single physical cabinet that serves a certain amount of the population
FTTN (FIBER TO THE NEIGHBORHOOD)
Another way to refer to FTTH and FTTB
FTTP (FIBER TO THE PREMESIS)
Another way to describe a fiber setup, where X can be one of many things
FTTX (FIBER TO THE X)
These are DSL technologies that provision speeds above 1.544 megabits per second
HDSL (HIGH BIT-RATE DIGITAL SUBSCRIBER LINES)
Access points are configured to only allow for connections from a specific set of MAC addresses belonging to devices you trust
MAC FILTERING
