| 56K Modem |
A modem is a device that converts digital
signals, from a computer, into analog signals for transmission over telephone
lines. A modem also converts incoming analog signals into digital signals.
56K means that this type of modem has the ability to transmit at up to 56,600
bps. |
| ADSL |
ADSL is a type of high-speed Internet access for consumers.
ADSL stands for Asymmetric Digital Subscriber Line. This is a technology
that allows for digital transmission over existing telephone lines. The
term 'asymmetric' refers to the fact that the speed that you send data can
be different than the speed that you can receive data. Therefore, a typical
user will have a faster download speed than upload speed through ADSL. ADSL
service is typically many times faster than a 56k modem while allowing for
regular phone/voice usage simultaneously on the same telephone line. ADSL
service is an "always-on" type of connection, which is especially
vulnerable to hacker attacks. Users can prevent unauthorized access with
a software firewall product. |
| Address |
See email address and host address. |
| Agent |
The commercial version of the Free Agent newsreader. |
| Alias |
A short name used to represent a more complicated one.
Often used for e-mail addresses or host domain names. |
| Analog |
A form of electronic communication using a continuous
electromagnetic wave, such as television or radio. Any continuous wave form,
as opposed to digital on/off transmissions. |
| Archive |
A repository of files available for access at an Internet
site. Also, a collection of files, often a back-up of a disk or files saved
to tape to allow them to be transferred. |
| Article |
Message submitted to a UseNet newsgroup. Unlike an e-mail
message that goes to a specific person or group of persons, a newsgroup
message goes to directories (on many machines) that can be read by any number
of people. |

| ASCII |
Data that is limited to letters, numbers, and punctuation. |
| Attribute |

the HTML language. HTML commands or tags can be more specific when attributes
are used. Not all HTML tags utilize attributes. |
| Acceptable Use Policy
(AUP) |
The restrictions that a network segment places on the
traffic it carries. (These polices used to be more prevalent when the government
was running the Internet backbone.) |
| Backbone |
The major communication lines of a network. |
| Bandwidth |
Bandwidth refers to how much data is transmitted over
a given period of time. For digital devices, bandwidth is measured in bits
per second (bps). For analog devices, bandwidth is measured in Hertz (Hz). |
| Bulletin Board System
(BBS) |

upload and download files and leave messages for other users. |

graphics files, programs, and sound files. |
| BinHex |

so that they can be sent through e-mail. |
| Bit |

eight bits in a byte. |
| Bookmarks |

URL's you access frequently. |
| Bounce |

e-mail you sent wasn't delivered. Usually contains an error code and the

character. Compare to bit. |
| Cable Modem |
Cable modem service is a type of high-speed
Internet access offered by local cable companies for consumers. Using the
same coaxial cable used for TV signals, the speed of downloading data is
typically many times faster than a 56K modem. Since cable TV was designed
as a broadcast system, the cable is shared amongst many people in a small
area, so download speeds can vary greatly throughout the day or week. Typically,
upload speed is restricted to only 56Kbps, more than enough for normal,
fast "surfing" of the Internet. Cable modem service is an "always-on"
type of connection, which is especially vulnerable to hacker attacks. Users
can prevent unauthorized access with a software firewall product. |
| Channel |

and Internet host names. |

of the Internet, the amount of data downloaded is many times greater than
the amount of data uploaded. |
| DSL |
DSL is a type of high-speed Internet access for consumers.
DSL stands for Digital Subscriber Line. This is a technology that allows

many times faster than a 56K modem while allowing for regular phone/voice
usage simultaneously on the same telephone line. Although DSL service does
not exist in all areas, it is currently more available than cable modem
service. DSL service is an "always-on" type of connection, which
is especially vulnerable to hacker attacks. Users can prevent unauthorized
access with a software firewall product. |
