100BaseT

100 Mebabit per second baseband Fast Ehternet specification using UTP wiring. Like the 10BaseT technology on which it is based, 100BaseT sends link pulses over the network segment when no traffic is present. However, these link pulses contain more information than those used in 10BaseT.

10BaseT

10 Megabit per second baseband Ethernet specification using two paris of twisted-pair cabling (Category 3, 4 or 5): one pair for transmitting data and the other for receiving data. 10BaseT has a distance limit of approximately 100 meters per segment.

Active Channel

An Active Channel is a frequently updated information residing on a Web server.

ActiveX

ActiveX is a set of technologies from Microsoft that enables interactive content for the World Wide Web. Before ActiveX, Web content was static, 2-dimensional text and graphics. With ActiveX, Web sites come alive using multimedia effects, interactive objects, and sophisticated applications that create a user experience comparable to that of high-quality CD-ROM titles. ActiveX provides the glue that ties together a wide assortment of technology building blocks to enable these "active" Web sites.

Address

URL (Uniformed Resource Locator) is more frequently used for this purpose.

ADN

(Advanced Digital Network). A 56kbps dedicated communication line.

ADO

Microsoft Data Access Component Used primarily as a scripting language interface to OLE DB or ODBC data access ActiveX or Active Data Objects.

ADSL

Asymmetric Digital Subscriber Line (ADSL) is a fast-growing new technology that converts existing twisted-pair copper lines into high-speed, high-bandwidth digital lines.

Anonymous FTP (Anon FTP)

A method for downloading and uploading files using FTP protocol without having a username or a password.  "Anonymous FTP" indicates that a user may log into the remote system as user "anonymous" with an arbitrary password. A common convention is that the user's email address is supplied as the password, e.g. "yourname@yoursite".

Asynchronous Transfer Mode (ATM)

Asynchronous Transfer Mode. International sandard for cell relay in which multiple service types (such as voice, video, or data) are conveyed in fixed-length (53-byte) cells. Fixed-length cells allow cell processing to occur in hardware, thereby reducing transit delays. ATM is designed to take advantage of high-speed transmission media such as E3, SONET, and T3.
