TERMINOLOGY

10BASE-T

A designation for the type of wiring used by Ethernet networks with a data rate of 10 Mbps. Also known as Category 3 (CAT 3) wiring. See also data rate, Ethernet.

100BASE-T

A designation for the type of wiring used by Ethernet networks with a data rate of 100 Mbps. Also known as Category 5 (CAT 5) wiring. See also data rate, Ethernet.

ADSL (Asymmetric Digital Subscriber Line)

The most commonly deployed flavor of DSL for home users. The term asymmetrical refers to its unequal data rates for downloading and uploading (the download rate is higher than the upload rate). The asymmetrical rates benefit home users because they typically download much more data from the Internet than they upload.

analog

Of data, having a form is analogous to the data's original waveform. The voice component in DSL is an analog signal. See also digital.

ATM (Asynchronous Transfer Mode)

A standard for high-speed transmission of data, text, voice, and video, widely used within the Internet. ATM data rates range from 45 Mbps to 2.5 Gbps. See also data rate.

authenticate

To verify a user's identity, suchas by prompting for a password.
