authorization

authorization The process of granting or denying access to a network resource. Most computer security systems are based on a two-step process, sometimes more. The first stage is authentication, which ensures that a user is who he or she claims to be and in some cases, that the user is not already on the system. The second stage is authorization, which allows the user access in varied degrees to various resources based on the preassigned privileges associated with the user’s identity.

Basic Rate Interface (BRI)

Short for Bearer-channel, the main data channel in an ISDN connection. Basic Rate ISDN (BRI) service consists of two 64 Kbps B-channels, and one D-channel for transmitting control information.

Bipolar 8-Zero Substitution, a coding scheme that maintains ones density.

A common bus at the rear of the computer chassis connecting each circuit card slot to the other parts of the system. Motherboards on modern PCs are a general equivalent. It also distributes low-voltage AC and DC, filtered and un-filtered power to each slot.

The amount of data that can travel through a channel in a given period of time. Bandwidth is usually measured in cycles per second (hertz) or in bits per second (BPS). The larger the bandwidth, the more information the network can handle. ISDN is usually 64KB, 128KB or 256KB.

ASDL and DSL are generally faster than ISDN and sometimes faster than cable. Cable connections are usually 500KB or 1MB. T1 is 1.5MB and T3 is 45MB.

Basic Rate Interface is an Integrated Services Digital Network (ISDN) interface typically used by smaller sites and customers. This interface consists of a single 16 Kbps Data (or "D") channel plus 2 Bearer (or "B") channels for voice and/or data.
