Behavior learning engines (BLEs) are platforms intended to enable the discovery, visualization and analysis of recurring, complex, multiperiod patterns in large operational performance data sets. If such engines are to realize their intent, they must support four layers of cumulative functionality:
Variable designation—this supports the selection of the system properties that are to be tracked by the platform and how those properties are to be measured
Variable value normalization&mdahs;this is the automated ability to determine (usually by an algorithm that regresses measurements) what constitutes the normal or usual values assumed by the system property measuring variables
Observational dependency modeling—this is a set of tools for linking the individual property measuring variables to one another, where the links represent some kind of dependency among the values taken by the linked variables; commercially available BLEs differ significantly with regard to the degree to which the dependencies must be pre-established by the vendor or user and the degree to which the dependencies are themselves discovered by BLE algorithms working on the performance data sets being considered
Assessment—the means by which, once the normalized values and dependency map are determined, the resulting construct can be used to answer questions about the values assumed by some variables, based on the values assumed by others

Baud is a unit of signaling speed. The speed in bauds is the number of discrete changes per second in some aspect of a signal (e.g., voltage in a wire). Transmission speeds are now more commonly measured bits per second (bps), rather than bauds. The two terms were roughly synonymous until modems began to exceed 2,400 bps, after which they diverged more widely as modem speed has increased. Modems now use coding techniques to transmit more than one bit per baud, making their true baud ratings irrelevant.

There are two types of battery-powered radio frequency identification (RFID) tags: battery-assisted passive (BAP) tags and active tags, which are used to collect and communicate asset-level information. BAP tags, which were standardized in 2010 in ISO/IEC 18000-6C:2010 Class 3, use a battery for operating the internal circuitry that facilitates the collection, processing and storage of ancillary information. The additional energy may also be used to boost the communication process in difficult usage scenarios, such as personnel tags. Active (Generation 2 Class 4) tags use batteries to power all functions of the tag—the receiving and transmitting of a signal, as well as the power for the processing and memory chips. Both solutions differ from passive-only tags, where there is no battery for communication, additional processing or storage. Although active and BAP tags can technically be implemented at all frequencies in which RFID is used, they are most common at 433 MHz, 900 MHz and 2.4 GHz.

Batch processing is the processing of application programs and their data individually, with one being completed before the next is started. It is a planned processing procedure typically used for purposes such as preparing payrolls and maintaining inventory records.

Basic trading area (BTA) is a geographic area designation that was used for the allocation of 800MHz cellular licenses to mobile service providers in the U.S., which determines where they can operate. Each metropolitan trading area (MTA) is made up of several BTAs. There are 493 BTAs and 51 MTAs in the U.S.

The basic input/output system (BIOS) is the part of an operating system that links the specific hardware devices to the software. It obtains the buffers required to send information from a program to the hardware/desktop receiving the information.
Industry:Technology
Baseband is the transmission of a signal in its original, unmodulated form. A baseband signal can be analog (e.g., originating from a telephone) or digital (e.g., originating from a computer).
Industry:Technology
A base transceiver station (BTS) is a fixed radio transceiver in any mobile network. The BTS connects mobile devices to the network. It sends and receives radio signals to mobile devices and converts them to digital signals that it passes on the network to route to other terminals in the network or to the Internet.
Industry:Technology
A base station controller (BSC) is a network element that controls and monitors a number of base stations and provides the interface between the cell sites and the mobile switching center (MSC).
Industry:Technology
Within a mobile radio system, a base station is a fixed radio station providing communication with mobile stations and, where applicable, with other base stations and the public telephone network.
