COMMUNICATIONS OA COMPREHENSIVE
STUDY GUIDE WITH SOLUTIONS
◉ Bandwidth Allocation Protocol (BAP).
Answer: Allows the number of lines used by MLPPP to change on
demand. (14)
◉ bandwidth shaper.
Answer: Used to prioritize network packets to ensure quality of
service for time-sensitive applica-tions such as VoIP; also known as a
traffic shaper. (12)
◉ baseband.
Answer: Method of transmitting data in the form of a digital signal,
using the entire bandwidth of a cable. (2)
◉ baseline.
Answer: Measurement of performance characteristics that can be
used at a later date to determine if the network or server is
performing satisfactorily. (16)
◉ basic disk.
,Answer: Term applied to the old system of hard disk drive
configuration. (7)
◉ Basic Rate ISDN (BRI-ISDN).
Answer: ISDN cat-egory that consists of three conduc-tors: two B
channels, referred to as bearer channels, and one D channel, referred
to as the delta channel. (14)
◉ basic service set (BSS).
Answer: Group of wireless devices connected as a network. (4)
◉ biometrics.
Answer: Science of using unique physical features of a person to con-
firm that person's identification for authentication purposes. (15)
◉ bipolar digital signal.
Answer: Digital signal that fluctuates between a positive five-volt
level and a negative five-volt level. (5)
◉ bit rate.
Answer: Number of bits used to repre-sent the amplitude of the
analog signal. (12)
,◉ blackout.
Answer: Total loss of electrical energy. (16)
◉ blade server.
Answer: Extremely thin server designed to allow a large number of
servers to be mounted in a small space. (9)
◉ Bluetooth.
Answer: Short-range, wireless system that is designed for limited
distances. (4)
◉ boot loader.
Answer: Program that starts an op-erating system load process. (8)
◉ boot partition.
Answer: Contains the files needed to operate the computer. (17)
◉ Border Gateway Protocol (BGP).
Answer: Internet routing protocol that supports the exchange of
routing information between autonomous networks. (11)
◉ bridge.
, Answer: Can be used to divide the network into smaller segments,
reducing the chance of collisions. (1)
◉ broadband.
Answer: Method of transmitting data in the form of several analog
signals at the same time. (2)
◉ Broadband ISDN (B-ISDN).
Answer: ISDN category designed to carry multiple frequencies. (14)
◉ broadcast frame.
Answer: Frame in which the destination address is filled with all
ones; intended for every computer on a network. (5)
◉ broadcast storm.
Answer: Occurs when the number of collisions reaches a point that
the network is flooded with a continuous number of collisions and
rebroadcasts. (6)
◉ brouter.
Answer: Combines router and bridge functions. (1)
◉ brownout.
