feature.
BNC Connector
This is a standard connector used to connect IEEE 802.3 10Base-2 coaxial cables to
Media Access Unit (MAU).
Boot Loader
This is a chip installed into a printed circuit board used to send executable boot
commands to a network device.
Bps
Stands Bits per second. Typically called bps. Refer to bit rate.
Cable Modem
This device converts analog signals to digital signals in order to enable the Internet
through a cable network. Since telephone networks are made of copper wires and
cable networks are made of coaxial and optical cables, the bandwidth of cable
networks are much wider than that of telephone networks. However, the
modulation/demodulation technology, which converts digital to analog and vice versa,
is required for cable networks when data is transferred.
Call Center
Call Center is a central place where calls from customers and other people are
processed systematically. Computer automation is implemented in Call Center to some
degree. Typically, Call Center processes many calls simultaneously, categorizes calls,
connects the calls to personnel, and records calling logs automatically. Call Center is
typically used for mail order catalog firms, telemarketing firms, customer centers for
PC products, and large enterprises that sell products or provide services.
Caller ID
Caller ID is a call service that enables the phone number of the caller to be sent to the
recipient. To see the phone number, a digital reader should be installed into the phone.
Category 5 cabling
One of the five-level UTP cable connection methods specified by the EIA/TIA-586
standard. Category 5 cabling enables data to be transferred at a rate of up to 100Mbps.
CBR
Stands for Constant Bit Rate. The ATM network QoS class CBR defined by ATM
Forum is used for a connection device that is based on a precise clock processing
method to ensure untwisted data transfer.
CES
Stands for Circuit Emulation Service. This service allows you to multiplex multiple
line emulation streams for voice and video with packet data through a single
high-speed ATM link without using a separate ATM access multiplexer.
Checksum
This is a method for checking the integrity of transferred data. Checksum is an integer
calculated from the octet sequence obtained by a series of operations. This value is
calculated by the recipient again for verification.
Coaxial cable
This coaxial cable is made of an external cylinder-type conductor that wraps an
internal wire conductor.
Examples of the coaxial cables used for LAN include
50Ω cables used for digital signal processing and 75Ω cables used for high-speed
