B
Backplane
A kind of electrical circuit board, including the circuit and
socket. Other circuit boards or electrical devices on the board
can be inserted into the circuit or socket. In the computer
system, the backplane is synonymous with the mother board
or belongs to the mother board.
Baud rate
Times of signal changes every second on a transmission link.
In general, there are only two types of signal status, so the
baud rate is the number of bits transmitted every second.
Since lower-layer transmission will occupy some bandwidth,
so user data are not necessarily transmitted according to the
rated baud rate.
C
Card
An electronic module, composed of the chip and other
electronic components installed on a flat and hard Printed
Circuit Board (PCB). The PCB has conductive circuits for
connecting these components.
E
Ethernet
It is founded by Xerox Corporation and defined by DEC,
Intel, and Xerox. Ethernet is the most widely used LAN. Its
rates include 10 Mbit/s, 100 Mbit/s, and 1000 Mbit/s.
Ethernet adopts CSMA/CD mechanism and complies with
IEEE 802.3 standard.
F
Fiber
Filamentous optical waveguide composed of electrical
materials, used to conduct electromagnetic energy in the form
of optical wave.
Frame
It is a data transmission unit, composed of several parts, each
of which has different functions.
I
In-band Network
Management
The NMS exchanges information with a device through
service networks.
L
Light Amplification by
Stimulated Emission of
Radiation (LASER)
A laser is a device that emits light through a process of
optical amplification based on the stimulated emission of
electromagnetic radiation.
