Bit rate
The bit rate is also known as the speed of transmission, transmission rate or data
rate. It describes the number of bits transmitted per unit of time (usually 1 second).
Bridge
According to their OSI denition, bridges connect sub-network protocols on layer
2 of the OSI reference model
Broadcast
As its name suggests, a broadcast transmission involves transmission from one
point to all participants at the same time.
Bus
Buses are connection systems for electronic and electrical components. In
terms of topology, a bus is always a physical medium to which the individual
components are connected and which is terminated at both ends.
Category 5 / Kategorie 5
Designates conformity with the properties specied in IEC 11801. Category
5 (Cat.5) components can be used to set up networks which are suited to all
Ethernet transmission standards up to 100 Mbit/s based on twisted pair cables.
Category 5e
Cat. 5e is an equivalent version of TIA/EIA 568 compared with Cat. 5 of
IEC 11801 for use in 1.000BaseT networks.
CRC (Cyclic Redundancy Check)
CRC is an error detection process which reliably detects individual errors but only
detects multiple errors with a high level of probability.
Crossover cable
A crossover cable is a special patch cable where the transmit and receive cables
are swapped at one end. Crossover cables are usually used to connect two end
devices.
CSMA/CD (Carrier Sense Multiple Access with Collision Detection)
Access process in which the transmitters of a shared network only check the
network for availability before transmitting (is not needed for full duplex mode)
DHCP (Dynamic Host Conguration Protocol)
A specially congured server can use the DHCP to dynamically assign IP
addresses and other network parameters to computers in the network.
DTE (Data Terminal Equipment)
Every device in the network where a communication channel starts or ends. A
station (computer or host) in the network which is able to transmit or receive data.
