Cards

Term
BUS
Definition
A topology in which a single cable connects all nodes
Term
COLLISION
Definition
In Ethernet networks, the interference of one node's data transmission with anothers.
Term
DAISY
Definition
A ____-chain is simply a linked series of devices.
Term
DATA
Definition
The ____ portion of an Ethernet frame may contain 46-1500 bytes of information
Term
DOMAIN
Definition
On an Ethernet network, a collision ____ is the portion of a network in which collisions occur if two nodes transmit data at the same time.
Term
ETHERNET
Definition
All ______networks, independent of their speed or frame type, use an access method called CSMA/CD.
Term
HYBRID
Definition
A complex combination of pure topologies.
Term
LOGICAL
Definition
A type of topology in which the characteristic of network transmission reflects the way in which data is transmitted between nodes
Term
PADDING
Definition
The bytes added to the data portion of an Ethernet frame to ensure this field is at least 46 bytes.
Term
PARALLEL
Definition
A type of backbone that consists of more than one connection from the central router or switch to each network segment.
Term
PHYSICAL
Definition
A type of topology in which the physical layout of a network depicts a network in broad scope.
Term
PREAMBLE
Definition
The field in an Ethernet frame that signals to the receiving node that data is incoming and indicates when the data flow is about to begin.
Term
REACH
Definition
In the 10GBase-LR standard, the L stands for long ____.
Term
REASSEMBLES
Definition
In packet switching, when packets reach their destination node, the node ____ them based on their control information.
Term
REPEATER
Definition
In a ring network, each workstation acts as a(n) ____ for the transmission
Term
SERIAL
Definition
A type of backbone consisting of two or more internetworking devices connected to each other by a single cable in a daisy chain.
Term
SHIM
Definition
Collectively, MPLS labels are sometimes called a ____.
Term
STAR
Definition
A physical topology in which every node is connected through a central device. Most Ethernet networks use this.
Term
SWITCHING
Definition
A component of a network's logical topology that manages how packets are filtered and forwarded between nodes.
Term
TERMINATOR
Definition
A resistor that is attahed to each end of a bus-topology network. Without these, the bus network would suffer from signal bounce.
Term
TYPE
Definition
The Ethernet_II frame type contains a 2-byte ____ field which differentiates it from the older Ethernet_802.3 and Ethernet_802.2 frame types.
Term
WANS
Definition
Given their long-distance capabilities, 10GBase-ER and 10GBase-EW are best suited for use on ____.
