Physical Topology
Term
What are the three fundamental types of topology?
Definition
Bus, Ring, Star
Term
A physical topology in which all nodes on a network are connected without intervening connectivity devices.
Definition
Bus Topology
Term
A physical topology in which each node is connected to the two nearest nodes so that the entire network forms a circle.
Definition
Ring Topology
Term
A physical topology in which every node on the network is connected through a central connectivity device.
Definition
Star Topology
Term
A physical topology that combines characteristics of more than one fundamental topology.
Definition
Hybrid Topology
Term
A network topology in which each workstation participates in transmitting data
over the network.
Definition
Active Topology
Term
A network topology in which each node listens for, then accepts, data directed to it.
Definition
Passive Topology
Term
A single cable that connects all nodes on a network
without intervening connectivity devices.
Definition
Bus
Term
Resistors that stop signals after they have reached the end of the wire.
Definition
Terminators
Term
A phenomenon caused by improper termination on a bus topology network in which signals travel endlessly between the two ends of the network, preventing new signals from getting through.
Definition
Signal Bounce
Term
The capability for a component or system to continue functioning despite damage or malfunction.
Definition
Fault Tolerance
Term
Is a bus topology a passive or active topology?
Definition
Passive
Term
Is a ring topology a passive or active topology?
Definition
Active
Term
Is a star topology a passive or active topology?
Definition
Can be either; Depends on the connectivity device and other factors
Term
What common physical medium is used with a bus topology?
Definition
Coaxial Cabling
Term
What common physical mediums are used with a ring topology?
Definition
Fiber Optic Cabling, Twisted Pair Cabling

What common physical mediums are used with a star topology?
Definition
Fiber Optic Cabling, Twisted Pair Cabling
Term
Bus Topology: 1) Advantages? 2) Disadvantages?
Definition
1) Lower cost 2) Not scalable, Not very fault tolerant, Difficult to troubleshoot
Term
Ring Topology: 1) Advantages? 2) Disadvantages?
Definition
1) Data goes directly to its destination 2) Not very scalable, Not very flexible
Term
Star Topology: 1) Advantages? 2) Disadvantages?
Definition
1) Very fault tolerant, flexible, scalable 2) Costly, requires more cabling than bus or ring topologies
Term
Hybrid topology in which data is sent around a star in a ring pattern while using a central connectivity device.
Definition
Star-Wired Ring Topology
Term
Hybrid topology in which groups of workstations are connected to connectivity devices and networked via a bus.
Definition
Star-Wired Bus Topology
Term
Refers to the way in which data is transmitted between nodes.
Definition
Logical Topology
Term
Logically grouped network nodes that can communicate directly via broadcast transmissions.
Definition
Broadcast Domain
Term
The part of a network to which segments
and significant shared devices connect.
Definition
Backbone
Term
Type of backbone that consists of two or more devices connected to each other by a single medium in a daisy-chain fashion.
Definition
Serial Backbone
Term
Type of backbone that consists of a number of intermediate connectivity devices connected to one or more central connectivity devices in a hierarchy.
Definition
Distributed Backbone
Term
Type of backbone that uses a router or switch as the single central connection point for multiple subnetworks.
Definition
Collapsed Backbone
Term
Type of backbone that consists of more than one connection from the central router or switch to each network segment.
Definition
Parallel Backbone
Term
A linked series of devices.
Definition
Daisy Chain
Term
A component of a network’s logical topology that determines how connections are created between nodes.
Definition
Switching
Term
A switching method in which a connection is established between two network nodes before they begin
transmitting data.
Definition
Circuit Switching
Term
A switching method that involves breaking data into smaller units before transmission.
Definition
Packet Switching
Term
A switching method that enables any Data Link layer protocol to carry multiple Network layer protocols.
Definition
MPLS (Multiprotocol Label Switching)
Term
A specification that guarantees delivery of data within a certain time frame.
Definition
QoS (Quality of Service)
Term
Method of controlling how network nodes access the communications channel.
Definition
Access Method
Term
A network access method specified for use by IEEE 802.3 networks in which each node waits its turn before transmitting data in order to avoid interfering with other nodes’ transmissions. If a node’s NIC determines that its data has been involved in a collision, it immediately stops transmitting.
Definition
CSMA/CD
Term
A CSMA/CD process in which, upon detecting a collision, a station issues a special 32-bit sequence to indicate to all nodes on an Ethernet segment that its previously transmitted frame has suffered a collision and should be considered faulty.
Definition
Jamming
Term
The portion of a network in which collisions occur if two nodes transmit data at the same time.
Definition
Collision Domain
Term
The length of time data takes to travel from one point on the segment to another point.
Definition
Data Propagation Delay
Term
A networking rule that states: Between two communicating nodes, the network cannot contain more than five network segments, connected by four repeating devices, and no more than three of the segments may be populated.
