- 1DhcpDynamic Host Computer Protocol
how the computer is assigned an ip address (however there is another method) - 2Back BoneTransmission of data that connects small segments into the larger network
- 3serial"daisy chaining" a series of routers and switches in a chain connected to the host.
- 4Distributeda series of hubs with a central device that is connected to other switches can easily extended, scaleable
- 5Collapsible backboneone central hub /router is connected to individual switches
- 6parallelimilar to the collapse back bone server however it has two routers and double cabling
- 7ICSIndustrial Controll sysytem
- 8SCADAsupervisory control and data Acquisitions
- 9DCSdistibuted control system
- 10PLC'SProgrammable Logical controllers
- 11Centralized networka data base main frame has all the programs and runs iton the mainframe
- 12Peer to peerdecentralized because any computer can be used to share and get resources
- 13Csma Cdcarrier sense multiple access
Cd: collision detection - 14Csma Cacarrier sense multiple access
CA: collision avoidance - 15SimplexOne way transmission of data
- 16Half duplexTwo way transmission, but only one direction at a time
One device send the other receives
Roles can switch - 17Full duplexSimultaneous two way transmission of data
Devices can send and receive at the same time(good for configuring devices) - 18OSI Modelunknown

- 26UTP• no shielding
• Typically 4 pair
• In expensive - 27STP• Shielded around conductors
• Typically contains four pairs of stranded conductors
• More expensive than UTP - 28Standards for TIA/EIA category 1Voice Transmission

used for safety reasons so it doesn’t give of black smoke. - 36omni-directionaldirects the signal in all directions
- 37Uni-Directionaldirects the signal in one direction.
must be exact when positioning. - 38DCFdistributed coordination Function
functions as a CA method that controls access to the physical medium. - 39SSID BROADCASTScontinuous announcement by a wireless access point that transmits its name, or ssid, so that it is discoverable by wireless devices searching for a network connection
Can be referred as a beacon. - 40PHYSICAL BUS TOPOLOGYWhere all the nodes are connected in a linear format and T-connectors connect each node directly.
Slow transmission rate
10base2 / 10 Mgbs uses thin-net wiring - 41PHYSICAL STARUsing central connectivity device, such as a switch , which individual physical connection to each node if the central unit goes down the whole system goes down
- 42PHYSICAL MESHeach node is directly connected to each other. Allows nodes to communicate at the same time. Dedicated links with other nodes(no congestion on the line so data travels fast) very reliable (no nodes can be isolated)
very expensive - 43PHYSICAL RINGEach node is connected to the two nearest nodes: the upstream and downstream neighbors.
The flow is uni-directional - 44HYBRIDExhibits the characteristics of one or more topologies
- 45Logical Ring topologyUsed in token ring. Used to connect to mainframes traditionally. Send data out, or takes it in and works in a ring formation
- 46Logical StarCommon in LAN's
- 47Logical BusData is sent all at the same time regardless of the physical wiring. Data flows in a single, continuous stream from the sending node to all other nodes, the medium is shared
Uses hubs - 48list the components to a mac addressThe MAC address is a 6 digit address.
the first three digits are the manufacturers code
and the last three are unique to the computer - 4910base-2 what is the IEEE SPECS, MEDIUM, AND DISTANCE?IEEE: 802.3A
