Cards

Term
bridge
Definition
A device that connects and pases packets between two network segments that use the same communications protocol. Operate in layer 2 of the OSI model...It use the MAC address to filter traffic from going all over the network.
Term
bridging
Definition
A technology in which a bridge connects two or more LAN segments.
Term
broadcast
Definition
A data packet that is sent to all nodes on a network. Broadcasts are identified by a bradcast address.
Term
broadcast address
Definition
A special address that is reserved for sending a message to all stations. Generally, a broadcast address is a MAC destination address of all 1s.
Term
broadcast domain
Definition
The set of all devices that will receive broadcast frames originating from any device within the set. Routers typically bound broadcast domains because routers do not forward broadcast frames.
Term
broadcast storm
Definition
An undersirable network event in which many broadcasts are sent simultaneoulsy across all network segments. A broadcast storm uses substantial network bandwidth and, typically, causes network time-outs.
Term
bus topology
Definition
A linear LAN architecture in which transmissions from network stations propagate the length of the medium and are received by all other stations.
Term
collision
Definition
In Ethernet,the result of two nodes transmitting simultaneoulsy. The frames from each device collide and are damaged when they meet on the physical medium.
Term
CSMA/CD
Definition
Carrier sense multiple access collision detect- A media-access mechanism where in devices that are ready to transmit data first check the channel for a carrier. If no-->TX; if yes-->NO TX.
Term
cut sheet
Definition
A rough diagram indicatiing where cable runs are located and the numbers of rooms they led to.
Term
Cut-through
Definition
A packet-switching approach that streams data through a switch so that the leading edge of a packet exits the switch at the output port before the pacekt finishes entering the input port. AKA on-the-fly packet switching.
Term
enterprise server
Definition
A server that supports all the suers on a network by offering services such as email or DNS.
Term
Ethernet
Definition
A baseband LAN specification that was invented by Xerox Corporation and developed jointly by Xerox, Intel, and DEC.
Term
Fast Ethernet
Definition
Any of a number of 100-Mbps Ethernet specifications. Fast Ethernet offers a speed increase 10 times that of the 10 BASE-T Ethernet specification, while preserving such qualities as frame format, MAC mechanism, and MTU.
Term
Fast-forwarding switching
Definition
Switching that offers the lowest level of latency by immediately forawrding a packet after receiving the destination address.
Term
Gigabit Ethernet
Definition
Any of a number of 1000-Mbps Ehternet specifications. Gigabit Ethernet offers a pseed increase 10 times that of the Fast Ethernet specification.
Term
IEEE 802.3
Definition
An IEEE LAN protocol that specifies an implementation of the physical laeyer and the MAC sublayer of the data link layer.
Term
IEEE
Definition
Institude of Electrical and Electronics Engineers- A professional organization whose activities include the development of communications and network standards.
Term
LAN
Definition
Local-Area-Network - A high-speed, low-error data network that covers a relatively small geographic area.
Term
LAN Switch
Definition
A high speed switch that forawards packets between data-link segments. Most LAN switches forward traffic based on MAC addresses. Often caterogize by approach methods.
Term
Latency
Definition
The delay between the time that a device requests access to a network and the time that it is granted permission to transmit.
Term
MAC
Definition
Media Access Control- A standardize data link layer address that is required for every port or device that connects to a LAN.
Term
microsegmentation
Definition
The division of a network into smaller segments, usually witht he intention of increasing aggregate bandwidth to network devices.
Term
network layer
Definition
layer 3 of the OSI model- this layer provides connectivity and path selection between two end systems.
Term
spanning Tree protocol
Definition
Bridge protocol that uses the spanning-tree algorithm...work around loop..and let router talk to each other to fix the looping problem.
