Flashcards in Chapter 6 Deck (24):
(Network Interface Card) connects a computer to a computer network.
(Modulator/Demodulator) a device that modulates signals to encode and demodulates to decode.
connects two dissimilar media types such as twisted pair with fiber optic cabling.
receives a signal and retransmits it at a power, or onto the other side of an obstruction, so that the signal can cover longer distances.
a node with a number of links that greatly exceeds the average.
joins wires from several stations in a star configuration
regenerates signals on the output side to keep the signal strong
A physical region of a LAN in which data collisions can occur
functions for network management, bridging, routing and switching.
connects two or more local area networks at layer 2.
connecting multiple wires, allowing them to communicate simultaneously
switches on OSI layer 2 like an ordinary network switch and provides extra functions on higher OSI layers.
distribute user requests to servers based on Layer 7 payload.
(Virtual LAN) groups users by logical addresses into a virtual LAN through a switch or router.
provides network access to many clients by sharing a set of lines or frequencies
Cross connecting two or more ports on a network switch so that traffic can be simultaneously sent to a network analyzer or monitor connected to another port.
port authentication, port-based authentication
limits access to a specific port to just certain MAC addresses.
(STP) Spanning Tree Protocol
used by switches when multiple switches are used in the same network
PoE (Power over Ethernet)
safetly transfers power over Ethernet cabling
(Channel Service Unit/Data Service Unit) used to convert a digital signal from one frame format to another
used to move packets around a larger network
how fast a specific port on the router is able to send/receive data
used to prevent unauthorized packets into the network
