|
daisy chain
|
a linked series of devices
|
|
|
serial backbone
|
two or more devices connected to each other by a single medium in daisy chain fashion
|
|
|
distributed backbone
|
a number of intermediate connectivity devices connected to one or more central connectivity devices, such as switches or routers
|
|
|
collapsed backbone
|
uses a router or switch as the single central connection point for multiple subnetworks
|
|
|
parallel backbone
|
most robust. consists of more than one connection from the central router or switch to each network segment.
|
|
|
circuit switching
|
a type of switching in which a connection is established between two network nodes before they begin transmitting data.
|
|
|
packet switching
|
most popular method of switching. breaks data into packets before they are transported
|
|
|
MPLS (Multiprotocol label switching)
|
switching that enables multiple type of layer 3 protocols to travel over any one of several connection-oriented layer 2 protocols.
|
|
|
CSMA/CD (Carrier Sense Multiple Access with Collision Detection)
|
access method used by all ethernet networks. listens for no other transmissions, allows multiple nodes to monitor traffic
|
|
|
access method
|
a networks method of controlling how network nodes access the communications channel
|
|
|
jamming
|
indicating to the other nodes that the previous transmission was faulty
|
|
|
collision domain
|
portion of the network in which collisions occur if two nodes transmit data at the same time
|
|
|
data propagation delay
|
the length of time data take to travel from one point on the segment to another point
|
|
|
10Base-T
|
10 mbps, baseband, twisted pair
|
|
|
5-4-3 rule of networking
|
rule that states between communicating nodes, the network cannot contain more than 5 network segments connected by 4 repeating devices, and no more than 3 of the segments may be populated (at least 2 must be unpopulated)
|
|
|
What are the rules regarding segments and repeating devices?
|
no more than 3 segments connected by 2 repeating devices
|
|
|
PoE (name acronym and the 802 standard)
|
Power over Ethernet, 802.3af
|
