section 5 Flashcards
Half Duplex
Only One thing can talk at a time
Full Duplex
you can both listen and talk at the same time
100BaseT4
100 mbps, 1024 nodes per hub, 100m, Cat 3, Four pairs
100BaseTX (100BaseT)
100mbps, 1024 nodes per hub, 100m, Cat5e, two pairs
100BaseFX
100mbps, 1024 nodes per hub, Multimode, 2km
Connect switches with Patch Cables (straight through cable)
Crossover cable
one end is 568a and one end is 568b
Uplink port
crossover port
Auto-sensing ports
automatically configure themselves
1000BaseCX
Twinax, 25 meters
1000BaseSX
Multimode, 500m
1000BaseLX
Single Mode, 5km
1000BaseT
Cat 6, 100m
10GBaseT
Cat6(55m), Cat6a(100m)
10GbaseSR/SW
Multimode, 26-400m
10GbaseLR/LW
Single Mode, 1310 nanometer, 10km
10GbaseER/EW
Single Mode, 1550 nanometer, 40km
Transceivers
Pluggable devices that allow you to keep one switch and use any of fiber connectors you want within that standard
Multisource agreement
can be used for any switch
Quad small for-factor pluggable
40 gigabit ethernet
Bidi
only one connection
Bridging loop
data will start zooming around infinitely and take down the broadcast domain
STP
solution for Bridging loop, will turn off one of the ports
Layer 2 Attack
requires a physical connection to your LAN. creates a flood
Flood Guard
similar to STP bc it turns off the flooded ports.
Speed Mismatch
2 switches with two different speeds
Uplink and Crossover
Cannot talk across switches. Use a crossover cable and the switches will be able to talk.
