Media Flashcards
What are the different types of signals used to transmit data?
Radio waves, Light pulses, Electric pulses
What are the two types of twisted pair cables?
UTP (unshielded twisted pair) STP (Shielded Twisted Pair)
What are the 4 categories of UTP used?
Cat 3(10mbps 16mhz) Cat 5(100mbps 100mhz) Cat 5e(1000mbps 100mhz) Cat 6(1000mbps 250mhz)
What are the two types of UTP connectors?
RJ-11 and RJ-45
What is the interference called when media cables are bundled together?
Crosstalk
How do fiber optic cables transmit signals ?
Through glass or plastic fibers
What do Coaxial cables transmit signal through ?
Copper Wire
Which organisation sets the standards T568A and T568B for twisted pair(Ethernet) Wiring schemes?
TIA/EIA
Connecting like-devices(end devices) requires what type of Ethernet cable? Straight- Through or Crossover
Crossover. Straight through uses different wire pairs to listen and talk, which makes it better suited for End-Device to Intermediary Devices like switches and routers
What command is used to check the connection between two end devices?
Ping command. Type: ping[space][IP address]
What command is used to check the route data packets take from sender to destination?
traceroute or tracert(in windows)
What organisation sets the Ethernet and wireless standards?
IEEE
What is a Ethernet MAC address?
The Physical Address given to NiC(network interface cards) when manufactured
