100
This is how bits are represented with a pattern of voltage or no voltage
What is is 0 and 1 ‘s ?
100
These types of interference can distort and corrupt signals carried on copper wire caused by fluorescent lights or electrical motors
What is EMI (Electromagnetic Interference) and RFI (Radio Frequency Interference) ?
100
This sub-layer identifies what network layer protocol is used.
What is LLC (Logical Link Control)?
100
This topology connects devices to a central point
What is a Star or hub and spoke topology ?
100
This physical address is used in an Ethernet frame for the source and destination.
What is MAC address ?
200
This is type of signaling does require a clock signal and therefore start and stop flags are needed
What is asynchronous ?
200
The interference of signals across two pairs of wires..
What is crosstalk?
200
These two sub-layers make up the data-link layer
What are LLC (Logical Link Control) and MAC (Media Access Control) ?
200
This topology is found in a FDDI (Fiber Distributed Data Interface) network.
What is Ring topology ?
200
This wireless standard operates at 2.4 GHz and 5 GHz simultaneously
What is 802.11n ?
300
This signaling uses an evenly spaced bit time and includes a clock signal.
What is synchronous ?
300
This cable has 568A on one end and 568B on the other end.
What is a crossover?
300
This field is placed in the trailer of a frame and is used for error detection.
What is the FCS (Frame Check Sequence) ?
300
CSMA/CD is used in this type of logical topology.
What is Contention Based Access or non-deterministic?
300
Consideration should be given to these three areas when designing wireless networks.
What is Coverage area, Interference, and Security ?
400
This measure of bandwidth uses a million bits per second
What is Mbps or Megabits per second ?
400
This media type can be used across several kilometres.
What is fibreoptics
400
This is used by the MAC layer to indicate the beginning and end limits of a frame.
What are frame start and stop bits or indicators ?
400
The “mechanism” to access the network is known as this topology type.
What is Logical topology?
400
This method is used by Wireless frames to access the media.
What is CSMA/CA (Carrier Sense Multiple Access / Collision Avoidance ?
500
This measurement is the result of Throughput minus the overhead of non-useable data traffic
What is Goodput ?
500
This multimode fiber cable uses the same type of connector at both ends
What is SC-SC connector
500
This sub-layer allows for access to various network technologies
What is the MAC (Media Access Control) Layer ?
500
This topology defines how the end devices are interconnected.
What is the Physical topology ?
500
This type of frame requires only 1 byte for each physical address
What is PPP ?
