This is how bits are represented with a pattern of voltage or no voltage
What 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 layer of the OSI model is responsible for specifying the encapsulation method used for specific types of media
What is data link?
200
This is type of signaling does require a clock signal and therefore start and stop flags are needed
What is asynchronous ?
200
The twisting of wire pairs is done to prevent this
What is to limit 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
The throughput of a FastEthernet network is 80 Mb/s. The traffic overhead for establishing sessions, acknowledgments, and encapsulation is 15 Mb/s for the same time period. The goodput for this network is this.
What is 65 Mb/s?
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 cable ?
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
The magnetic field cancellation effect is enhanced in UTP cables because of this
What is by increasing and varying the number of twists in each wire pair ?
400
This measure of bandwidth uses a million bits per second
What is Mbps or Megabits per second ?
400
Although more expensive, this media is used as backbone cabling because of its ability to carry singles long distances and immunity to electrical interference.
What is fiber optic cable ?
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
two strands of fiber used for a single fiber optic connection because of this
What is they allow for full-duplex connectivity?
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 ?
500
This sub-layer allows for access to various network technologies
What the MAC (Media Access Control) Layer ?
500
This topology defines how the end devices are interconnected.
What is the Physical topology ?
500
A network administrator is required to upgrade wireless access to end users in a building. To provide data rates up to 1.3 Gb/s and still be backward compatible with older devices, this wireless standard should be implemented
