______ is a disturbance caused by the electric or magnetic fields of a signal on one wire to the signal in the adjacent wire.
What is crosstalk?
100
_______ topologies directly connect two physical nodes.
What is point-to-point?
100
Each ______ type has three basic parts, the Header, the Data, and a Trailer
What is a Frame?
100
A transmission in which the carrier frequency varies in accordance with the signal.
What is Amplitude modulation (AM)?
100
A single b7yte that indicates the beginning or end of a frame. The flag field consists of the binary sequence 01111110
What is a Flag?
200
__________ cabling is the most common networking media. Terminated with RJ-45 connectors , is used for interconnecting network devices such as routers or switches.
What is Unshielded twisted-pair (UTP).
200
End systems are connected to their respective neighbor, they were used in legacy networks.
What is Ring?
200
_____ is the beginning of every Header and consists of 8 bytes.
What is the Preamble?
200
Data signals are sent along with a clock signal that occurs at evenly spaced time durations referred to as the bit time.
What is Synchronous?
200
Indicates the upper-layer service contained in the frame or the length of the frame.
What is Type field?
300
_______ gets its name from that fact that there are two conductors that share the same axis. It consists of A Copper Conductor, Plastic Insulation, Braided Shielding, and Outer Jacket.
What is Coaxial Cable?
300
A WAN version of star topology in which a central site interconnects branch sites using point-to-point links.
What is Hub-and-spoke?
300
A CRC value used to check for damaged frames.
What is Frame Check Sequence (FCS)?
300
A method of transmission technique in which the amplitude of the carrier varies in accordance with the signal.
What is Amplitude modulation (AM)?
300
Included after the data to form the trailer, these frame fields are used to insure frame integrity.
What is Error Detection?
400
_____ is very thing and comprised of two kinds of material and protected by an outer shield made of A PVC Jacket, Cladding, Buffer material, and the Core of the wire.
What is Fiber-Optic Cabling?
400
This topology provides high availability, but requires that every end system be interconnected to every other system. Each link is essentially a point-to-point link to the other node.
What is Full Mesh?
400
This part of the frame is always variable and never has a set byte size.
What is the Data?
400
Data signals are transmitted without an associated clock signal. The time spacing between the data characters or blocks can be of arbitrary duration, meaning that the spacing is not standardized. Frames need start and stop flags.
What is Asynchronous?
400
This is the process that takes data and segments it into manageable packets and finally provides a frame to be broken down into bits for transportation.
What is Encapsulation?
500
This mode of dispersion uses a larger core, greater dispersion, uses LED as light sources for information, and applied in shorter distances generally up to 2 km.
What is Multimode?
500
All end systems are chained to each other and terminated in some form on each end. Infrastructure devices such as switches are not required to interconnect the end devices.
What is Bus?
500
Indicates the upper layer service contained in the frame or the length of the frame.
What is Type field?
500
A technique in which the analog signal, such as a voice, is converted into a digital signal by sampling the signal's amplitude and expressing the different amplitudes as a binary number.
