What is Belden?
The conducting core and the wire mesh must always be kept separate from each other. If they touch, the cable will experience a ___________.
What is a short?
This cable is flexible coaxial cable about 0.64 centimeters (0.25 inches)thick.
What is Thinnet Cable?
_________ cable is a relatively rigid coaxial cable about 1.27 centimeters (0.5 inches) in diameter.
What is Thicknet?
To organize bits into frames; to provide hop-to-h?
What is the Data Link Layer?
At one time this cable was the most widely used network cabling.
What is coaxial cable?
An __________________ occurs when any two conducting wires or a conducting wire and a ground come into contact with each other.
What is an electrical short?
Because this type of coaxial cable is flexible and easy to work with, it can be used in almost any type of ___________installation.
What is a network?
The__________ the copper core, the farther the cable can carry signals.
What is thicker?
To move packets from source to destination; to provide internetworking.
What is the Network Layer?
The_________of a coaxial cable carries the electronic signals that make up the data.
What is the core?
_____________ is the loss of signal strength that begins to occur as the signal travels farther along a copper cable.
What is attenuation?
_______ manufacturers have agreed upon specific designations for different types of cable.
What is cable?
Thicknet cable can carry a signal for ______ meters (about 1640 feet).
What is 500 meters?
To provide reliable process-to-process message delivery and error recovery.
What is the Transport Layer?
Surrounding the core is a __________ insulating layer that separates it from the wire mesh.
What is a dielectric?
Attenuation causes signals to _____________.
What is deterioration?
_________ is the resistance, measured in ohms, to the alternating current that flows in a wire.
What is impedance?
A __________ connects the thinnet coaxial cable to the larger thicknet coaxial cable.
What is a transceiver?
To establish, manage and terminate sessions.
What is the session layer?
___________ is a signal overflow from the adjacent wire.
What is crosstalk?
Coaxial cabling is a good choice for___________distances and for reliability supporting higher data rates with less sophisticated equipment.
What is longer?
The principal distinguishing feature of the _________ family is the center core of copper.
What is the RG-58 Family?
Both thinnet and thicknet cable use a connection component, know as a _____ connector, to make the connections between the cable and the computers.
