Question 1

Divide the channel into multiple intervals of time or timeslots. These timeslots are reserved for their designated knows regardless of whether that node as data to transmit

Answer 1

Time division multiplexing or TDM

Question 2

Assigns timeslots to notes but it then adjust the slots according to priority and need this approach uses all swatch rather than leaving some unused which provides improved efficiency in using available been with on a net work. Still this does not allow multiple signals on a wine at the exact same time

Answer 2

Statistical time division multiplexing

Question 3

This assigns different frequencies to create multiple frequency bands each use by a sub channel so that multiple signals can transmit on the line at one time she does a modulator into different frequencies than multiplex to simultaneously travel over a single channel and the multiplex at the other end

Answer 3

Frequency division multiplexing FDM

Question 4

Works with any fiber optic cable to carry multiple signals simultaneously by dividing a leaping into different wave links or colors on a single fiber technology were similar to have a prism spreads white light into first colors

Answer 4

Wavelength division multiplexing WDM

Question 5

Increases the number of channels provided by normal WDM to between 80 and 320 channels tense version of this can be able to find any roots and is typically used on high been with for a long distance

Answer 5

Dense wavelength division multiplexing or DWDM

Question 6

Lowers caused by spacing frequency bands wider part to allow for cheaper transceiver equipment

Answer 6

Course weather in division multiplexing or CW DM

Question 7

This was the foundation of Ethernet networks in the 1980s you’re most likely never see these cables for network for computers as they’ve been replaced by Newark mediatize however a form of these cables is still use for cable Internet cable TV and some multimedia types

Answer 7

Coaxial cables

Question 8

This cable have a central Metalcore surrounded by an insulator a Braden metal shielding an outer cover called her she’s

Answer 8

Coaxial cable

Question 9

A measure of the opposition to eat currents flow through a cable has expressed in ohms

Answer 9

Impedance

Question 10

What are the two main coaxial cable specifications

Answer 10

RG 59 and RG six

Question 11

Braided copper core, 20 or 22 AWG core, still use and relatively short connections is less expensive than the more common RG six but suffers from greater attenuation

Answer 11

RG 59

Question 12

Solid copper core, 18 AWG conducting core, used to deliver broadband cable Internet service and cable TV particularly in the last stretch to the consumers location

Answer 12

RG six

Question 13

Disconnector attaches to coaxial cable so that the core of the center of the cable extends into the center of the connector

Answer 13

F connector

Question 14

This connector is crimped compressed or twisted want to be coaxial cable it’s it’s name is a term that refers to both the oldest child connection and it’s two inventors

Answer 14

BNC connector

Question 15

Looks very similar to coax cable except that there are two course or conductors inside the cable to Corus cooperate and a half duplex fashion to transmit data and so that it is capable of supporting much higher throughput then coax

Answer 15

Twinaxial cable
