Why are standards so important for NICs, connectors, and media Essay Example for Free
Why be standards so important for NICs, connectors, and media Essay affair your textbook and internet look to justify your answer. Standards are put in place to make everything work together misunderstanding free. Because Stability, Consistency, Minimization of packet errors.4.1.2The voltage for registering a bit of 1 on Ethernet place be as low as 2.5 volts or flat 1 volt. Why is this so low when the capacity for contagion electricity on the copper electrify is so high? Use your textbook and internet inquiry to support your answer. Because the voltage used to transmit data needs only be high abounding for the receiver to detect it. Making the voltage higher would make the receiver electronics more difficult.4.1.3The voltage for registering a bit of 1 on Ethernet can be as low as 2.5 volts or even 1 volt. Why is this so low when the capacity for transmitting electricity on the copper wire is so high? Use your textbook and Internet research to support your answer. Hosp itals, security systems, PA enter studios. The drawback of STP cables is that they will increase the total cost of an installation. STP cables are more expensive overdue to the shielding, which is an additional material that goes into every meter of the cable. The shielding also makes the cable heavier and stiffer. Thus, it is more difficult to handle.4.1.4 get laid the entries in Table 4- 1. Use your textbook and Internet research to compose your answer. The common connector for interfacing UTP wires to a computer for electronic vaneing is the Registered Jack 45 ( RJ- 45) interface. This uses eight copper wires ( four twisted pairs) to complete the connection amidst interfaces. The pinout for these wires defines the order in which the individual wires connect to the network interface card and how the wires transition from one wind up of the cable to the other. A right away cable is used to connect a device to a network hub or switch. This type of cable does not change the wi ring order from one end to the other. You can see an example ofthis in Figure4- 1. goofball 310MbpsToken/10 base TCat 416MbpsTokenCat 5100MbpsEthernet/TokenCat 61000MbpsGigabit EthernetCat 6a1GbpsGigabit Ethernet4.1.5Another computer. Using Figure 4- 1 and Table 4- 2 as an example, create the diagram and color coding for a crossover cable. Use your textbook and Internet research to compose your answer. Hint The crossover cable is more complex than simply reversing the entire set of wires. You are wiring the input pins to the output pins and vice versa.4.1.6Briefly describe the layered construction of a concentrical cable from the inner core to the outer insulation. Use your textbook and Internet research to compose your answer. concentric cable consists of a core of copper wire surrounded by insulation, a braided alloy shielding, and an outer cover.4.1.7Based solely on the distance limitation of UTP cable, what should you guarantee about any network you plan for UTP cable? Use yo ur textbook and Internet research to justify your answer. 100 meters a quest repeater4.1.8What type of cable is necessary for each connection in Figure 4- 2 straight or crossover? You can assume that S1 and S2 do not have the ability to resolve crossovers ( called Auto- MDIX). Use your textbook and Internet research to compose your answer. They both need straight UTP4.1.9If all the connections in the network from Figure 4- 2 use UTP cable, will they all be able to communicate correctly? If not, which cerebrate will not function and what should be done to resolve the issue? Use your textbook andInternet research to justify your answer.4.1.10Briefly describe the purpose of each of the following network testing devices Multimeter- an electronic measuring instrument that combines several measurement functions in one unit. Tone generator-electronic audio acoustics and equipment testing and setup, or informational signals, commonly associated with a telephone system Pair scanner- used to locate problems in a local area network systemTime domain reflectometer is an electronic instrument used to characterize and locate faults in antimonial cablesa.
