Why are standards so important for NICs, connectors, and media Essay Example for Free

Why are standards so important for NICs, connectors, and media EssayUse your textbook and meshwork research to rationalise your answer. Standards are put in place to make everything work together error free. Because Stability, Consistency, Minimization of packet errors.4.1.2The 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 electrical energy on the copper wire is so high? Use your textbook and Internet research to support your answer. Because the voltage used to transmit data needs sole(prenominal) be high enough 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. Hospit als, security systems, PA recording studios. The drawback of STP pedigrees is that they provide increase the total cost of an installation. STP airs are more expensive due to the shielding, which is an additional material that goes into every meter of the c equal. The shielding also makes the cable heavier and stiffer. Thus, it is more difficult to handle.4.1.4Complete 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 networking is the Registered seaman 45 ( RJ- 45) interface. This uses eight copper wires ( four twisted pairs) to complete the connection between interfaces. The pinout for these wires defines the order in which the individual wires connect to the network interface notice and how the wires transition from one end of the cable to the other. A straight cable is used to connect a device to a network hub or switch. This lineament of cable does not change the wir ing order from one end to the other. You can see an example ofthis in Figure4- 1.Cat 310MbpsToken/10 human foot TCat 416MbpsTokenCat 5100MbpsEthernet/TokenCat 61000MbpsGigabit EthernetCat 6a1GbpsGigabit Ethernet4.1.5Another computer. Using Figure 4- 1 and Table 4- 2 as an example, create the plat 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 evidently 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 coaxial cable from the inside(a) core to the outer insulation. Use your textbook and Internet research to compose your answer. Coaxial cable consists of a core of copper wire surrounded by insulation, a braided metal 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 your te xtbook and Internet research to dislodge your answer. 100 meters a signal 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 links 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. disembodied spirit 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 LAN system term domain reflectometer is an electronic instrument used to characterize and locate faults in metallic cablesa.
