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

Why are standards so important for NICs, connectors, and media Essay Use your textbook and Internet research to justify your answer. Standards are put in place to make everything work together error free. Because Stability, Consistency, Minimization of packet errors. 4.1.2 The 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. Because the voltage used to transmit data needs only be high enough for the receiver to detect it. Making the voltage higher would make the receiver electronics more difficult. 4.1.3 The 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. Hospitals, security systems, PA recording studios. The drawback of STP cables is that they will increase the total cost of an installation. STP cables are more expensive due 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 Complete 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 Jack 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 card 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 type of cable does not change the wiring order from one end to the other. You can see an example of  this in Figure 4- 1. Cat 310MbpsToken/10 base T Cat 416MbpsToken Cat 5100MbpsEthernet/Token Cat 61000MbpsGigabit Ethernet Cat 6a1GbpsGigabit Ethernet 4.1.5 Another 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. 4.1.6 Briefly describe the layered construction of a coaxial cable from the inner 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. 4.1.7 Based solely on the distance limitation of UTP cable, what should you guarantee about any network you plan for UTP cable? Use your textbook and Internet research to justify your answer. 100 meters a signal repeater 4.1.8 What 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 UTP 4.1.9 If 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 and  Internet research to justify your answer. 4.1.10 Briefly 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 LAN system Time domain reflectometer is an electronic instrument used to characterize and locate faults in metallic cablesa.
