4.1.1
Why are standards so important for NICs, connectors, and media? 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
