One of the biggest disadvantages is not being able to make connections as easy as the copper. Fiber optic cables have a core as fine as a human hair, making it extremely difficult to splice. Copper cables are obviously not going to be around forever with the fiber optics being so futuristic, but they still have advantages over the fiber. Copper is very easy to work with. When making connections it is so much easier to splice the copper cable than it would be for the fiber.
Lydell Smith NT1310 Unit4 assignment 1 copper vs. fiber In this paper I will discussed two different cabling copper and fiber cabling. I will contrast both cabling types show strengths and there weaknesses, also what situations you would choose one over the other. Copper and fiber optic wiring are the two most common and widely used cabling types today for the means of communication all over the world. Both have the same basic concept to transmit information from point A to point B but both have their strengths and weaknesses and therefore, a person installing cabling may be reluctant to choose one over the other. Copper cabling is the less expensive of the two to install.
Fiber Advantages The following advantages of fiber over other cabling systems are: (Oliviero 250) Immunity to electromagnetic interference (EMI), higher data rates, longer maximum distances, and better security. With copper cabling there is one common cabling problem they are susceptible to EMI. EMI is a stray electromagnetism that interferes with the signal. All electrical cables generate a magnetic field around their central axis. If you pass a metal conductor through a magnetic field an electrical field is generated in that conductor.
Exercise 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.
Hydroelectricity is the production of power through use of the gravitational force of falling water or flowing water. Lastly solar energy is using the suns energy to produce electricity. Solar energy is one the fastest growing energy sources and new technologies are developing at a rapid pace. The main thing about all this there sources of energy is that they are environmental friendly, and their maintenance is low cost if compared with other sources of energy. Why using wind power, solar energy, and hydroelectricity?
Already in place, can be very cheap to use | Coaxial | Television cable | Must run cable to all locations, can carry much higher speeds than Telco. Is a little more expensive to run. Needs boosters at specific distances | Fiber-optic | Glass cables with POP’s at specific distances | Uses a customized infrastructure to run dedicated connections: this is a costly option | Electric power lines | Power lines. They are everywhere and the infrastructure is already there | This type of media can be used with Broadband over Power Lines (BPL), making use of the extensive infrastructure in place already | Table 7-2 WAN Wireless Media Media | Summary | Satellite | Not very fast, has a delay of about 1 second, very costly to use. Uses a star topology | Imax (Worldwide Interoperability for Microwave Access) | This has 75Mbps speeds and can transmit for distances up to 30 miles.
The main issues with having only a 56K dial-up modem is the modem is not always on and with a broadband/T1 connection, there won’t be any down time when trying to communicate with another store. POS Components operate better on faster and more up to date equipment. The technology is outdated and to maximize work efforts the company needs a faster data transfer rate and up to date information. This can only be achieved with the proper network solution. A new WAN (Wide Area Network) will be replacing the current setup and each site will have a wireless LAN (Local Area Network) as well.
A signal from the source travels in both directions to all machines connected on the bus cable until it finds the intended recipient. If the machine address does not match the intended address for the data, the machine ignores the data. Alternatively, if the data matches the machine address, the data is accepted. Since the bus topology consists of only one wire, it is rather inexpensive to implement when compared to other topologies. However, the low cost of implementing the technology is offset by the high cost of managing the network.
For example, when I am both at home and at my workplace, we usually use power saving and energy efficient light-bulbs which do not consume such high amounts of energy compared to other sources. Another example would be regarding my vehicle (however, this can be viewed from multiple perspectives). Instead of using fuel to power up my vehicle, I would use an electrical vehicle which would not pollute the environment, but it would have to consume electricity to be charged. Anyway, research is still undergoing in this field. I can do conservation of energy when it comes to heat energy by only powering up the heat system when needed, and not wasting heat energy.
According to Rod Blagojevich, former governor of the state of Illinois, “Wind is the country’s fastest growing source of energy, and I would like to see Illinois generate 3,000 megawatts of electricity from the wind (equivalent to three nuclear power plants) by 2012,” (Manor, pg.# 2). As near-sighted as this goal and Blagojevich’s political career turned out to be, it was not feasible, but many wind specialist agree that this amount of energy and perhaps even more can be generated by wind turbines as soon as the year 2030. There are a few factors to consider when determining where to place a wind farm and they’re not something that can just be slammed together overnight. The cost of constructing an entire wind farm can run into the billions of dollars, and with the U.S. being in a state of financial crisis, finding the funding for such projects can be a substantial task in itself. Factoring the
