...UNIT 4. Assignment 1. Copper vs Fiber As the name suggests, fibre optic technology uses pulses of light to carry data along strands of glass or plastic. It's the technology of choice for the government's National Broadband Network (NBN), which promises to deliver speeds of at least 100Mbps. When we're talking about 'speed' were actually talking about throughput (or capacity) — the amount of data you can transfer per unit time. And fiber optics can definitely transfer more data at higher throughput over longer distances than copper wire. For example, a local area network using modern copper lines can carry 3000 telephone calls all at once, while a similar system using fiber optics can carry over 31,000. So what gives it the technical edge over copper wires? Traditional copper wires transmit electrical currents, while fiber optic technology sends pulses of light generated by a light emitting diode or laser along optical fibers. In both cases you're detecting changes in energy, and that's how you encode data. With copper wires you're looking at changes in the electromagnetic field, the intensity of that field and perhaps the phase of the wave being sent down a wire. With fiber optics, a transmitter converts electronic information into pulses of light — a pulse equates to a one, while no pulse is zero. When the signal reaches the other end, an optical receiver converts the light signal back into electronic information, the throughput of the data is determined by the frequency......

...Motherboards Marc Burzynski Unit 4 Assignment 1 NT1110 07/20/2013 Video 1.04 Summary This video talked about the differences in the different form factors motherboards as well as the similarities. It explains for those of us who prefer to build our own systems that we should select our motherboard before buying the tower and after we have selected the CPU. It also explains about the different types of connectors found on motherboards. List Of Topics, Terms And Definitions * Motherboard – The most important consideration, the size and shape is determined by form factor * ATX Form Factor – Replaced the AT form factor, ATX is smaller, easier to work on, better organization, has support for a wide variety of I/O devices, usually has is the P1 20 pin or 24 pin power connector, on the older ATX form factor motherboards were connected via the PS/2 connector at the back of the case, the newer ATX form factor motherboards connected keyboard and mouse via a USB, usually has between two and four DIMM slots, has either PCI E Oren AGP slot but not both, usually has 2 40 pin IDE slots, and usually 1 to 2 serial ATA slots. The ATA form factor was the first to introduce the soft power switch on the front of the computer; the soft power switch does not immediately cut power but instead allows the computer to go through the normal shutdown procedure. There is however a power switch on the back of the computer, flipping the switch immediately kills power. Another......

...even buy a case because sometimes the motherboard will not fit into the case. There are three form factors today. Atx which replaced older AT Motherboards. They are also easier to work on. ATX also has a soft power switch on the front of the computer and a power switch on the back. The second form is the BTX form. This has better air flow for cooling by having an intake vent on the front of the computer and an exhaust vent on the back. The last is an NLX form used on low end computers and is also known as daughter boards. On the bottom of the motherboard there are numerous copper traces know as Buses. A motherboard will have expansion slots. It will have either several PCi slots and one AGP slot or several PCI slots and one PCIe slot. 3 &4.

...Jake Robinson ET3220 Unit 4 Assignment 1: Unit Review Questions 6.2 The function of a modem is modulation and demodulation. A modem takes a signal and modulates it so that the data can be sent via an audio link such as a phone. Then at the other end of the line another modem demodulates the signal back into the original data that was to be sent. 6.3 Three major advantages of digital transmission over analog transmission are: 1. Digital transmissions cannot get corrupted by noise. 2. Digital signals typically use less bandwidth. 3. Digital transmissions can be encrypted so that only the intended recipient can decode it. 6.4 In ASK or amplitude-shift keying the two binary values are represented by two different amplitudes of the carrier frequency. The limitations of ASK are that it is linear and sensitive to atmospheric noise, distortion, propagation condition on different routes in PSTN. It requires extensive bandwidth and is therefore a waste of power. 6.7 QAM is a popular analog signaling technique that is known as quadrature amplitude modulation. This modulation technique is a combination of ASK and PSK. QAM can also be considered a logical extension of QPSK. QAM takes advantage of the fact that it is possible to send two different signals simultaneously on the same carrier frequency, by using two copies of the carrier frequency, one shifted by 90 degrees with respect to the other. 6.8 The sampling theorem tells us that the......

...NT1330 Unit 4 Assignment 1. AD Design Replication Scenario AD Design Replication Scenario To whom it may concern: I am the IT Administrator for the company and I have been asked to give my recommendations for the Active Directory Replication Design of the two new Branches. The first I can recommend for you is that all the information that is needed for each new site is correctly documented and added to the Root Active Directory through the Active Directory sites and services. This is done because the Root AD automatically builds the inter-site replication topology based on the information provided about the new site connections. Each new site’s AD will have one each domain controller that is known as the inter-site topology generator and they are assigned to build the topology at their sites. To add two new branch offices we will need to find a strategy to design a replication process. To implement this we will need to use inter-site replication. Inter-site replication is needed when adding domain controllers located in different sites. We will also need a site link (Site link is a logical, transitive connection between two sites that allows replication to occur) protocol of Remote Procedure Call (RPC) over Internet Protocol (IP) which is the preferred choice for the replication process. This allows you to communicate with network services on various computers and also keep data secure when being transmitted by using both encryption and......

For each device we have we would also have to have a router that was made by the same company and so on. There would be a big impact on our personal and business communications because of them not working across a wide variety of devices combined. Exercise 3.1.2 An example of a model for something that is difficult to perceive is a movie based on a book. A movie can provide visuals for someone who struggles to image events of a book in their head. By using picture and sound a movie is much easier to understand than a book for some or most people.

...1 Running head: UNIT 4 ASSIGNMENT 1 Fundamentals of Finance BUS 3062 Rodtrice Johnson 3/7/16 Unit 4 Assignment 1 Dennis Hart 1. Q: Proficient-level: "How do Cornett, Adair, and Nofsinger define risk in the M: Finance textbook and how is it measured?" (Cornett, Adair, & Nofsinger, 2016). Distinguished-level: Describe the risk relationship between stocks, bonds, and T-bills, using the standard deviation of returns as the measure of risk. Answer Proficient-level: Risk is defined as the volatility of an asset’s returns over time. Specifically, the standard deviation of returns is used to measure risk. This computation measures the deviation from the average return. The idea is to use standard deviation, a measure of volatility of past returns to proxy for how variable returns are expected to be in the future. Answer Distinguished-level: Stocks and bonds have very different risk-return characteristics. In general, while stocks are more volatile than bonds, over the long run, stocks are expected to yield higher returns than bonds. By varying the mix of stocks and bonds in a portfolio, an investor can achieve her desired level of risk exposure. However, the level of risk in a portfolio depends not only on the risks of individual assets, but also on the movements of the individual assets in the portfolio. 2.
