...Shamone Gayles Unit 5 exercise 1: Guided Reading Chapter 10 1. What is the typical organization on an argument essay? Introduction /summary of opposing positions including strengths/ limitations of opposing positions/Your understanding of the issue, describing both strengths and limitations of your position/Reasons your understanding is better than the opposing views’ understanding/ Conclusion 2. What are points of contention, and how do you identify them? My position verses opposing positions, by coming up with the best arguments against your position yourself so you are prepared to counter them. 3. Why is it important to know the stance of your opposition? By knowing your opposition, you can identify the weaknesses in your stance and how to remedy them. 4. What is the difference between argument and research paper? In an argument you pick a topic that is controversial and debatable, whereas in a research paper, you do your research and only report what you find, while not trying to sway in either direction. Chapter 24 1. What is a good way to start the research process? Define your research question and sharpen it/ develop a working thesis that offers your best guess about how you will answer the research question/ devise a research plan to systematically collect the information needed to answer your research question and determine whether you’re working thesis is verifiable. 2. Why is it important to have a sharp research question? Sharper...

...Problems in the World Today Many things can be classified as problems. Individual problems, if significant enough, can be labeled by those who have them as the biggest problem in the world. In truth, most problems in the world are national problems or something that is non tangible and made into a problem because someone thought it needed to be. The only world problem we have, in my opinion, is the expansion of human territory and constant state of war. Many have tried to justify it and many have tried to lessen the blow of its attritions nature but the fact remains that this problem will never go away. Many have hope and promise of a better future without the nations constantly warring but it always gets worse. Why is that? Let’s take a look at the base problems. Too many religions, and when I say too many, I mean thousands upon thousands of beliefs that make as much sense to one another as me believing in some big magic man in the sky who will send me to a hot burning place for all of eternity because I did some semi-bad things once or twice in my 60-80 years of existence. Religion is worse than any sickness and will tear nations apart and spark hatred in the hearts of generations to come. Its easily identifiable and will rally people for the wrong reasons. Should I kill these men of this other country because they wage war on lesser nations for natural resources? Yes, but I’ll tell everyone were doing it for a “holy crusade” and they will feel obligated to join in. Power...

...Intro to Project Management Hector Diaz PM3110 7/23/15 Instructor: Muhammad Bashir Unit 5 Assignment 1; Simulation/Case Study: The Dulhasti Power Plant After reviewing case study 8.1 in unit 5 of the textbook Project Management: Achieving Competitive Advantage (2nd Edition), I was tasked to elaborate on the challenges of delivering an accurate cost estimation when working on harsh geographical conditions. It was observed in the case study that the geographical location chosen for the construction of the Dulhasti Power Plant in the provinces of Jammu and Kashmir, had become too much of a concern for investors and project coordinators, mainly due to a disputed border conflict between India and Pakistan. Not only did the budget increased exponentially over a 20-plus year period (due to the fact that this project was conceived in 1983), but concerns about the local terrorist and nationalist groups in and around the border began to raise numerous questions regarding safety and of course, budgeting (in the sense of hiring extra security to patrol the area). When the Indian government used a fixed-price contract to favor the lowest bids when initially beginning the project, it was believed to be the best method of approach at the...

...Unit 5 Assignment 1: Video Summary NT1110 There are two major manufactures we use in today’s market which are Intel and AMD. There are some minor competitions but don’t stay on the market for long. The system bus for the CPU is also known as the Front-side bus as it inserts the CPU and has a 64 bit data pass. In the CPU theirs a controller that controls communication between the motherboard and other components with the CPU. The ALU is responsible for performing complex calculations. Communications between the controllers and the ALU’s uses a 32 bit wide internal data bus. A processor is usually measured in GHz. A system Bus is usually measured in MHz and has limiting factors of speed. The multiplier is the ratio between processor and the System bus. The system bus speed x multiplier equals the processor speed. CPU manufactures have come up with different ways to make the CPU work faster. Two multi-processing requires multiple processors (In other words your system must be designed to support more than one CPU on a single motherboard). Dual Core Processors have been recently developed, that means incorporating multiple processors with multiple ALU’s inside a CPU. These ALU’s process their information individually. There’s two cache memory’s which are SRAM and DRAM. SRAM is also called Static RAM, it is faster and more expensive then DRAM, it holds memory without being refreshed and DRAM must be refreshed. There are three types of RAM which are L1 cache, L2 cache, and L3 cache...

...internet based attacks. However, in the case of Stuxnet it is generally understood that the worm entered the system via the use of a USB stick. Once on the system the next step was getting the trust of the LAN within the facility, this was achieved through the use of a digital certificate contained in the worm (believed to be stolen from a company called “JMicron” based in Taiwan). Engineered into the worm and proving again how complex and complete the design was when this digital certificate was discovered it instantly replaced it with another digital certificate from another company called “Realtek”. Further investigation found that Realtek was also based in Taiwan, in fact the two companies where in the same industrial park. Figure 1 - How Stuxnet Works [6] An amazing fact with respect to Stuxnet was that it contained four “Zero Day” exploits, a Zero Day is defined in Wikipedia as follows: “A zero-day (or zero-hour or day zero) attack or threat is an attack that exploits a previously unknown vulnerability in a computer application or operating system, one that developers have not had time to address and patch. It is called a "zero-day" because the programmer has had zero days to fix the flaw (in other words, a patch is not available)”. [7] Stuxnet exploited a printer spooler vulnerability, a .LNK vulnerability along with vulnerabilities in the Task Scheduler files and Windows Keyboard file to elevate its privileges to fully control the system. Finally, the worm also...

...The new scoring system has a dramatic change and is potentially game changing, as the scores will escalate by increasing the amount of corners and decreasing the amount of goals. My investigations that are displayed in the tables above have shown all the scores that are possible under 50. Table 1 illustrates all the possible scores if a team were to only get goals; table 2 shows all the possible scores if the teams were only to get corners and table 3 shows all other possible scores of goals and corners. Table 1 demonstrates all the multiples of 8 as each goal represents 8 points and this is the same for table 2 although is all the multiples of 3 that are less than 50. From each of these tables I have found that there are only 9 impossible scores. I gathered that 1,2,4,5,7,10,13,34 and 37 are all scores that are less than 50 and are not possible due to the goals and corners not adding up to these numbers. For example, scoring a corner is 3 points and therefore 1 and 2 are impossible. Another impossible score is 7 as 2 corners=6 and added another corner= 9 so therefore 7 is impossible but 8 is possible as they could score one goal which equals 8. Furthermore, you couldn’t get a score of 4 due to:...

...und the time I come on there are very little staff, sometimes even none, this leads to everyone thinking they can do whatever whenever. You have people spamming, swearing and being racist. I also believe I am on quite a lot so I will be able to keep the server under control when there are no staff and even when there are staff. I believe I can make a difference by being there for people and making sure everyone feels comfortable where they are. This server is good and I don’t want those few people ruining the experience for others. I have been with cyclone network for a long time now and am getting to know everyone. I have a great sense of humour and like getting to know new people, I love the feeling of being welcomed whenever i come on the server everyone says "hi" the community on this server is great! even though im not staff at the moment i still give away advice and help everyone who needs it. Being staff is a step up from that and its not just being helpful its a responsibility. I want to have the responsibility to help others and keep the server a calm and relaxing place to be in. I want to be there even if i am not needed just for the support. If i become staff i will become part of another team, but this teams goal is different, this teams goal is to protect the other team and make sure all of them are enjoying themselves to the max. Our job is to help and make them enjoy themselves, even if that means muting, kicking or even banning another player. i understand that...

...Three factors that need to be considered in a cable installation are fire protection, possibility of water damage and protecting from EMI. Fire protection is very important so that if the building were to catch on fire the coating on the cables would not melt or at least not melt as fast. It is also smart to know where fire extinguishers are in order to possibly prevent the fire from spreading if it is not too large. It is important to consider the possibility of water damage because you do not want your servers and equipment ruined by some water that never should have touched it. In this case it is a good idea to know where water pipes run in the building so that you do not risk placing a network closet underneath a bathroom. Or right night to a bathroom for that matter. The possibility of flooding and ruining server equipment, firewall equipment, and cables by a bursting pipe or overflowing flood is just not worth it. You also want to make sure there are sprinklers but maybe not directly over your servers so that there is a possibility of saving them should they be set off for any reason. Protecting from EMI is very important so that you do not have any breaks in signal or weakened signal experiences. Making sure that your cables run perpendicular to power cables is one way to prevent EMI interference. Another way to prevent EMI is to make sure that you have shielded twisted pair cables instead of unshielded twisted pair cables. There are many things to take into consideration...

...When Erica is presented with manipulatives and asked “How Many?” She is able to state the correct amount for 1, 100% of occurrences, 2, 100% of occurrences, 3, 80% of occurrences. For 4, 63% and for 5, 25%. There are times her attention gets pulled elsewhere causing her to lose the place she was counting. As the numbers get bigger, Erica has a little harder time keeping track of what number she previously hit and what number comes next. There are times when she will hit the button, but it will not work, so she will skip that number or she will touch it again. But she has already moved her finger to the next manipulative, which throws her off. When Erica is asked to identify her numbers in order without any number cards from 1-10, she...

...In the beginning of the lab I started by exploring both the tcpClient.c and tcpServer.c code. When I had a rough understanding of how it worked, I tried running it. This caused an error to occur. The problem was I was using Winsock sockets instead of BSD sockets. One, Winsock, is a socket creator for windows, the other BSD socket is an application programming interface for Unix. So, in order to get the application running, I simply had to change WIN to BSD sockets. Next I ran both files again and this time I got back a message from the server saying that it had received a message. Then I opened Wireshark to view what was going on between the client and server. In the top frame, I could see the handshake occurring between the client and server, the client was sending a SYN(Synchronize) and the Server was replying with a SYN-ACK, which means Synchronize acknowledgment. I also noted there was a push function occurring, and when I clicked on the psh function and viewed its output in the bottom frame of Wireshark, I could see the message that has been sent. Next I learnt about how to run the server I had created infinitely, to do this I put the entire code, starting at the #endif underneath “WSAStartup”, in a while loop. This would cause an issue later on in the lab, which I’ll discuss shortly. After putting in the code, I had to compile it again, and then when I ran it, I was able to continuously create a connection via the client. After that I wanted to have one of my classmates...

...A port expander is a hardware device that will allow users to utilize multiple devices on a single port at the same time. It is the same principle as using a power strip for the power in a home or a splitter for the cable. For example, if you only have 1 Universal Serial Bus (USB) port, yet you have a USB mouse and keyboard, then you can use a USB port expander to allow one port slot to become multiple ports and plug in the mouse and keyboard. Allowing multiple devices to be able to connect to a single port is a major advantage to port expanders. However, one of the biggest drawbacks is that the speed of that port is now divided throughout all the expansion ports, an example being a 3Gbps port expanded to accommodate 4 ports will now have to split that 3Gbps between all 4 ports and not 3Gbps per expansion slot. There are two types of port expanders: internal and external. An internal port expander will usually connect to the motherboard and have an expansion plate with multiple ports along the box of the computer. An external port expander will plug into an existing port (such as a USB) and will then have multiple connections off of the port expander. Port expanders are also very generic and will allow expansion on just about any computer. There are many ports available that come with port expansion hardware. Some examples are, but are not limited to, USB Port Expander Hardware, Microphone Port Expander Hardware, FireWire Port Expander Hardware, Serial Port Expander...

...common clock. In the proposed approach although it is considered that cluster head ( a group leader ) is non-malicious but it may be malicious. A malicious cluster head will not report exact time as which it sends reference packets to all intended receivers, i.e. it will send a false time to all receivers. This false time will be used by group members for synchronisation. Hence all group nodes will synchronise to false time. This can be overcome by fixing the initial sender node as non-malicious. The proposed approach is able to overcome from external as well as internal attacker problems is group synchronisation. The external attacks are resolved with the help of MAC message authentication codes and the use of private keys and the internal attacks is finding out on the basis of send and receive time. Fei et al [8] address water monitoring. It has to be monitored as high chemical levels can cause health problems. The authors propose a scalable, low energy, delay tolerant water quality monitoring sensor network model. It is highly variable, has a long propagation delay and mobile. The time synchronisation mechanism can achieve satisfactory timestamp accuracy.

It uses low cost water sensors and uses multi hop wireless transmissions to relay data until finally reaching surface stations. The tree like routing...
