...Unit 6 Assignment 1: Cable Testers In almost every application in dealing with cable installations, cable testing is a must. Some methods of testing cables include testing for attenuation, continuity testers, DC Resistance, a wire mapper and cable length. In all cable types- copper or fiber, 10BASE-T or 100BASEFX, the standards are constantly being changed and developed into a new standard for all future technologies. When testing cable, you can guarantee that the users will be satisfied when all connections prove effective for not just uninterrupted transmission but correct bandwidths to support. A wire mapper is the most common tool. It simply provides a test of a standard Cat5 cable to ensure each individual wire not only carries a strong signal through the entire length of the route, but it proves if each wire ends up in the correct pin number on the opposite end to receive the transmission. It will give the technician an idea if a cable has a short, or if it is a crossover cable. It is also very useful with telephone connections. It should be a part of each cable installation kit. Another common tool is a continuity tester. It shows if there is a direct connection between two points. If there is a closed electrical pathway for the tester to detect, then the device will make a sound. This is useful not only to test for a short, but also to determine and identify which cable is which in a closet full of many cables. This is also a very important tool in any application...

...interference and degrade network performance. The following paragraphs describe three (3) cable testers and how they work and which cable system(s) they are most suitable for. The first tester is the wire-mapper. Wire-mappers are used primarily with copper twisted-pair cable installations. These devices, according to Oliviero and Woodward (2011, p.422, 441) “Transmit signals through each pair in a twisted-pair cable to determine if it is connected correctly to the correct pin at each end.” The second tool is the tone generator. A tone generator is a two-piece unit that consists of a tone generator and a probe. This type of tester's primary function, amongst installers, is to identify specific locations in a punch-down block then label accordingly. According to Oliviero and Woodward (2011, p.442-443), these testers “Transmit[s] a signal, or, with an alligator clip, you connect the unit to an individual wire. The other unit is an inductive amplifier, which is a pen-like probe that emits an audible tone when touched to the other end of the conductor.” Primary functions are identify a particular cable within a bundle and to test for opens, shorts, and miswires of individual wires. Unfortunately, there is a disadvantage to using this device; time consuming. The third and final tester to be discussed are Multifunction Cable Scanners (commonly referred to as a certification tool). Alarmingly, these devices are highly expensive but are available for both copper and fiber-optic networks...

...Unit 6. Assignment 1. AD User/Group Design Scenario Dear Junior Admin, I received your E-mail and in response I recommend that you do the following. Since there is a domain for each department, such as Marketing, accessing one printer is rather easy. To start off you will need to create a group that allows access to the one printer within each department in your company. After creating each group you must then assign it to a domain local group, global group and then to a universal group. Then you will need to add it to the marketing domain local group. For HR, you will need to take all of the users within the forest and add them to a global then universal group. Proceed to take the universal group and add it to the domain local group within their domain. These users will then have access to whatever is in that universal group, therefore you must make sure that you assign the printer for them to print vacation requests to the HR department. You must take a slightly different approach for R&D. To allow access to only the server, you must first create a domain local group that has some administrative rights. Add them to a customized admins group that you have control of. You can assign these rights and permissions as you create and assign them. Remember to limit their access to their local machines only. You can do all of this through the desktop local user account settings. You may also take a different route if you choose to. This is one of the approaches you may take...

...B. Methodology - B1. Participants or Stakeholders: Because this is an applied research project with a focus on the evaluation of curricular practices, I am the main and active participant. There are an additional three other stakeholders in my proposed capstone research, which includes administrators, students, and the community where I teach. This is because my research will affect these individuals when I get to the application portion of my capstone research. Likewise, two characteristics of my stakeholders relevant to my problem statement include being both supportive and hesitant. First, my stakeholders are supportive. I have felt very supported as the art educator in my school district by administration, students, and the community. This is relevant to the problem statement in Part A because I know I have the support to create curriculum in my classroom. I know that if I asked for resources or help with my curriculum, that it would be provided. Second, my stakeholders are also hesitant. I believe that they would be hesitant specifically to make a change in my curriculum. This goes back to my problem statement because I am responsible for the curriculum I create. This means that if I decide to change the curriculum currently in place at my school, I believe there will be hesitancy with administration, students, and the community. While these stakeholders support me, change can be scary for some individuals. I believe there is an expectation from these individuals to continue...

...Scenario 6 Additionally, in order to calculate the probability that exactly 1 marriage will be in the stock, one would apply the same formula as before. Since the stock is composed only of three cards, there could only be 1 marriage. There are 22 possible cards to receive (n) which are not a marriage since there can only be 1 other card (r). It doesn't matter whether the other card would be a pair card or not since it couldn't be a marriage by itself. There are four diverse marriages which means there could be four various marriages with 1 different card from the 22 other cards. This probability is extraordinarily low. It's the lowest probability of all. From my personal experience playing this game, it seems to be true, however, in an actual game the fact that players get cards one by one and not in a row, alters the probability and decreases it even more. The probability of getting exactly 1 marriage in the stock is exceedingly low itself. Rarely does it happen, that there is a pair in the stock which supports this calculation....

...Problem Statement For this problem we are trying to find how many rebounds and corners it will take the ball to go into a pocket. We are also trying to find out what pocket the ball will land in,and if there are any patterns that meet that criteria. The rules include that you have to start at the lower left corner , and at a 45 degree angle. Also you have to start with whole number dimensions(4 by4 , 2 by 3), and there is only 4 pockets on the pool table. Process We had each member of our group draw out the pool table and try different whole number dimensions . Afterwards , we looked at each of our examples and charts and compared them to make a bigger chart with all the dimensions of 1-4 . We did this just to figure out if there were any common patterns within the the pictures and tables. Making a super pool table and coming up with our own patterns within the dimensions and rebounds was something we also did, by doing this we got to see if one of our patterns can match a bigger size dimension pool table along with the other dimensions. In conclusion we made a mini poster explaining our thoughts about this problem, within this project we got to go around to see what our classmates also had in mind. Solution...
