Courtney Patin Week 1 Telecommunications Exercise

1) Local Loop
a. The local loop is the physical wiring that connects you to the public switched telephone network (PSTN). This line can be a voice line, or it can be a data line. The physical wiring for the local loop consists of a pair of twisted copper wires that run from the telephone company's central office (CO) to the subscriber’s premise and another pair of twisted copper wires that run back to the telephone company’s CO.
2) Central Office
a. In telephone communication in the United States, a central office (CO) is an office in a locality to which subscriber home and business lines are connected on what is called local loop. The central office has switching equipment that can switch calls locally or to long-distance carrier phone offices. In other countries, the term public exchanges is used.
3) Local Exchanges
a. A local exchange carrier (LEC) is the term used in the U.S. for describing the telephone company which operates within a local area and provides telecommunication services within that area.
a.i. Local exchange carriers started across the U.S. following the breakup of the Bell system due to antitrust regulations. Local exchange carriers are allowed only to handle local calls, and not any long-distance traffic.
4) POP
a. Point of presence (POP) is the point at which two or more different networks or communication devices build a connection with each other. POP mainly refers to an access point, location or facility that connects to and helps other devices establish a connection with the Internet.

...My hypothetical company is a small online gaming company called Game Zone. Seeing as how this is an online company, backing up of data and applications is crucial. The follow is the backup plan I would suggest. * The company should back up all online users profiles and gaming applications. I would also suggest redundant servers. * The rotation should be done every day due to the constant change of user profiles and the fact that new material is always being added to keep games up to date. Full backups should be done weekly with differential backups done daily. The full backup should be done at the start of every week at the lowest peak of online use and the next 6 days done with differential. * Seeing how this data is the life blood of the company it should be taken offsite daily. * If data on the current server is lost only that day’s activities is lost. * If they have redundant servers then down time will be minimal depending on configuration, minutes. If all servers lose their data then recover time may exceed hours. There is no paper trail to recover non-backed up data as all information is online. * Since the company exists only online restore time would be long due to the need to reload all gaming apps and user profiles. Contingency plan must be drawn up for all possibilities. Compile a list of all eventualities then create procedures to recover the data. All procedures are to be tested to make sure they work. * Data should......

Provide a brief explanation with each example. Refer to Ch. 1 in the text for explanations of these dimensions. Physical health: Exercise at least five days a week. Physical fitness has to be up to par to stay in the military. I usually watch my diet because I am not as young as I use to be. Social health: Right now I really do not have a social life. It might not be healthy but I guess I do it to protect myself. Having to move around a lot does not allow me to build the friendships that I am looking for. Intellectual health: Being in the military sometimes requires critical thinking to complete a mission. Many times it’s accomplishing a mission that you have already done. I usually refer back to those past missions and put together the pieces that I need to accomplish the new one. I take to account failures and successes of my past missions and use it for the current one. I also take in to account other people’s failures and successes. Environmental health: I try to surround myself with people I can learn from. At the beginning of my career I use to hang out with soldiers who were not looking to approve themselves and just got into trouble. Once my son was born, I knew the life had to change.

Nt Unit 6 Assignment 1

...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......

GNU stands for "GNU'S Not Unix", and it was designed to be a UNIX-like operating system developed by Richard Stallman. Linux is the name of operating system kernel developed by Linus Torvalds. GNU's tools aside the Linux kernel make the operating system known as “Linux” aka “GNU/Linux”. Thousands of people helped refine the operating system online. Chapter 2 1. Briefly, what does the process of installing an operating system such as Fedora/RHEL involve? Installing Fedora/RHEL is the process of copying operating system files from a CD, DVD, or USB flash drive to hard disk(s) on a system and setting up configuration files so Linux runs properly on the hardware. Several types of installations are possible, including fresh installations, upgrades from older releases of Fedora/RHEL, and dual-boot installations Chapter 3......

...Week 1 Assignment 1 Michael Conley ITT Technical Institute Abstract This paper will be identifying, analyzing, and explaining five likely threat/vulnerabilities for the scenario given. I will go into detail on what you should do to lower the risk or vulnerability. The last thing I will talk about in this paper is what you should do to try and make it better and more secure. There are definitely some potential risks and vulnerabilities with the given scenario. The first one to point out would be that they are using Windows Vista. Another issue is the VPN connection with the laptops. Issue number three would be the servers. The fourth problem I foresee is back up. The final problem I see in the network is with the ISP. This is not a very old and outdated OS, since Microsoft is still supporting it, but there are more vulnerabilities with using Vista as opposed to Windows 7. Windows 7 is also more versatile, it is able to be run on more than just desktops unlike Vista. Windows 7 is able to be used on laptops, desktops, and netbooks which Vista cannot be used on all of those. Windows 7 puts all of the security notifications and other system problems in one place unlike Vista where you have to search through the control panel to find things. Windows 7 you just go to the action center. The likelihood of there being a serious security issue with windows Vista is low for right now.......
