There are nearly as many WAN categories as there are LAN choices. A very simple WAN is nothing more than two PCs calling each other over a modem connection. A more complex WAN may involve connecting hundreds of organizations together with high-capacity digital circuits. Usually a WAN takes the form of something between these extremes.

What expansion of network services and benefits might the library achieve?
I personally believe the library can accomplish more free will in offering the Wi-Fi for its supporters. Which is done by going with a wireless operation ads opposed to a tough line makes sense from a theoretical point.

What LAN protocol and related transmission speed are most appropriate for the local libraries: Ethernet, fast Ethernet, or gigabit Ethernet?

From my research I came to the understanding that the Ethernet protocol documents can be transmitted over wireless admission points, twisted pair, coaxial, or backbone optic cable at a speed of 10 Mbps up to 1000 Mbps. Also, Fast Ethernet obligates the use of diverse, more exclusive network concentrators and network boundary cards. Fast Ethernet is becoming mutual in schools that have been wired lately.

What topology is most appropriate for the LANs and the WAN? What are their merits?

In this particular case Hubs or switches can be attached to one another to produce greater LANs capable of supportive devices. When this comes to a completion, you began getting some stimulating hybrid topologies. The greatest hybrid topology has arrived with the introduction of wireless technology.

Explain the elements of the backbone.

The term backbone refers to the cable used to connect a main or intermediate cross-connect to a telecommunications closet. However, networking locations, a backbone,

...Discussion Board Unit 4 Busn105/1304 Discussion Board Unit 4 Two Challenges that Companies Face in Ethics One of the challenges is the company’s employees. Employees sometimes don’t follow the company’s policies. This issue can be a problem in so many ways. If employees are not following the rules it can reflect on the companies’ credibility. Bad credibility can cause sale loss and the company can lose their credentials. Another issue is the companies themselves. Changes within the company and communication with the employees can interfere. If Companies don’t have all the information and they pass it to the employees it can cause an impact on the ability of the employees to do their jobs. It is very important to make the proper changes so that there aren’t conflicts within the company. Two Challenges in the Area of Social Responsibility Resource investments can be an obstacle for business owners. Convincing investors or shareholders the company is worth investing in. Companies have to educate the shareholders and explain why they would benefit from investing. Another challenge is being successful in programs within the company. Programs that flop can cause company crisis and can result in damaging the company’s reputation. What is Management’s Responsibility in Addressing These Issues? Management has the responsibility to deal with these issues in a professional manner. Researching every aspect of the issues and deciding what would be more beneficial...

Acct311 Unit 4 Discussion Board

...The Discussion Board (DB) is part of the core of online learning. Classroom discussion in an online environment requires the active participation of students and the instructor to create robust interaction and dialogue. Every student is expected to create an original response to the open-ended DB question as well as engage in dialogue by responding to posts created by others throughout the week. At the end of each unit, DB participation will be assessed based on both level of engagement and the quality of the contribution to the discussion. At a minimum, each student will be expected to post an original and thoughtful response to the DB question and contribute to the weekly dialogue by responding to at least two other posts from students. The first contribution must be posted before midnight (Central Time) on Wednesday of each week. Two additional responses are required after Wednesday of each week. Students are highly encouraged to engage on the Discussion Board early and often, as that is the primary way the university tracks class attendance and participation. The purpose of the Discussion Board is to allow students to learn through sharing ideas and experiences as they relate to course content and the DB question. Because it is not possible to engage in two-way dialogue after a conversation has ended, no posts to the DB will be accepted after the end of each unit. Consider the following scenario: Lucy Shafer wants to borrow $100,000 to expand her dog-breeding...

...Grade Received, "A" Information systems will definitely alter the way that healthcare organizations are structured. Information systems were made to aide a business in having an aggressive lead over competition by giving support and helping to shape the makeup and strategies of the business. Upgrades to information technologies have raised the productiveness of healthcare services as well as employees because an advance in technology lowers the usage of paper records. These alterations in technology enable data to be distributed and reserved in exceptional ways, enabling information to be traced, evaluated, and exhausted in a manner that aides in delivering more competent care. Due to the type of data that is attainable via healthcare information systems, the makeup of the healthcare business will conform in consensus to the pertinent information systems. These systems will not only affect direct-care services like doctors and nurses, but will also alter non direct-care fields like analysis and growth, invoices, medical records, and more (Fottler, Ford, & Heaton, 2010). Fundamental alterations due to information systems are inescapable because of the alterations in how the data is acquired, reserved, and fetched. Information systems are intended to reply to inquiries. Nurses might exhaust upgraded systems to keep track of patients’ vitals; thus, altering the method of how care is given as well as the effectiveness of responses to the failing health of hospitalized consumers...

...the drawn out mathematical analysis. "Quantitative research methods are the best!" “Quantitative research tends to focus on specific behaviors that can be easily quantified” (Cozby and Bates, p. 115, 2012). Quantitative research draws it conclusions based off of the statistical analysis of data. Therefore, the results are in numerical form and then analyzed using statistics. Qualitative research cannot be converted to numerical form so the results cannot be analyzed using statistics. I find that this is the best method for research because it proves that there is a truth in things. Unlike quantitative research which is subjective. An example of how quantitative research shows the truth: The movie was awful is qualitative. The movie lasted 4 hours is...

...Athletes and performance-enhancing drugs Randy Orton (Harris, 2012), Mark McGwire (ESPN, 2014), Chris Benoit (Mongomery, 2007), and even Lance Armstrong (Wilson, 2013) -- what do these four athletes, to name a few, have in common? These athletes made headlines in recent years admitting to drug usage, including drugs that increase performance. When it does come to use of performance enhancing drugs, expect nothing but potholes and detours on your road to success. The one thing that is highly questionable to me is whether or not there are any drugs that can detoxify athletes in a way that buprenorphrine would treat at least the side effects of heroin (NYC Department of Health) like we talked about recently. There are four articles on four different athletes I pulled up that should be able to solve majority of these questions explained here. According to another recent article, drugs were clearly involved in Chris Benoit's double-murder suicide. (Sutton, 2007) What Benoit did was a little bit too graphic for me to explain here and I would rather not go too far into detail. I would personally say that I had seen many physical reactions to drugs. I can only recall as a young boy, aged 6/7, where a boy went out of control and had to get 5 adults to drag him into a time-out room. I asked my teacher at the time if he might have had one pill too many, jokingly, but it seemed confidential. I believe that any psychological reaction to these drugs would have the consumer...
