The access network is the part of the network that connects the individual consumer or business to the telecommunications system.

I thought of the English Army, and hoped for their coming, and being taken by them”(Perkins, 83). Mary had seen the Natives in a very vulnerable level compared to that of the other authors who were ether in a situation of power or instance of the same position of strength. Mary is going to have a negative attitude because of her village being attacked and her being taken hostage. Cotton Mather had a lot of the same views as the Indians with strong religious followings. “Mather himself has been viewed as a pedantic egotist, a reactionary, and a bigoted witch-hunter; yet it seems only just to remember also that he was fighting a losing battle for the survival of an ideal”(Perkins,109). Then there is the most compare able of the three to todays age and that is John Smith looked at them unlike the other to and that was more as equals.

Once it has been decided which operating system will be implemented, the task at hand will be to upgrade each machine to the new operating system. Any updates as well as any firmware that needs to be installed will also be done during this stage. In addition, the desktops at the employees’ homes will also need to have the operating system upgraded.

These users should be assigned their own special permissions so that they have access to the resources needed to perform their job. Those laptops that are to be used in the field will need to be configured so that they are able to access the network remotely. One of the issues that needs to be addressed with this is security.

...University Of Phoenix Demonstrative Communication By Patrick Nwosu What is Communication? Communication is the process in which information is passed between individuals through a common system as defined by merriam-webster dictionary. When I think of communication, I am reminded of the Abbott and Costello routine “Who’s on First”. The comedy routine is a perfect example of how things can go wrong if the message is not properly encoded or decoded. Communication can happen either in a positive or negative manner. While watching the skit, the transformation from positive to negative communication is evident. “Who’s on First” is the perfect example of demonstrative communication with all the body language and most of all the tone of voice that happens during the conversation. Communication starts with the sender who will format the message content, how to deliver it and make sure that the message is clear. The message needs to be coherent so it can be understood by the receiver. This is an important step made by the sender in ensure effective communication through the use of non verbal ways. The sender will need to make sure to use the proper grammar, tone of voice, and gestures that fit with the context of the message. Demonstrative communication uses body language, tone of voice, facial features, gestures, and any other forms of non verbal interactions.

According to our website we see and treat nearly 41,000 children per year in the ED (“Cardinal Glennon”, 2015). It is truly a fascinating place to work and I learn something new every day that I am there. How Statistics are used at my Workplace: At Cardinal Glennon, there are various forms of statistics used. Like many other hospitals, the administration keeps track of numbers for all sorts of reasons. A few examples are as follows; the amount of infections that are related to central lines, how much profit was made each year, how many patients were seen in the ED each day, week, month and year, patient satisfaction scores, handwashing rates of co-workers, amount of blood cultures drawn each month and the amount that were determined contaminated. Those are just a few that matter to nursing but I am sure each individual department has their own forms of statistics they track. After these different sets of data are complied, some form of chart or graph is used to make an impact on the employees. This helps show the real data and make it easier for us to see just how much the numbers change each month. Of course an action plan is then formed to help us be able to “better” our numbers to reflect better or more cautious care. These charts and graphs can be an eye opener for the nurses a lot of times.

Establishing this policy will protect the company and employees against attacks that may cost them tons of money and even their jobs. The policy will define several different security practices that employees need to adhere to in order to keep the network safe. These policies will be dictated through an AUP and signed by all employees with access to the network. The employees will also have to go through initial information security training before gaining access to the network. This training will also be required annually in order to maintain their access to the network. The AUP will dictate the requirements for passwords. The requirements will include an eight character alphanumeric password, two uppercase letters, two lowercase letters, two special characters, and two numbers. This will make it more difficult for the password to be breached. The AUP will also state that the company systems will only be used for work related purposes. All social networking sites and many other miscellaneous sites will be blocked. The user will also have to consent to monitoring when signing the AUP.

News about this particular virus hit the headlines of a locally circulated newspaper, The Daily Item. This has alerted the schools and hospitals in the area. The CDC calls this illness ‘fifth disease’ and there had been five cases of outbreak in the local schools. The virus occurs typically among children and is relatively well-tolerated.

The viral infection is caused by the human parvovirus B19, which commonly affects children between ages five and fifteen. B19 virus causes a childhood rash called fifth disease or erythema infectiosum which is commonly called slapped cheek syndrome (CDC, 2012). The virus was discovered by chance in 1975 by Australian virologist Yvonne Cossart (Reamy and Hodge, 2007). At the onset of the infection, the virus-infected person will be observed with a low-grade fever and symptoms resembling those of a mild cold.
