...The Job Network: Changing the way students "intern" and begin their careers I want to change the way that students and people interact with that work world. I want to create the primary website that employers go too in order to evaluate potential employees. There are many people who are looking for jobs who have many different skills; yet, they just need the opportunity to show employers what they are capable of doing. Employers are constantly facing different kinds of business challenges everyday that students/people searching for work could provide solutions for. This website is a way for students to help business professionals with their homework (research projects, investments pitches, sales information). At work, people are given "homework", problems that need solutions, research assignments, and the list goes on. People at work are often over-worked. Is there a way that these employers could post these projects to a website that students/people looking for work could then access these projects/research assignments. These students could then submit there suggestions or how they would complete the assignment. It is basically getting students to do some of the projects that people at work are doing. It makes the work of these companies easier and it could really help small businesses. It's great because the help is free and the business owners have the discretion whether to use it or not.. It gives these companies more data/options to work with. The students, if...

...because of your work hard. However, most of the students say that the network service needs to improve. If students are satisfied with the network, they would prefer study in the library. The solution is to upgrade network service which just cost few money. It benefits for everyone who studies or works in the library. There is a serious problem be concerned University of Bridgeport students who study in the library. I often study in the library. One of the network problems is network instability. For example, I have to research some information about my assignment, because my first language is not English, I always research more academic information after class or look up the unknown words in an online dictionary. However, I have to connect the UB network approximately every five minutes. I was really bothered by the unstable network here. This action which is frequently loggeing on to the internet makes my learning efficiency lower, because I cannot focus on the studying. The unstable network not only bothered me, but also bothers my friends. There are a statistic for this issue. My four friends with me went to the library to study. When they log on the network, one of the my friends disconnect after four minutes, and he logged on again. After 3 minutes, other friends disconnect from the internet. About seventeen minutes later, we are all relogging on to the UB network. Another network problem is network slow. For example, I have a good laptop. When I surf the internet...

...of student) _______________________________ Summary Schools store and process increasingly more data about students and the subjects which they study. This often includes timetable, homework and attendance data amongst many other potential data sources. In many schools there currently exists no solution for students or their parents to view this data as information from one user friendly interface. The Arnewood School is a secondary school and sixth form college which has realised the need for this kind of information to me made available to students and parents via a secure, user friendly, single sign-on interface. This project aimed to produce a web portal which integrated and displayed information from preexisting and newly designed information systems in a way which was inline with the requirements of The Arnewood School and potential users. Due to the nature of developing such a system without having any knowledge of user requirements, a suitable methodology had to be selected which allowed for vague user requirements that could change at any time. Following this, background research and user requirements gathering was completed in order ensure the solution matched both the requirements of users and the requirements specified by The Arnewood School. Finally, the solution was designed and implemented before being suitably tested and evaluated. i Acknowledgements First and foremost I would like to thank Kevin McEvoy my project supervisor for his help...

...Facebook Facebook is one of the most successful social networks ever made. What ever happened to one human being going up to another and using face-to-face interaction? Over billions of people have a Facebook account, including myself, and spend countless hours on this addictive website. This website has caused a lot of controversy with adults who have kids that are absolutely obsessed with their Facebook. In “Dad’s Encounter with the vortex of Facebook,” written by Michael Duffy, he discusses some issues he has with Facebook. He explains that the site Gives teens an illusion of privacy, has a dark side, where stalking and cyber bullying takes place and most of all that it’s a waste of time. I couldn’t agree more with Michael issues about Facebook. Michael Duffy claims that teens have an illusion of privacy on Facebook. In other words, as he states in his article, “Teenagers think their lives are private just so long as their parents aren’t tuning in.” Since these teenagers have this illusion that their Facebook is private, they think they can say and post statuses as well inappropriate pictures and they think there won’t be any consequences from this. For example, I had a friend who went to a party and took pictures of herself drinking alcohol, smoking marijuana, and dancing inappropriately on numerous guys. She then posted the pictures she took from the party from the other night, thinking her parents would never see the photos. It turns out she had an older cousin who...

...Session 10: System Architecture Tasks 1. Jesse wants me to recommend a vendor who offers an ERP strategy. I need to review the SAP and Oracle Web sites, and at least two others that offer ERP solutions, and reply to her with the results and the reasons for my recommendations. 2. Visit SCR's data library to review SCR's network configuration and then send Jesse a recommendation for the TIMS system architecture. She wants me to suggest an overall client/server design, number of tiers, and network topology. She also asked me to comment on these issues: legacy data, Web-centricity, scalability, security, and batch processing that might be needed. Jesse said it was OK to make reasonable assumptions in my proposal to her. 3. Perform research on the Internet to learn more about TCO, and develop a TCO checklist that includes the five most important elements of TCO, because of their magnitude or potential impact on TIMS. 4.
