...Assignment 2: 3G wireless networks and 4G networks sweetie Professor: CLIFTON HOWELL CIS 500 February 03, 2014 INTRODUCTION For one to compare and contrast 3g versus a 4g network, we first have to define what a wireless network is. Radios are considered to be the most popular for wireless technologies. Wireless communication is transferred between multiple points which are not connected to an electrical conductor. Wireless is playing a big part in the cellular network communication field. Literally, on all the channels on TV it’s impossible to go 3 minutes without seeing advertisements from Verizon, AT&T, T-Mobile, and Sprint claiming to be the best network provider. Each cell phone provider promote their own version of 3g and 4g networks. Carriers do this to draw the attention to endorse their services and to bring in new customers. As a result, it makes it very difficult for consumes to make a choice between the competitors. Consumers make their choice between providers based upon the price and coverage which are both vital to most consumers. With all the promotions and dramatic advertising it can be hard to know the truths about each wireless company. In this paper 3G and 4G networks will be compared and contrasted, 4G LTE, 4G WiMAX and 4G WiBro networks and competition will be identified. Lastly, this paper will identify why the competition between the 4G LTE carriers has been so fierce. 3G and 4G Networks Technology has allowed advance speed to...

...Case Study: #1 - The Big Data Challenges Arnechia Washington Professor Durgin CIS500 Info Syst Decision-Making January 26, 2014 Volvo Car Corporation has incorporated the cloud infrastructure into its networks to globalize the company. “With hundreds of sensors and CPUs embedded throughout the car — from the brakes to the central locking system — data is now being captured for use within the vehicle itself, and also, increasingly, for transmission via the cloud back to the manufacturer” (Strader, 2011). Volvo’s data Warehouse has multi-terabytes of data from the hundreds of sensors and CPU’s that are embedded throughout the car as well as data from customer relationship systems. The Cloud platform allows implementing and evaluating real-time information systems to transform data into knowledge. This will give Volvo a competitive advantage over other car companies and allow their offices no matter the location to immediately take advantage of the data that is stored. There are two different cloud infrastructures within their infrastructure: service cloud and vendor hosting. Service cloud is used to support the customers and while their customers are operating the vehicles. This will enhance the car from the information that is gained based on the design and performance level of the car. Vendor hosting is used for the data that is located in separate warehouses. This platform allows the data to be consolidated into one place and reduces the cost to maintain, operate...

...Wireless Networks 4G Wireless Networks Britney Green CIS 500: Information Systems for Decision Making Professor Frank Lazzara November 4, 2012 4G Wireless Networks “Wireless networks use packet switching and wireless networks. Patching switching is when the path of the signal is digital and is neither dedicated nor exclusive. Routers are devices that forward packets from one network to another network. Packets occur when the network breaks a file or e-mail message into smaller blocks of specific size. Wireless routers are actually wired routers with wireless access points (WAP) built in. It provides both wired and wireless at the same time”. (Turban & Volonino, 2011) Third generation also called 3G; of cellular telecommunications technology supports multimedia and broadband services. Broadband means fast transmission speed. It is faster than the 1G and 2G. The third generation networks have far greater ranges because they use large satellite connections that connect to telecommunication towers. The fourth generation is called 4G. 4G mobile network standards enable faster data transfer rates. (Turban & Volonino) Right now 4G is the latest generation of wireless data technologies. It carries average download rates of 3 Mbps or more. “In contrast, today's 3G networks typically deliver average download speeds about one-tenth of that rate. The 2G and 3G started separately with their own purposes; soon both will be converted to the 4G network”...

...CIS 500 Weeks 6, 7, 8,9,11 Discussion Questions Week 6 * Mobile banking features have added several advantages for customers however; there are security risks that come with them. Determine the security risks with respect to phishing, smishing, vishing, cloning, and a lost or stolen smartphone that have been experienced by the financial services industry as a result of mobile banking. Phishig – Is when malware is downloaded on to a device and it attempts to obtain personal information. It lies in wait and gathers information from apps such as a mobile banking app to gain your login and password. If you bank does not have proper security in place this can lead to your account getting hacked and loss of money. Smishing- This is where fraudulent communication occurs in the form of a text message in order to obtain personal information. Vishing – This is similar to smishing instead of getting information through text it is obtained through phone calls or voicemails. Cloning- The transfer of information from one device to another device including the electronic serial number When a smartphone is lost or stolen this can lead to a compromise to a person’s personal information since it may be on the phone. I bank with Bank of America and use the mobile app to manage my account transfer funds, pay bills, deposit checks and so on. The app does not store the password but it does store the user login. You are unable to just log in to it from a new device or location without verify...

...Information Technology continues to improve over time. In today’s society, with the help of technology, mobile phones have the capability of acting like a computer and so forth. So with the creation of the program COMPSTAT, there was numerous years of data that was added into the database with new daily information added to predict which areas would have the highest rate of crime based on what has happened in the past (Goode, 2011). Before COMPSTAT, the officers would patrol spots that they thought might be a high area of crime based on their experience in the field (Goode, 2011). This allows the police officers to be able to target the crimes when they are taking place to prevent them from occurring based on the presence of the police officers. This also allows for officers to catch people in the act to be arrested and possibly file more charges against the criminal. This advantage allows for time to be used more wisely to go off of the data that is known for trouble spots to keep the crime down in those areas. The disadvantage of the program would be that if there was not any crime occurring in the area that the officers were sent to that it would be the same as patrolling as they would be wasting time until they were dispatched to take care of something else. With the patrolling of the streets, it more likely that the officers are waiting for a crime to take place and then they pull someone over . With COMPSTAT, it is more like a stakeout where they wait until the crime...

...Assignment 4: Data Mining CIS 500 Dr. Besharatian Submitted by: Eric Spurbeck December 7, 2013 Abstract This paper will discuss the process of data mining, how it is used, for what purpose it is used and what information can be gathered from the data, which is compiled from data mining. Assignment 4: Data Mining Webopedia (2013) defines data mining as, "A class of database applications that look for hidden patterns in a group of data that can be used to predict future behavior. For example, data mining software can help retail companies find customers with common interests." This means that large groups of data that is derived by information obtained through customers, customer purchases and customer buying habits. Businesses use this information for a variety of reasons; it is used for purchasing merchandise, tracking how certain merchandise is selling and even customers buying habits. Webopedia goes on to state that "data mining is popular in the science and mathematical fields but also is utilized increasingly by marketers trying to distill useful consumer data from Web sites." Predictive analytics are used to understand customer's behaviors, according to the article Predictive Analytics with Data Mining: How It Works (Siegel, Feb. 2005) it describes how this method has a predictor. This is "a single value measured for each customer" this is based on the customers purchased over a period and sets higher values for the most recent customer purchases. The...

...Assignment: 1 Error Handling in an Activity Diagram LaShantel Wilson Strayer University Dr. Richard Brown April 18th 2016 Error handling are routines in a program that responds to errors (Encyclopedia). The measurement of quality in error handling is based on how the system informs the user of such conditions and what alternatives it provides for dealing with them (Encyclopedia). This paper will give a narrative which describes the changes and added error handling pathways in the diagram within this paper. There will be an overview of the errors, an explanation as of the main changes checking are imperative within the process, and overview of possible errors. A diagram will illustrate the updates of two (2) error handling pathways. Error Handling Pathway Ridgeline Mountain Outliners (RMO) is a large retail company that specialize in clothing and related accessories for all types of outdoor and sporting activities (BOOK). One approach to handling errors in received data is for the receiving system to send the data back to the sending system, often with an indication that an error has been detected by the receiving system (GOOGLE). When an enterprise IT system includes a sales system and a financial system, the sales system may send data to the financial system, which is only capable of accepting data that passes particular types of validity checks and other types of data consistency checks. When data received by the financial system does not pass the data consistency...

...Term Paper Keenan Rhines Strayer University Dr. Hammond Elbedour November 26th, 2014 People are moving into a new era of mobile computing, one that promises greater variety in applications, highly improved usability, and speedier networking. The 3G iPhone from Apple is the poster child for this trend, but there are plenty of other developments that point in this direction. In addition to this trend, many mobile applications were designed that perform specific tasks for the mobile user. * Assess the effectiveness and efficiency mobile-based applications provide to capture geolocation data and customer data, and quickly upload to a processing server without users having to use a desktop system. Nowadays, according to statistic, Ninety-seven percent of all smartphone users use mobile applications. Fifty-eight percent of those smart phone users use location-based applications. The results were raised from surveys done by a nonprofit global information security association called ISACA (previously known as the Information Systems Audit and Control Association). The location-based activities were implemented via applications installed on smartphone. These apps using the users current locations was calculated fifty-nine percent of the time but tagging photos on social media such as Twitter or Facebook was estimated forty-four percent. Besides, several mobile apps that capture geographical information, sim-card information and other personal information to share on social...

...Predictive Policing By Gus Finklestein Strayer University Abstract Predictive policing is a relatively new crime-fighting technique that can be used to both deter crime and catch criminals red-handed. Combining computer technology together with area- specific crime data, reports are generated forecasting precisely when and where crimes are most likely to occur. Police departments maintain records, data, and or databases which log huge volumes of information on crimes, criminals, suspects, and much more. Inputting that information into a sophisticated computer program designed to predict crime, to within a 500 by 500 foot location, is proving to have some merit. With technological advances, police no longer radio headquarters to retrieve basic information like license plates. In fact, the majority of police possess internet-connected computers in their cruisers, allowing them access to vast amounts of data. Within an organizational context, when police easily communicate and share knowledge across boundaries, and the entire country, the overall efficiency of crime-fighting and crime- solving greatly improves. Take for example an Amber Alert, the name of a missing persons report when a child vanishes. Once an alert is executed, police forces very quickly mobilize and cast a very wide net using all available resources to locate that child. This paper discusses the uses of technology, in particular predictive policing, to advance the efforts...
