Ms. Latrea Shine

The benefits of Creating VLAN VLAN’s enable the logical grouping and of end stations that are physically dispersed through a network. When users on a VLAN move to a new physical location but continue to perform the same job function, the end-stations of those users do not need to be reconfigured. Similarly, if users change their job function, they need not physically move: changing the VLAN membership of the end-stations to that of the new team makes the users' end-stations local to the resources of the new team. Since broadcasts frames are targeted and processed by all devices that create smaller domains to reduce overhead and limit resource utilization. Only those workstations in need of receiving specific broadcast or multicast traffic can exist on the domain, preventing other devices from receiving unnecessary traffic. The use of VLANs to create broadcast domains also eliminates the need for routers to handle this function, permitting operation at lower latencies compared to routers under heavy load. VLAN’s extends beyond conventional or single LAN’s to form a group of LAN’s. A VLAN can be created to provide groups of users who will be transmitting data among themselves at high volume, reducing the impact on all other workstations. These user workstations do not have to be physically moved or located near one another, since the workgroup is virtual environment and created within the switching software. Of course, some shared devices such as printers or scanners require physical access, and their placement may pose a challenge if workgroup clients are located in different buildings.

The breakdown of different broadcast domains Throughout the duration of the company’s growth and as the networks begin to expand in order to alleviate collision

...Chapter 1 1. How can information technology support a company’s business processes and decision making and give it a competitive advantage? Give examples to illustrate your answer. The term information technology refers to the various hardware, software, networking, and data management parts that are a necessity for the system to function (pg. 8). Businesses regularly utilize computer-based information systems in order to record customer purchases, keep track of inventory, pay employees, buy new merchandise, and evaluate sales trends. Without the support of information technology, businesses would ultimately fall apart. For example if a business did not choose to use computer-based information systems, they wouldn't be able to evaluate what items were selling better than others and ultimately lose valuable information for future success. Information technology can also aid in decision making for a business. Decisions are made based on analysis provided by computer-based information systems. For example a store manager may make the decision whether to discontinue an item for sale or keep it on the floor due to analysis of sales trends provided by computer-based systems. Lastly information technology helps business gain a competitive advantage. A competitive advantage is gained through computer-based information systems by applying innovative application of information technologies (pg. 9). For example a store manager installing touch screen kiosks throughout the organization...

...Information technology affects almost every aspect of the business world in today’s modern society. Within a matter of decades both internal and external processes have been transformed. For example, managers no longer handwrite reports for their office staff to type or use mail to correspond with clients or post flyers to communicate with employees. My department at Princeton University has experienced these types’of scenarios over the past five years. Five years ago, our procedures and computers systems were antiquated. The need for technology was essential to provide better communication and improve procedures, especially in a department that has over 200 employees who work in different locations throughout the University such as dorms, academic buildings, and athletic facilities. For instance, my department’s time-off request procedure and the process by which supervisors receive their daily work orders were lengthy, required several steps, and needed to be modernized. Realizing how outdated these procedures were, my department sought out several different types of technology to help improve its overall functionality. Technology acquired included, Sharepoint, Ipads, and EZ Maxmobile App. In just a short period of time, these products have significantly improved communication and procedures throughout the department and enhanced our customer service to our clients. The use of Sharepoint, a web-based intranet that streamlines the management of and access to data,...

Policing Information Technology

...Policing Information Technology Bill Smith BIS/220 July 11, 2012 Alisha Johnson Abstract Policing Information Technology Over the past 30 years technology has advanced at an alarming rate. Since the inception of personal computers and the World Wide Web a need for individual protection occurred. Government reform was needed. In the 1980s two Acts of Congress were passed, the Computer Fraud and Abuse Act of 1986 and the Electronic Communications Privacy Act of 1986. Initially we will examine the advances in technology that caused each Act to be passed. Last we will determine what new ethical issues came about from this new technology. Although some may see these Acts as an invasion of one’s right to privacy, they are essential to protect stored information from being used in a negative way. “A survey by an ABA task force in 1984 estimated that businesses and government agencies lose as much as $730 million a year to computer crime” (Wolf, 1986). Two years after this survey was published the U.S. House of Representatives passed the Computer Fraud and Abuse Act of 1986. During this time computers are becoming widely used across the country. The major change is the type of information being stored. Financial institutions both in the private and government sectors are using computers to store valuable financial information. Computer hackers illegally could gain access to this information and sell it to individuals with the means to use it or vandalize the company’s...

Information Technology Acts

...Information Technology Acts Chad T Lane BUS/220 30 June 2014 Mrs Colette Gardner Information technology is a dynamic and rapidly changing industry. Up until roughly two hundred years ago, all communication required walking, horseback, or some other form of manual labor. The telegraph was the first step down the path of information technology when Claude Chappe first invented it in 1794 (Bellis, ). The telegraph was the gateway to a plethora of other forms of communication that lead to social media, email, blogging, text messaging, etc. The internet is probably the biggest and most powerful breakthrough in information technology. With that, comes a lot of potential for people to do things they should not, say things they would not say in person, and target an audience that might have gone otherwise unreached. The Children’s Internet Protection Act of 2000 was passed in order to prevent children from exposure to pornographic material and things that are not age appropriate for young children in situations where schools or libraries receive internet at a discounted rate  (FCC,). Prior to the internet, someone wishing to purchase pornography or R-rated movies would be required to prove legal age to do so because these transactions largely took place in person. The internet has no hard and fast way of verifying age so keeping children away from things they should not see, requires use of filters and other resources to block certain material and websites. Many people will...

Information Technology in Business

...Riordan Manufacturing business chose to outsource their information technology (IT) systems and services for a variety of reasons. This choice carries with it some obvious benefits and some often not so obvious risks. Companies choosing to outsource IT must weigh the benefits and risks carefully, take measures to attenuate the associated risks and prepare their employees for the change by launching a campaign about the benefits of outsourcing. The risks involved with outsourcing mainly involve accessibility to service. According to Applegate (1995), if you rely on an outside contractor who generally has to come onsite to support your network, then [consider removing "then"] you live in a world where you simply hope critical services don’t [Contractions are inappropriate in academic writing--write it out] go down at a time when your ability to conduct business will be interrupted.

The dramatic increase in technology demands the attention of almost every person across the globe as they connect, work, and coordinate daily plans and objectives with those close and far away. Information technology is one of the largest demanded and growing systems users have available. Information technology is the use of computer and telecommunication based systems; to store, send, manipulate, and retrieve data information across the various environments for the users utilizing the systems (Wikipedia, 2014). From professional, academic and personal situations these systems are more than ever present in the daily routine. The increased demand and use of these systems does make daily tasks easier and quicker to complete, but even the most beneficial tools can come with a cost. The information systems we utilize improve efficiency and effectiveness, but open doors for dangerous, illegal, and unethical actions.

Communication and Information Technology

...Communication and Information Technology HCS/320 January 28, 2012 Dr. B Communication and Information Technology Communication has been a key element in the health care field for many years. A patient communicates to the physician what is wrong with them, the physician communicates with the nurse what is to be done, and the information is entered into the patient file. The medical biller then bills the insurance or patient by sending an electronic claim, and the payer sends back a statement of payment. All this is considered communication. Over the years technology has advanced and the ways these communications have been used have changed. Now communication is done electronically, sent by email and even text message; there is even a way to teleconference over video phone with a patient or physician. After researching new technology I found Vocera, a communication system that makes communicating between team members faster and easier. The system uses a hand held device as well as a computer based program to communicate messages even alerts to get in touch with team members. The voice activated hand held device is the size of a cell phone and is typically hung around the neck. The hand held voice activated device can be used to call another team member, or can be used to access a paging system in case of emergency situations. Physicians can use the device to turn on their status, such as on call or on lunch break. When the computer based program is accessed by a nurse looking...
