...Create a Network Solution Name: Course: Tutor: Date: Create a Network Solution. Many methods of using computer networks for data storage have come up in recent years. The most common and popular approach which I personally prefer is the network attached storage (NAS).NAS allows businesses more affordably that before to store and retrieve large amounts of data. Most businesses do not consider the future expansion of their companies when creating their network solutions and end up exhausting their network resources. The increase in the data capacities of the electronic components used in today business world has led to the demand for a more convenient storage type. The ability to use a file server to store files has led to companies deploying large centralized NFS servers which are accessed by thousands of clients. Central file servers are seen as the basic solution to demands put forward. A file server is in basic terms a workstation or a personal computer hardware running on a network operating system (NOS).The NOS in this case boasts file sharing capabilities. The hard drives installed in the computers are used to provide the required storage space ranging from gigabytes to terabytes of memory space depending on the size of business. Many business owners are not justified by the use of a fully general-purpose computer as a server for simple storage services. This factor brought to the development of the network attached storage (NAS). NAS creates a system...

...The Bead Bars Network Solution The Bead Bar business is an arts and crafts oriented company which specialized in allowing customers to create their own bead jewelry. The company was founded by Meredith S. in 1998 and her first bead bar studio was opened in New Canaan, Connecticut. Today, the company consist of two studios in New York City, one in Long Island, one in Washington, D.C., and on in Boston, Massachusetts. There are five franchises in Kansas City, Missouri; Chicago, Illinois; Los Angeles, California; Seattle, Washington; and Miami, Florida. The Bead Bar on Board is a portable Bead Bar designed for cruise ships, the portable bar can be placed on deck or in a lounge for the cruise members to create their own bead jewelry. Now, the Bead Bar became so popular that it outgrew its paper-based system and is in need of an upgrade to a more effective technology system. The old file cabinet and orders on paper are just not efficient enough to compete with today’s technology advancements. Today’s information technology systems have the ability to globalize and reach customers all over the world, which are of benefit for the Bead Bar to reach more customers and make more sales. Upgrading to an information technology system will also solve most of the problems which comes with a paper-based system such as lost orders, invoicing errors as well as delays in order fulfillments.

...Network solutions are continuously evolving in a changing economy. The five industries that were researched are banking, retail, judicial, law enforce, and military. The investigation included but not limited to be the history of the different networks, current network solutions, and than the future challenges of each varied business. The banking industry has evolved greatly due to the continuous improvement in technology and network solutions. The first bank in the United States of America was established by Congress in 1791 called the Bank of the United States. The first network innovation breakthrough that is a precursor to online banking was the invention of the telegraph. The telegraph was invented in 1844 by Samuel Morse which for the first time it allowed mankind the convenience and comfort of communication. For the first time it allowed banks to communicate across great distances in a qualified short period of time. The next great leap forward in network solutions in the banking industry occurred in the late 20th century. The wide distribution of automated teller machines (ATMs) by the mid-1980s gave customers 24-hour access to cash and account information. On-line banking through the Internet and banking through automated phone systems now allow for electronic payment of bills, money transfers, and loan applications without entering a bank branch. The current network of the banking industry has made it possible to deliver services throughout the branch...

...FUNDAMENTALS OF SURFACE MODES: ¥ COLLOIDS ¥ means ÒglueÓ in Greek ¥ was coined in 1861 by Thomas Graham. ¥ ¥ ¥ ¥ ¥ WHAT IS A COLLOID? usually consists of two phases; one continuous phase in which the other phase is dispersed. Size of particles: larger than the size of molecules and small enough for the dispersed phase to stay suspended for a longer period of time. ¥ No strict boundaries for the size limits. OFFICIAL DEFINITION ¥ In 1903 Wolfgang Ostwald formulated the official definition of a colloid: ¥ a system containing entities having at least one length scale in between 1nm and 1µm. ¥ For smaller particles there is no distinct boundaries between the phases and the system is considered a solution; ¥ for larger entities the particles will fall to the bottom due to the gravitational force, and the phases are separated. 1 2 3 MESOSCOPIC PHYSICS ¥ The particle size is in the so-called mesoscopic range in between the macroscopic and microscopic limits. LARGE INTERFACIAL AREA ¥ One very important quality of the colloids is the large interfacial area between the dispersed and the continuous phases. WHAT EFFECTS HAS THIS? ¥ This means that interface effects and hence the electromagnetic surface modes, are very important for the properties of the colloids. ¥ It costs energy to create this much surface and the particles would clump together if this isnÕt prevented. ¥ Usually the particles are charged and hence repel each other. 5 6 4 Four states...

...Peachtree Healthcare (PH)’s mission are ensures quality, provide consistency and continuity of care across the entire network, to deliver care with the highest levels of efficiency and economy, and maintain respect for patients and staff. The objective of PH is to offer all kinds of treatments so patients' care would be continued without any disruption. PH’s patchwork IT infrastructure is in critical condition, so it has major IT infrastructure problems. CEO of PH Max Berndt is trying to find the right solution. He has an option to go with monolithic system that will provide consistency across PH’s facilities but may not give doctors enough flexibility or he can choose service-oriented architecture (SOA), a modular design that will allow PH to standardize incrementally and selectively but poses certain risks as a newer technology. Evaluating pros and cons of both SOA and monolithic system, SOA seems less expensive in the long run than the monolithic system. CEO Max Berndt does not like the basic force to make homogeneous across the network hospitals, especially for non-routine stuff. So, he considers applying SOA as a new information system. Monte Ford, Sr. VP/CIO of American Airlines, recommends SOA and mentioned as “the company doesn’t have the luxury of waiting for a lot more certainty; its infrastructure needs a solutions now”. Likewise Randy Heffner, a VP at Forrester Research also recommends SOA. The interesting thing to note is that none of the experts recommend a monolithic...
