With the New Technology coming out today the world is headed in a new direction. The mobile phone has made it made it easier for people to make and receive calls over a radio link while moving around a wide geographic area. It connects to the cellular network that is provide though a mobile operator allowing access to the public telephone network. The new modern telephone supports a side variety of other services such as text messaging MMS, email, internet access, short range wireless communications infrared, Bluetooth, and various other applications. Two engineers with Intel’s Software and Solutions Group describe the benefits of the UEFI pre boo software t mobile and embedded devices. The Unified Extensible Firmware Interface specifications are meant to facilitate emerging technologies, services, security mechanisms, and user experiences that come into play prior to loading the device’s OS. It was designed to allow for cross functionality between devices, software, and systems, unified Extensible Firmware Interface specifications encourage innovation, and helping to drive the evolution of the next generation technologies, such as the expansion of embedded and non pc systems. The UEFI provides a plurality of services, including console, storage, and networking services. Hosted and implemented by the UEFI Forum, this technology enables firmware innovation by promoting a standardized, extensible, and interoperable firmware interface that extends far beyond the PC and into the future of computing and the realm of embedded systems. Systems were analog or simple state, machine based platforms using SSI, MSI, or PLDS. The microprocessor ushered in a wave of continual evolution, demonstrated by the embedded market shift from 8-bit, to 16-bit, to 32-bit, to 64-bit microprocessors. This reflects the progression from simple cell phones to smartphones, from mechanical brakes to microprocessor-controlled anti-lock units, and from handwritten directions to satellite-based navigation systems. Along with this advancement, in-vehicle infotainment and digital signage emerged, along with many other instances of hidden intelligence in the world around us — providing several new modes of utility for UEFI.

With the increasing richness of the software ecosystem and the growing complexity of platforms, a layer between the operating system kernel and the platform became a necessity. As UEFI-enabled PC platforms became pervasive, a new challenge emerged. Many of these operating systems require customized firmware with OS-specific hardware interfaces in order to fit into the PC firmware ecosystem model. Ultimately, everyone — from the vendor, to the developer, to the end-user — wants to work smarter, as opposed to harder. The contemporary challenge is to provide the embedded platform firmware with capabilities comparable to the traditional model. The firmware must be OS-agnostic, scalable across different platform hardware, and capable of enhancing the efficiency of developers. With its capability of supporting scalability, UEFI specifications fulfill a unique role. UEFI specifications provide a consistent set of OS-agnostic software interfaces that abstract the underlying details of the platform. These abstractions can be layered upon SATA, SCSI, iSCSI, USB Bulk Only Transport, or any other block device. By traveling with the system board, UEFI serves as a set of built-in drivers and capabilities upon which operating system loaders and pre-OS applications can depend.
From its onset, UEFI firmware was designed to support extreme scalability, as shown in the diagram below. There are no design differences between the normal boot and an optimized boot. Optimizing a platform’s performance does not require violating any of the design specifications. Additionally, a UEFI standards-compliant design need not encompass all aspects of the standard PC architecture; instead, its scope can be limited to the components required for platform initia

...Meanwhile, user behavior has played a crucial role in system security especially in authentication area. Typically, authentication is achieved by account and access password verification, token such as access card identification, or biometrics which is referred to user's body parts. However, those approaches are not effective and efficiency enough as password will lose their effectiveness once they are compromised; token can be stolen or lost; while biometrics requires high installation cost. Moreover, once authentication occurs, there is no guarantee that the initial authentic user is still the same person. As a result, the system security is strengthened by incorporate continuous authentication during session monitoring the user behavior. If the behavior is found to be anomaly, re-authentication process is performed immediately. At system level, user behavior is also useful for intrusion detection. An intrusion can be identified before it happens based on some specific behavioral patterns indicating of suspicious identities or actions. Theoretical Perspectives As mentioned earlier, computer system is built for user but not vice versa. Thus, the computer system should behave as user expected and required. In order to understand the user, his or her behavior on using the system must be known. The following were some of the common user behaviors: (12) User doesn't like to wait.

Dependence on Tecnology

...ENC-1101 19 julio 2014 Word count 1515 Technology’s Takeover: Is it too Late to Unplug? “Though technology has allowed us to improve and modify traditional tasks, it has also clouded our realization of the dependency we have on it” (Sala). Ever since men’s first thoughts, technology, as a synonym for development, has been around. From the first fire pit, to the first boat design, and finally to the first electronic device, through eras, the human race has managed to discover more ways to do things faster and easier, and to make their life simpler. The object of this research is to persuade and to inform the general public interested in technological impacts and the negative effects it has brought to those who over use it and also to catch, as a desired audience, that part of society blind to such gravity. Even though these new inventions have indeed given us the ease to have almost everything one click or touch away, a dependence on these advances has been developed by their take over, and therefore a harmlessness and ignorance to the possibility of living without it affecting social communication, education, and society’s behavior. SOCIAL COMMUNICATION Just a couple of decades ago, meeting a friend at a café or asking another person for a dance, were two of the most common ways to socialize and to get to know others. In the present, it does not usually happen. Social networks, apps, and date-finding websites have substituted that habit, and now we communicate through...

Aspen Tecnology

...Aspen Technology Case – Group 1 Problem Definition Aspen Technology, Inc. has undergone rapid growth over the past thirteen years and the current business model has proven to be outdated. The young software company’s biggest challenge occurred in 1994 when they went public in a $31 million dollar initial public offering. The IPO effectively enabled the company to finance its increasing research and development spending, but it also increased the need to hedge risk associated with the growth of the multinational organization. AspenTech has become a public company with more risk adverse investors who want to invest in the core business of the firm, but do not want to assume its foreign exchange risk. Foreign exchange risk is a core risk for AspenTech, because much of its business is done outside of the United States. Its current risk management policy is ineffective because it does not currently account for its foreign expenses, which create an effective “natural hedging.” The ideal scenario would be to match foreign expenses to its respective sales, and completely hedge the difference, but AspenTech’s outdated hedging policy has failed to account for any of the expense exposure in Belgium, and has “over-hedged” exposure in Japan and the United Kingdom. Description of Methodology In this case we will identify the reasons Aspen Technology, Inc., has foreign exchange rate exposure, discuss where it comes from, quantify how much exposure they have, and provide recommendations...

One Day Without Tecnology

...La storia del jazz, come quella di molti altri generi musicali popolari, soprattutto quelli che affondano le loro radici nella tradizione degli schiavi afroamericani e indonesiani, è assai povera di documenti e riferimenti, in special modo per quanto riguarda le origini e i primi anni. Le prime fonti orali sulla nascita del jazz a New Orleans risalgono ai primi anni del XX secolo mentre le prime fonti scritte al decennio successivo. Il jazz fu creato dagli africani deportati negli Stati Uniti e schiavizzati, che cantavano per alleggerire il lavoro. Il genere si sviluppò in modo esponenziale tra il 1915 e il 1940, diventando la musica da ballo dominante tra il 1930 e il 1940, anni in cui i brani delle big band si trovavano regolarmente ai primi posti delle classifiche. A questo periodo seguirono diversi decenni in cui il jazz si caratterizzò in maniera crescente come una musica d'arte, tipicamente afroamericana. Nel frattempo il pubblico statunitense del jazz si assottigliò, mentre la musica destava un crescente interesse in Europa e nel resto del mondo. Questa tendenza, iniziata col movimento bebop nel 1945, raggiunse l'apice negli anni sessanta con il movimento free jazz, che mirava all'emancipazione totale del musicista. Seguì un periodo di involuzione e di marginalizzazione che terminò negli anni ottanta, durante i quali una generazione di giovani musicisti infuse nuova vita perseguendo diverse tendenze anche in assenza di uno stile dominante: nacquero così diverse scuole...
