From the Paper "Asynchronous Transfer Mode is a digital technique for high speed switching. The unit of multiplexing and switching is a cell which comprises a short fixed length information packet with a fixed length header to carry signalling information. By offering access at the cell level, information from many sources with widely differing activity patterns and transmission rates can be interleaved on a single transmission link or switched through an ATM node. As in other packet switching environments capacity is used only when it is needed."
Abstract This paper introduces QOA and follows with describing its function. It then details the differences between ATM and MPLS, the values of MPLS QOS and ATM QOS, traffic engineering, congestion problems and levels of hierarchy. The conclusion compares two solutions for QOS: an ATM switch and an IP router and touts ATM as the preferred solution. The paper finishes by holding that MPLS QOS could replace ATM QOS, but that is not likely to happen in the near future.
From the Paper "Simply put, multi-label switching (MPLS) brings the traffic engineering capabilities of asynchronous transfer mode (ATM) to packet-based network by tagging IP packets with "labels" that specify a route and priority (Flannaghan, 2001). MPLS unites the scalability and flexibility of routing with the performance and traffic management of layer 2 switching. MPLS can run over nearly any transport medium, including ATM and Ethernet, rather than being tied to a specific layer-2 encapsulation. Because it uses Internet protocol (IP) for addressing, it uses common routing and signaling protocols.
MPLS was not designed to replace ATM but rather to compliment it. MPLS eases complexity by mapping IP addressing and routing information directly into ATM switching tables. The MPLS label-swapping paradigm employs the same mechanism that ATM switches use to forward ATM cells. In the case of ATM-LSR, the ATM forwarding component performs the label swapping function. Label information is carried in the ATM Header.
MPLS has the ability to run over routers in addition to ATM switches, while providing the control component for IP on both the ATM switches and routers. For ATM switches PNNI, ATM ARP Server, and NHRP Server are replaced with MPLS for IP services yet the ATM control plane remains preserved (Zheng, 2001). PNNI is still used on ATM switches to provide ATM services. Therefore, an IP+ATM switch delivers both ATM for fast switching and IP protocols for IP services in a single switch.
In the past, at a specific performance level, the price of a router was usually higher than the equivalent ATM switch. With IP+ATM LSRs, the forwarding performance is determined by the capabilities of the ATM switches, whereas the functionality is comparable to a router. Moreover, IP+ATM switches may also have similar price and performance characteristics to ATM switches."
Abstract This paper examines how the American Disability Act (ADA) was created for the benefit of millions of Americans with disabilities, such as blindness and paralysis, and how it provides rules and guidelines that take care of and protect those who suffer from disabilities from access to social environment. It shows how one of the guidelines in ADA is to remove and eliminate problems encountered in ATM access by the disabled persons and how, in 1992, ADA guidelines were implemented for ATMs in a law that resolves the concerns of Americans with disabilities. It analyzes the effect of these guidelines on ATMs, as well as bank issues, and the proposed ATM technological changes.
From the Paper "The proposal of the Access Board to allow speech capabilities on ATMs presents a number of issues to manufacturers of the machines and to the banks. First, the cost of implementing the proposed changes on existing machines is expensive, granting that each bank maintains a large number of ATMs. Second, ATMs has lifespan. Instead of upgrading ATMs whose lifespan is near to expire, after the effect of the revised ADA, replacement of expiring machines is a more practical option. Such will cause burden on the banks. Third, enhancement of existing machines presents difficulty to manufacturers. The flexibility of the proposed changes of supporting speech capabilities to facilitate ATM access for the visually impaired will require time, effort, and new materials to modify the machines."

Abstract The development of cards which can access different monetary services electronically has been the major boost to electronic commerce. Many computer users today are accessing commercial enterprises on the Internet, but millions more have indulged in a different form of electronic commerce simply by using their ATM card, debit card, or credit card in the course of daily business. The dissemination of such cards has been part of a long-term and evolving marketing strategy on the part of banks and other financial institutions to change the way people do business both with their banks and with retailers of various sorts.

INTRODUCTION
The development of cards which can access different monetary services electronically has been the major boost to electronic commerce. Many computer users today are accessing commercial enterprises on the Internet, but millions more have indulged in a different form of electronic commerce simply by using their ATM card, debit card, or credit card in the course of daily business. The dissemination of such cards has been part of a long-term and evolving marketing strategy on the part of banks and other financial institutions to change the way people do business both with their banks and with retailers of various sorts. Some believe this could one day lead to a cashless society where all commerce is conducted through the use of plastic cards with ..."
This paper reviews many examples of advanced electronics, which are playing very critical roles in many areas including the biomedical and learning environments.
Abstract This paper explains that electronics technologies empower man to do things that were never imagined before such as completing advanced tasks faster and easier such as the automated teller machines (ATMs). The author points out that advances in the discipline of biomedical engineering have made the impossible "possible" by working closely with doctors, nurses and other healthcare workers to develop a range of computing, instrumentation, imaging and telemedicine equipment. The paper relates that electronic forms of learning, calls "e-learning", have evolved in different methods, which makes use of assisted programs and software in which the speed of teaching can be adjusted to the learning ability and speed of the learner and to physical impairments.

Conclusion
From the Paper "The truth that electronics aid humanity may be a subject for debate. However, it must be noted that nothing else may beat your doubt on electronics but the fact that we can derive from others' experiences that the technological advances in electronics really assist man in sustaining his life and surviving from the weaknesses of our physical body. More so, we may derive such information from our relatives and friends who may have experienced recovering from diseases with the aid of advanced biomedical machines, made possible by advanced electronics. Or, you can also ask this question to yourself to provide a view on how effective do you really believe can technology as applied in electronics will help, assist, and aid humanity?"
Abstract For many, automated teller machines (ATMs) are simply a way of life. There were introduced nearly 20 years ago and today, many bank customers never go into a branch after opening their account. But today's ATM cards can also be used to make purchases at retail outlets and even on the World Wide Web, another innovation which was not envisioned 20 years ago. The videophone has become video conferencing, and cameras which use film may be made obsolete by cameras which use a floppy disk for recording images. Electronic pagers, once the purview of doctors and others who needed to be notified in case of emergencies, have now become commonplace and are used to summon diners to their table.

Abstract This paper explains that prototyping is the process by which physical mock-ups or models are made up, based on the proposed designs now using three dimensional computer models, referred to as "Rapid Prototyping". The author points out that one of the most complex problems being faced by the businesses of today, including the banking industry, is the re-designing and the integration of the existing business processes; in the context of this "change management", prototyping not only saves costs but also demonstrates the viability of the design being created and developed. The paper relates that the system of 'rapid prototyping' is very important in today's fast paced, computer-literate, internet environment in which the banking industry competes through websites, ATMs and even soon mobile phones.

From the Paper "One of the most useful methodologies that these businesses are finding extremely useful and practical is the method of re-designing a business process design named 'Business Process Re-engineering Methodology' that explains in great detail how the existing design can be changed and re-modeled to suit the newer business processes and therefore the newer requirements. This new design is referred to as the 'Product Based Development Design', and the innate strength of this method lies in the fact that the method of 'prototyping' is used extensively throughout the procedures described. Prototyping is mooted as the method by which the end-user can use his inputs for the purpose of authenticating and validating the process designs described. It is a fact that all over the world, all the various businesses are being either fine-tuned or re-designed or re-engineered or value added or right sized or re-aligned, in the name of Business Process Re-engineering or what is also known as 'BPR' to dramatically improve the existing business."
From the Paper "The automated teller machine (ATM) has become an integral part of banking throughout the world. Originally perceived as "cash machines" which would dispense cash to depositors, today's ATMs can accept deposits, sell postage stamps, print statements, and be used at institutions where the depositor does not have an account. Due to recent legislation, in fact, it is no longer necessary for ATMs to be affiliated with any financial institution, and many are now privately owned. This research examines the history of the ATM, considers the reasons behind its widespread use, and evaluates the future of the ATM and related banking services."

From the Paper "Introduction
For many years, science fiction writers and futurists have predicted the end of the cash-based society. Advances in the technology which supports financial transactions has already greatly reduced the amount of cash necessary for many everyday events, and most individuals conduct at least some cashless transactions on a regular basis. The move toward a cashless society has occurred over centuries, but the technology of the twentieth century has propelled it faster than ever before. Yet despite the rapid technological advances of recent years, a cashless society remains well in the future. This research examines the factors which have moved society away from an entirely cash-based system as well as those factors which prevent society from being entirely cashless today."

The broadband network concept came from the fact that a wide range of voice, data and video service can be simultaneously carried on the same optical system. Broadband is the provision of subscriber access targeting business and residential customers. It is regarded as an all purpose network that will provide integrated access and support a wide variety of applications in a flexible and cost-effective manner. Because of the impact that broadband has, and will continue to have, on the computing environment, the various modes which support the technology are important. This research focuses on one of these modes, asynchronous transfer, and considers its current position relative to other broadband networks, such as frame relay and SMDS. The future of ATM is also considered.

From the Paper "Introduction
Local governments have the delicate task of balancing growth against quality of life, and of maintaining a sound economic base which can support the infrastructure (schools, public services) necessary for day-to-day activities. Some cities actively court new business and pass regulations which favor commerce. Property tax incentives for new businesses, enterprise zones and low.cost fee structures can all be ways in which communities seek to attract commerce which will contribute to economic growth. Some communities, however, seek to minimize growth. These communities may favor remaining largely residential and seek to attract the smallest amount of commerce necessary to support the residential "flavor" of the area. High-technology companies, which offer high.paying jobs and little pollution, can be particularly attractive to these ..."
Abstract This paper explores the growth of the internet over the past 30 years as it experienced many different obstacles in its development such as standards wars, protocol wars and the like. The newest obstacle is congestion on the telecom networks. This proposal discusses various new technologies that can solve this such as XDSL, Optical, ATM, Satellite and Cable. The writer aims to find an efficient and cost effective solution to this problem for the enterprise.
From the Paper "As the Internet has grown, congestion over the telephone networks has increased causing data overload on circuits. Tele.Com's (1996) editors proclaimed in 1996 ?"after a century of predictability, the telephone network as we know it is fading into oblivion"? . Solutions to this problem are varied but all involve totally digital network lines. Broadband solutions ?"promise speed, but the reality is often limited by internet speeds, backbone connections, switch capacity"? (DSL Prime.Com, August 2000) which is why there are so many obstacles for new technologies to overcome no matter how fast they are. This paper will discuss the various new technologies and which one(s) will be the best for implementation while lowering costs and increasing efficiency.
