Customers' Adoption of ATM Channel in Ethiopian Commercial Banks

Customers' Adoption of ATM in Ethiopian Commercial Banks

According to this study findings demographic characteristic variables were strongly Vassociated with adoption of ATM. Younger users are easy to adopt new technology than elders, monthly income, occupation, educational background and marital status are the main factor for the adoption of ATM. The findings of this study showed that the variables that influence to adopt ATM were convenience of location, convenience of operating hour's (24/7 accessibility of service), speed of transaction, security, accuracy, satisfaction and users previous experience, knowledge of computer and maturity in banking experience were the main factors of adoption.

ATM Hacking and Implications

This book begins with a broader discussion of cybercrime and attacks targeting ATMs and then focuses on a specific type of cybercrime named “ATM Hacking.” It discusses ATM Hacking from a more full scope of aspects, including technology, modus operandi, law enforcement, socio-economic and geopolitical context, and theory development. After unpacking a classic case of ATM Hacking and its modus operandi, implications for cybersecurity and prevention, intra- and inter-agency collaboration, and theory development are presented. This book also demonstrates the analysis of extensive qualitative data collected from a high-profile case in which European criminal group hacked into a London voice mail server belonging to a Taiwanese financial institution – First Commercial Bank,. Then it programmed dozens of ATMs to “spit out” millions of dollars of cash. The successful crackdown on this type of crime is rare, if not unique, while the number of similar crimes has increased enormously in recent years and the trend seem to continue unabatingly. Further, the implications go beyond a country or a continent. Intra- and inter-agency collaboration among players of law enforcement is essential to the case especially in the police context of “turf jealousies.” The authors seek to document the ways in which agencies collaborate, as well as the perceived benefits and challenges of cooperation. Whether the broader political and contextual climates in which these agencies operate, limit the extent to which they can cooperate. This book is useful as a reference for researchers and professionals working in the area of cybercrime and cybersecurity. University professors can also use this book as a case study for senior seminars or graduate courses.

Performance Evaluation and High Speed Switching Fabrics and Networks

ATM, Broadband ISDN, and MAN Technology (A Selected Reprint Volume)

A handy source for practicing engineers and researchers, this book offers collected examples of successful performance evaluation of high speed telecommunications switching fabrics such as ATM networks and high speed interconnection technology for computers. It emphasizes the performance evaluation of such switches as they apply to predicting a proposed system's performance through the use of statistical models -- a cost-saving way for communications engineers to test the design of a system without having to construct it.

Quality of Service Performance of ATM and IP.

Asynchronous Transfer Mode (ATM) with its Constant Bit Rate (CBR) and Variable Bit Rate (VBR) services is a network architecture tailored to real-time applications. The Internet Protocol (IP) systems--though initially designed for non-real-time data--are now being augmented with Integrated Services IP (IntServ) and Differentiated Services IP (DiffServ) in order to support these applications. Given the network circumstances, what Quality of Service (QoS) should the real-time applications expect from the above services? Can these services commit to the requested QoS of the real-time applications? This thesis attempts to answer the above questions by evaluating and modeling the performance of the underlying ATM and IP layers. We study the phase dependency in the CBR delay process, and propose a Gamma distribution to model this process. The generality of this model over variety of ATM network scenarios is tested. We analyze and formulate the Cell Delay Variation (CDV) of CBR and VBR connections. We demonstrate that the receiver-time can be divided into several epochs. We find a periodic behavior in the cell-delay-correlation of a CBR connection when being multiplexed with similar (homogeneous) connections. Next, we consider a heterogeneous environment consisting of ATM and IP networks. Resources at both ATM and IP nodes (switches) are reserved by the Guaranteed Service IP, one of the two services comprising IntServ. The essential factors in this investigation are the overhead of various protocol layers and the size of the packets generated by the application. Insofar as packet delay-jitter is concerned, the performance of IP-over-ATM is very close to that of the native ATM. Although, the buffer size requirement of the native ATM is considerably less, IP-over-ATM can still be superior because of the low memory cost. We implement the DiffServ framework comprised of Premium, Assured, and Best effort service classes. We demonstrate the superiority of Diffserv over the per-flow services. We investigate the ability of the RIO ('Random Early Discard with In and Out') mechanism to effectively discriminate the Assured traffic from the multiplexing best-effort traffic. We dynamically measure the traffic existing inside the network, and apply the measurement to the network control mechanisms. We examine the Weighted Fair Queuing (WFQ) mechanism with dynamic weight assignment. We find that WFQ can only marginally improve the network performance. Finally, we show that shaping a Premium flow can exceedingly increase the overall packet delay and jitter. (Abstract shortened by UMI.).

Moneymover ATM Introduction

Though leading its competitors in deposits, FNB was not perceived as a market leader because it had no automatic teller services. To enchance its image an an innovator, appeal to ATM users, and improve its geographic penetration, FNB introduced ATMs in late 1982. Specifically, the bank wanted to activate 8000 cards and achieve a monthly transaction rate of 4000 by the end of 1982. Employees at all levels received sales training, a personal demonstration of an ATM and a cash incentive for every customer they signed up. Statement stuffers and direct mail announced and explained MoneyMover Cards to customers. Advertising to the general public was done via newspapers, radio and billboards. The results of the campaign showed that 8100 cards had been activated and there were 4500 transactions per month by the end of 1982, and 5500 transactions per month by May 1983. In addition, staffing at ATM locations held constant or was reduced.

An Emperical [i.e. Empirical] Study of Video Application Performance Over ATM and Ethernet Networks

Abstract: "Over the past few years, there has been a strong and growing interest in faster network technologies such as FDDI and ATM. However, the perceived throughput at the application level has not always increased accordingly. Various performance bottlenecks have been encountered each of which has to be analysed and corrected. This paper presents a performance evaluation of continuous video data streams over ATM networks and compares them with similar experiments over Ethernet networks. The ATM LAN testbed for these experiments consists of three SG R4000 Indigos workstations connected by ATM Fore first generation interface cards and a Synoptics ATM switch. It is expected that video applications would run faster on ATM networks than Ethernet networks. A preliminary examination suggested to us that data movements through the protocol stack and the processing overheads were considerably high and that with some parameter settings, experiments with Ethernet would perform four to five times better than those with ATM. To address and explore this issue, a packetisation process has been added within the video application that would split each video frame into a number of packets. We show that by implementing a packetisation process at the application level, the end host is able to deliver cells at a faster rate. The sensitivity of these parameters, and also the overheads involved are discussed. The results are consistent over a range of video frame sizes: CIF(25 K), QCIF(101 K), and SCIF(405 K)."
