One of the most important issues that organization face is sustaining network performance in lihght of the explosion of network-based application and data transmission volume. The growth of client artitechtures, intranets, and the Internet has increased the attention paid to overall enterprise network performance. Network resource time and availibilty are widely as key issues for IS managers. Modern day organizations use multiple computer systems acrss the firm. Distributed processing enables computers in different locations to communicate with each other via telecommunication links. Basically we can divide such distributed processing into 3 primary categories. They are:
➢ Terminal-to-host processing: With terminal-to-host processing the application and database resides on the host computer. The users interact with the applications with “dumb” terminals.

➢ File server processing: With file server processing the application and database reside on the host computer, called the file server. The database management system runs on the user’s PC. When the user needs data from the file server. The file server sends to the user the entire file with the data requested. The downloaded data can be analyzed and manipulated on the user’s PC.

➢ Client/server architecture and processing: Client/server architecture links two or more computers in an arrangement in which some machines perform computing functions for end-user PC’s. Sometime either machine can perform processing and store applications. when two or more computers in an organization are linked in such a way that one acts as the client and the other as the server, and then such processing takes place. Here, usually it is the powerful server that is found to be doing the processing and data storing for its clients making organizations more efficient as proper processing can take place for the organizational data and money is saved as well during the process.

In client server approach, the components of an application can be distributed over the enterprise rather than being centrally controlled. Three application components can be distributed: the presentation component, the applications(or processing) logic, and the data management component. The presentation component is the application interface or how the application appears to the user.The application logic is the bulk of the application program, created to perform some business function and the data management component consists of the storage and management of the data needed by the application.

Client server processing is effectively divided into 5 models of implementation. They are:
• Distributed presentation
• Remote presentation
• Distributed function
• Remote data management
• Distributed data management

Students should realize that SCR foresees a dynamic future. With this in mind, an ERP strategy would be highly desirable. Students should have a basic understanding of ERP. When they research on the Internet, students should be able to find more material they can use in their recommendations. For reference purposes, the following screens are provided: [pic] [pic] 2. Visit SCR’s data library to review SCR’s network configuration and then send Jesse a recommendation for the TIMS system architecture. She wants me to suggest an overall client/server design, number of tiers, and network topology. She also asked me to comment on these issues: legacy data, Web-centricity, scalability, security, and batch processing that might be needed. Jesse said it was OK to make reasonable assumptions in my proposal to her. Student answers will vary. Students should start by viewing the SCR network shown in the Data Library. Based on information in this chapter and previous SCR assignments, students should be able to form an opinion regarding SCR’s TIMS system. Most students will conclude that a client/server architecture should be used, and that a two-tier design probably would support SCR’s needs. With regard to network topology, not enough information...

Segmentation Using Neural Networks

...SEGMENTATION WITH NEURAL NETWORK B.Prasanna Rahul Radhakrishnan Valliammai Engineering College Valliammai Engineering College prakrish_2001@yahoo.com krish_rahul_1812@yahoo.com Abstract: Our paper work is on Segmentation by Neural networks. Neural networks computation offers a wide range of different algorithms for both unsupervised clustering (UC) and supervised classification (SC). In this paper we approached an algorithmic method that aims to combine UC and SC, where the information obtained during UC is not discarded, but is used as an initial step toward subsequent SC. Thus, the power of both image analysis strategies can be combined in an integrative computational procedure. This is achieved by applying “Hyper-BF network”. Here we worked a different procedures for the training, preprocessing and vector quantization in the application to medical image segmentation and also present the segmentation results for multispectral 3D MRI data sets of the human brain with respect to the tissue classes “ Gray matter”, “ White matter” and “ Cerebrospinal fluid”. We correlate manual and semi automatic methods with the results. Keywords: Image analysis, Hebbian learning rule, Euclidean metric, multi spectral image segmentation, contour tracing. Introduction: Segmentation can be defined as the identification of meaningful image components. It is a fundamental task in image processing providing the basis for any kind of...

Consumer Decision Making Chapter 3 INTRODUCTION TO AFFECT AND COGNITION Authors' Overview of the Chapter This is the introductory chapter on consumers' affect and cognition, and it provides a foundation for the rest of this section. Students need to understand the basic concepts presented here in order to apply them throughout the course. We begin the chapter by briefly reviewing the four elements in our basic model, the Wheel of Consumer Analysis. Then we discuss in some detail two broad, internal aspects of consumers' responses--affect and cognition. We describe affect and cognition in terms of two psychological systems that sense, interpret, and respond to information in the environment. The affective and cognitive systems can be thought of as essentially independent, yet highly interrelated modes of psychological response. Affect. Affect concerns people's feelings and emotional reactions. We identify four types of affective responses--emotions, strong feelings, moods, and evaluations--that vary in intensity and level of arousal (see Exhibit 3.2, p. 42). We emphasize that the affective system is largely...

Management Information Systems - Ups Case Study

...are the inputs, processing, and outputs of UPS's package tracking system? There are two sides to UPS's package tracking system: the external, customer-oriented side, and the internal company and employee oriented side. The input starts with customer with the creation of a scannable bar-coded “smart” label which can be done from the UPS website or using a special software provided by UPS, both accessible via the internet. These labels will contain data about the sender, the destination, and package arrival times. This data is received by UPS's central computer for processing and the information is then forwarded to one of their distribution centers where logistical planning will occur. UPS drivers are given a handheld Delivery Information Acquisition Device (DIAD) which can immediately record and upload pickup and delivery information and pictures of recipient signature to the UPS network, called UPSnet, for storing and processing. The data being sent from the DIAD is gathered from the scannable label on packages, recipient signatures captured, time card info, satellite feed of traffic patterns and changing schedules. Finally, all this information's outputs will include the UPS intranet available company-wide to distribution centers, customer service centers, etc., and the internet via UPS's website or embedded UPS functions within corporate customer's own websites. What technologies are used by UPS? How are these technologies related to UPS's business strategy? The technologies...

...A comparative analysis of Operation management of Mother Dairy and Amul Submitted by: Group 7 Sayak Ray-159 Pranaw Gautam-160 Vineet Gautam-162 Pardep Jindal-169 Monika Agarwal-170 Shruti Gupta-178 Executive Summary India’s dairy sector is expected to triple its production in the next 10 years in view of expanding potential for export to Europe and the West. Moreover with WTO regulations expected to come into force in coming years all the developed countries which are among big exporters today would have to withdraw the support and subsidy to their domestic milk products sector. Also India today is the lowest cost producer of per litre of milk in the world, at 27 cents, compared with the U.S' 63 cent. Also to take advantage of this lowest cost of milk production and increasing production in the country multinational companies are planning to expand their activities here. Some of these milk producers have already obtained quality standard certificates from the authorities. This will help them in marketing their products in foreign countries in processed form. The urban market for milk products is expected to grow at an accelerated pace of around 33% per annum to around Rs.83,500 crores by year 2010. This growth is going to come from the greater emphasis on the processed foods sector and also by increase in the conversion of milk into milk products. By 2010, the value of Indian dairy produce is expected to be Rs 10,00,000 million. Presently the market is valued at...
