Abstract

In modern computing, multitasking is the most favorable aspect. An un-pipelined instruction cycle (fetch-execute cycle) CPU processes instructions one after another increasing duration at lesser speed in completing tasks. With pipelined computer architecture, unprecedented improvement in size and speed are achievable. This work investigates the possibility of a better improvement to computer architecture through understanding the inner workings of instruction pipelining in operating system. A design of a 5 stage pipelined architecture simulator for RiSC-16 processors using Visual Basic programming has been achieved contrary to the common available four stage simulators. The simulator also future two most common pipeline instruction hazards generally missing in most available simulators. Thus, the designed simulator becomes an appropriate tool for understanding the concept of pipelining on a step-by-step visualization based instructioncycle processors hence facilitating a more efficient design in computer architecture. The simulator has been evaluated based on its closeness to real time pipelined computer architecture and through execution of all 8 basic RiSC-16 instruction set with data dependency and control hazard.

Abstract

Objectives: This paper is aimed at investigating and increasing awareness about various concepts related to Electronic Payment Systems (EPS) including its advantages, challenges and security considerations. The proposed study also evaluates the adoption of e-payment systems and the resulting impact on economy of a nation. Methods/Statistical Analysis: In this paper, a comprehensive survey on all the aspects of electronic payment was conducted after analysis of several research studies on online payment systems. The most recent references and information have been explored in order to gain significant information about electronic payments systems. Findings: From the study conducted, it can be elucidated that despite various issues that usage of electronic payment systems pose, these are identified as a positive step towards the economic development of a nation. Nevertheless, its full potential can be realized only by raising its awareness among people. Applications/Improvements: With the advancement in technology and popularity of Internet, the perception of making online transactions is bound to gain momentum. In the future, the payment modes currently used and supported shall see a declining trend owing to the numerous benefits offered by electronic payment systems.

Abstract

Objectives: The goal of this paper is to comprehend the significance of adopting Cloud Computing (CC) in establishments of higher learning. This paper plots a portion of the advantages that can be conveyed to advanced education by means of cloud computing, analyzes probably the most imperative difficulties that can be faced by the academia due to its adoption, and proposes some early strides towards its adoption while alleviating the risks involved. Methods/Statistical Analysis: This paper recognizes an expansiveness of institutional variables and CC appropriation procedures by including the diverse perspectives of sources from various backgrounds and contexts on a single phenomenon. The different aids and contributions in this paper are based on the consolidation of research works available in different papers. Findings: The discoveries from this analysis demonstrate that the adoption of CC in establishments of higher learning can be comprehended through a few factors that have an essential impact on CC adoption methodologies like administrative bodies and governments, internal stakeholders, cloud suppliers, firm attributes, socio-political changes, IT framework, and so on. Applications/Improvements: This investigation offers open doors for future research besides giving an understanding into how cloud suppliers, advisors, governments, and scholastics see diverse market requests, and how they react to these requests while advancing services offered by CC in higher learning institutions. The consequences for practice can help decision makers in adopting services offered by CC legitimately.

Abstract

Objectives: This paper discusses the proposed system which provides the user the ability to run the application on Android phones for encrypting all types of files before they are stored. Methods/Statistical Analysis: In the proposed system, Advanced Encryption Standard (AES) is employed for encryption as well as decryption of the files stored by users in mobile phones. All types of files including docx, text, pdf, image, ppt, audio and video files can be encrypted and later regenerated as well. Findings: The use of AES in encrypting and decrypting data in this system provides good security as well as higher speed. An added advantage is that it is implementable on several platforms particularly in small gadgets like smartphones. As compared to the traditional computers, smartphones can be carried more easily and provide similar functionalities as that of a computer like data storage and processing, communication and other services including video call, wireless network, web browser, GPS, audio or video player. Application/Improvements: Data is transmitted, shared and stored for various purposes including production, banking, development, and research. Therefore, security is a must for information which can be provided by encryption using AES as proposed in this system.
