...operations based on the information that is stored. Peripheral devices allow information to be entered from external source, and allow the results of operations to be sent out. A computer's processing unit executes series of instructions that make it read, manipulate and then store data. Conditional instructions change the sequence of instructions as a function of the current state of the machine or its environment. The first electronic computers were developed in the mid-20th century (1940–1945). Originally, they were the size of a large room, consuming as much power as several hundred modern personal computers (PCs).[1] Modern computers based on integrated circuits are millions to billions of times more capable than the early machines, and occupy a fraction of the space.[2] Simple computers are small enough to fit into mobile devices, and can be powered by a small battery. Personal computers in their various forms are icons of the Information Age and are what most people think of as "computers". However, the embedded computers found in many devices from MP3 players to fighter aircraft and from toys to industrial robots are the most numerous. History of computing Main article:...

...ASP.Net What is view state and use of it? The current property settings of an ASP.NET page and those of any ASP.NET server controls contained within the page. ASP.NET can detect when a form is requested for the first time versus when the form is posted (sent to the server), which allows you to program accordingly. What are user controls and custom controls? Custom controls: A control authored by a user or a third-party software vendor that does not belong to the .NET Framework class library. This is a generic term that includes user controls. A custom server control is used in Web Forms (ASP.NET pages). A custom client control is used in Windows Forms applications. User Controls: In ASP.NET: A user-authored server control that enables an ASP.NET page to be re-used as a server control. An ASP.NET user control is authored declaratively and persisted as a text file with an .ascx extension. The ASP.NET page framework compiles a user control on the fly to a class that derives from the System.Web.UI.UserControl class. What are the validation controls? A set of server controls included with ASP.NET that test user input in HTML and Web server controls for programmer-defined requirements. Validation controls perform input checking in server code. If the user is working with a browser that supports DHTML, the validation controls can also perform validation using client script. What's the difference between Response.Write() and Response.Output.Write()...

...Year 11 Computer Education syllabus trialed in Fiji secondary school for the year 2014. It is a new text book and the first of its kind to be written locally. It is hoped that this book will be useful in implementing the syllabus but it should be understood that it is not the syllabus. The syllabus is the framework for the teacher to follow while this text book is a resource for the student. Therefore departure to other resource materials for more information will be acceptable. The text book is not the perfect piece of work as it has been prepared in a very short time, therefore suggestions for amendments will be welcomed. It is anticipated that this book will minimize the amount of time for teachers in lesson preparation and more time will be devoted to actual classroom teaching and learning. There may be a variety of opinion about the content of the topics, but for the beginner it is the best which gives the time and opportunity to become familiar with the basics before pursuing further into the field of study in greater detail at the upper secondary level Ministry of Education, Suva.

...emerging topics in CS research or the impact of papers on the field. In contrast, in this article, we take a closer look at the entire CS research in the past two decades by analyzing the data on publications in the ACM Digital Library and IEEE Xplore, and the grants awarded by the National Science Foundation (NSF). We identify trends, bursty topics, and interesting inter-relationships between NSF awards and CS publications, finding, for example, that if an uncommonly high frequency of a specific topic is observed in publications, the funding for this topic is usually increased. We also analyze CS researchers and communities, finding that only a small fraction of authors attribute their work to the same research area for a long period of time, reflecting for instance the emphasis on novelty (use of new keywords) and typical academic research teams (with core faculty and more rapid turnover of students and postdocs). Finally, our work highlights the dynamic research landscape in CS, with its focus constantly moving to new challenges arising from new technological developments. Computer science is atypical science in that its universe evolves quickly, with a speed that is unprecedented even for engineers. Naturally, researchers follow the evolution of their artifacts by adjusting their research interests. We want to capture this vibrant co-evolution in this paper. 1 Introduction...

...INTRODUCTION AND BACKGROUND Today, in order to efficiently and effectively deal with data confidentiality and system security, organizations must adopt an approach that is both holistic and proactive. This decision traditionally involves an evaluation of the business processes involved, assessment of compliance with regulations and standards, and the identification of information systems and technology capability. Cloud Computing has become one of the most discussed and sought after solutions for dealing with such challenges. According to IDC Cloud, research suggests that IT Cloud Services spending will reach $47.4 billion in 2013 and is expected to be more than $107 billion in 2017 with an annual growth rate of 23.5 percent, five times that of the industry (IDC, 2013). Cloud Computing is a resourceful model that allows enterprises to accelerate innovation, decrease infrastructure costs, improve resource utilization, and greater ability to manage information technology security (PwC, 2010). The “Cloud” refers to the Internet, a collection of interconnected networks that communicate with each other, and it can be accessed globally. Cloud Computing employs network resources to deliver services entirely online. The National Institute of Standards and Technology defines Cloud Computing as: “A model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services)...
