System permissions are divided into several protection levels. The two most important protection levels to know about are normal and dangerous permissions: Normal permissions cover areas where your app needs to access data or resources outside the app's sandbox, but where there's very little risk to the user's privacy or the operation of other apps. For example, permission to set the time zone is a normal permission. If an app declares that it needs a normal permission, the system automatically grants the permission to the app. For a full listing of the current normal permissions, see Normal permissions . Dangerous permissions cover areas where the app wants data or resources that involve the user's private information, or could potentially affect the user's stored data or the operation of other apps. For example, the ability to read the user's contacts is a dangerous permission. If an app declares that it needs a dangerous permission, the user has to explic...

             Introduction to Applied Statistics Applied Statistics is a branch of applied mathematics concerned with the collection and interpretation of quantitative data and the use of probability theory to estimate population parameters. In applying statistics such as a scientific, industrial, or societal problem, it is necessary to begin with a population or process to be studied. Populations can be diverse topics such as "all persons living in a country" or "every atom composing a crystal". It deals with all aspects of data including the planning of data collection in terms of the design of surveys and experiments.                    Software Environment The S, S plus, Mat lab and R environments are an integrated suite of software facilities for data analysis and graphical display with the feature like an extensive and coherent collection of tools for statistics and data analysis, language...

  Multimedia Team ( Project manager, Multimedia Designer, Interface Designer, Writer, Video Specialist, Audio Specialist, Multimedia Programmer, The Sum Of the parts ). A typical team for developing multimedia for CD-ROM or the Web consists of people who bring various capabilities to the table. Often, individual members of multimedia production teams wear several hats. 1.       Project Manager: A project manager’s role is at the center of the action. He or she is responsible for overall development and implementation of a project as well as for day-to-day operations. Budgets, schedules, creative sessions, time sheets, illness, invoices, team dynamics-the project manager is the glue that holds it together.                         2.       Multimedia Designer : Multimedia designers need variety of skills. We...

  THE STAGES OF PROJECT :   Most multimedia and Web projects must be undertaken in stages. Some stages should be completed before other stages begin, and some stages may be skipped or combined. Here are the four basic stages in a multimedia project. Planning and costing : A project always begins with an idea or need that we refine by outlining its messages and objective. Before we begin developing, plan what writing skills, graphic art, music, video, and other multimedia expertise will be required. Develop a creative graphic look and feel, as well as  a structure and navigation system that will let the viewer visit the messages and content, estimate the time needed to do all elements, and prepare a budget. Work up a short prototype or proof of concept  Designing and Producing :  The major goal of this phase is to translate the problem studied in the first phase and design made in second phase into proper a finishe...

Multimedia: Multimedia is any combination of text, graphic art, sound, animation, and video delivered to you by computer or other electronic means. It is richly presented sensation. When you weave together the sensual  elements of multimedia-dazzling pictures and animations, engaging sounds, compelling video clips, and raw textual information, you can electrify the thought and action centers of people’s minds.  When we allow an end user – the viewer of a multimedia project-to controls what and when the elements are delivered, it is interactive multimedia.   Its applications :  Multimedia is appropriate whenever a human interface connects a human user to electronic information of any kind. Multimedia enhances minimalist text-only computer interfaces and yields measurable benefit by gaining and holding attention and interest, multimedia improves information retention. There are following areas where multimedia is being used. 1. Multimedia in Business : Bu...

THE RISK DRIVEN MODEL - Introduction As digital systems become part of everyday life for most of us that caused increase in the development of software systems and applications hugely. The increasing number also shows the worries of developers for risk of failure for different stages of the development and different platforms including web. The management of risk is very important factor to be considered for all software development processes. The risk driven model is very simple and easy to use with having low “risk of failure” level which attracts most of the developers. However, the development of software means developer must anticipate the possible risk of failure for different stages by using right tools and techniques. Though which development technique is more reliable? Or which architecture is enough for developer? And which is model should developer use is still a question. So here I present how risk driven is enough for the developers for all stages (including an...
