* What are the main differences between a GIF and a JPEG file? Both the GIF and JPEG are compression formats for storing images to be displayed electronically. The JPEG format can display literally millions of colors and is frequently used for displaying images such as photos‚ artwork‚ or intricate designs. A GIF only displays up to 256 colors and because of that is more apt to be used for more simple images such as cartoons‚ or word based items. GIFs also have a faster load time because of the

A waterfall is a point where there is an interruption in the river profile and the water makes a vertical drop. It is normally found in the upper stage of the river. Aasleagh falls near Killary harbour and torc waterfall county Kerry are well known waterfalls in Ireland. Most waterfalls develop where the river meets a band of softer‚ less resistant rock after flowing over harder more resistant rock. As a result of differential erosion the water quickly erodes the softer rock by the processes of

social development has been diluted. Nevertheless‚ over the years it has become obvious that entrepreneurship has grown in importance and that it indeed contributes to economic well being. Converting ideas into successful economic opportunities is the main essence of entrepreneurship. If we cast an eye over the past‚ the economic momentum has been substantially advanced by pragmatic individuals who are creative and innovative‚ able to utilize opportunities and willing to take risks. Whatever the definition

A waterfall is a feature of erosion found in the youth stage of a river. Waterfalls are found in areas with bands of hard and soft rock (otherwise known as resistant and less resistant rocks). The hard rock takes longer to erode than the soft rock (differential erosion) so the river erodes the land at different rates. The river erodes the soft rock by the main processes of erosion including Hydraulic Action (the force and power of the moving river) and Abrasion (the scraping of the load against

Introduction The waterfall model is the most common model of all software development life cycle models. It is very simple to understand and use. In a waterfall model‚ each phase must be completed before the next phase can start. At the end of each phase‚ a review takes place to determine if the project is on the right path and whether or not the project should be continued. Here phases do not overlap with each other. Waterfall model is a sequential design process in which progress is seen

Abstract: Agile methods in recent years have emerged as a new paradigm in software development‚ which promises to address some of the problem areas of traditional approaches by freeing some of its constraints. In an attempt to produce an improvised process to designing and implementation and thereby to produce qualitative deliverables‚ several pioneering efforts have been suggested. This paper examines two such methodologies that promote agility: eXtreme Programming and SCRUM. The process‚ the

SDLC Process Renee Fowler Systems Analysis and Design/BSA/376 August 20‚ 2012 Deborah J. Marshall SDLC Process The system development life cycle (SDLC) starts when a project is planned for the implementation of an information system. Executives of the organization make a decision for a new system or replacing or upgrading an old system and the project begins. According to Curry‚ McGregor‚ and Tracy (2007)‚ “For a development project to be successful‚ the people involved in the project

For application development‚ numerous guidelines or best practices are available to emphasize the importance of secure coding practices. Introducing security into the SDLC A key component of the software development life cycle is verifying that application is secure. Tests of an application’s security can happen in any phase of the SDLC. However‚ in the alpha and beta phases‚ there should be constant security testing. Key areas that must be considered as part of overall security vulnerability testing

SDLC Value PaperThe Systems Development Life Cycle (SDLC) is the process of building‚ deploying‚ using‚ and updating of an information systems (Satzinger‚ Jackson‚ & Burd‚ 2009). Organizations use a variety of information systems to support the processes that are used to carry out the operation and functions of the business. In order for a project to be successful‚ the developers of the system should have a plan to follow that is organized. This report will explain the components of a formal
