Application software directly performs tasks for the user like writing letters, creating presentations, or playing DVDs, in contrast to system software which integrates the computer's capabilities without directly applying them. Application software refers both to the program itself and its implementation. It is generally the primary reason users turn on their computer in the first place to complete tasks like writing or watching videos. The homework questions from pages 235-237 of the book should be completed and uploaded since school internet access may be unreliable over the break due to maintenance.
Application software comes in many forms, including packaged, custom, web-based, open source, shareware, and freeware. It can be categorized based on its purpose, such as business software, graphics/multimedia software, home/personal software, and communication software. Web 2.0 refers to websites offering web-based software, allowing users to interact and collaborate online. Application service providers (ASPs) manage and distribute software applications via the web. Learning tools like help files, templates, and online training help users support application software.
Cost benefit analysis (CBA) determines the costs and benefits of a proposed project or policy. It has its origins in the 19th century and was established in US law in 1936. CBA is used to assess whether a project is economically feasible, which of multiple options provides the best return, and the optimal timing. It involves identifying costs like financial outlays and environmental impacts, and benefits like increased productivity or time savings. Alternatives are compared by weighing total benefits against total costs. CBA can be used to analyze options for reducing traffic congestion in Dubai by considering costs and benefits of policies, infrastructure projects, and public transport improvements.

This document discusses corrosion control engineering for gas pipelines. Corrosion causes degradation of pipeline materials over time. Two main methods for mitigating corrosion are protective coatings and cathodic protection using sacrificial anodes. Various tests are performed on coating materials to evaluate properties like strength, density, and volatile content. Proper coating selection and corrosion protection techniques can help minimize corrosion and extend pipeline lifespan, but factors like material type, location, and costs must be considered. The goal is to harness the adverse effects of corrosion to safely deliver gas to customers.
This document discusses corrosion control engineering and summarizes various techniques used to mitigate corrosion in gas pipelines. It describes how corrosion occurs via electrochemical reactions between the pipe material and the surrounding environment. Common mitigation methods used by SNGPL include protective coatings and cathodic protection using sacrificial anodes. The document then summarizes various tests and equipment used to inspect coatings, such as tests to evaluate properties of primers, coatings, and anodes used in corrosion protection systems.
