2. An easy to operate user friendly, economically priced software that Committed to meet the all requirements. Download Accelerator is a light-weight, powerful and easy-to-use application. It is designed for downloading files and whole web sites from any remote server via HTTP. Download Accelerator makes it possible to avoid many problems related to downloading: Modules: 1. Download: Downloads - here you can find and manage your current downloads. You can manage queues, schedules and progress. Here you have to specify the located file URL. The download will start and a window displaying information about the file currently being downloaded will appear. In download window you can keep multiple downloads on one screen, save a download to a specific folder or location. If we are downloading file via proxy server, we have to specify the username, password and proxy server address. Once the file starts downloading it will shows on status bar. 2. Completed Downloads: Completed Downloads' - here you can view your completed downloads history, access Downloaded files or re-downloaded files i.e. resuming files which not completed its downloading process. In Download module we specifies the location where the file to be saved by saying Save To field.

3. The previous system was download files through internet explorer. In the existing system process we cannot pause the download process. The previous system does not use the complete bandwidth as the bandwidth is get shared for browsing the web pages.

4. Downloading files over the network could be a cumbersome task. Trying to implement other features like auto-resume and support for proxy servers, etc. makes it even harder. Using this component can make things a lot easier for you. You can download files over proxies, password protected sites or untrusted SSL connections simply by setting a few properties. The example that is provided shows how to do the job and how to handle events over a simple GUI.

17. Testing Software testing is a critical element of software quality assurance and represents the ultimate review of specification, design and coding. In fact, testing is the one step in the software engineering process that could be viewed as destructive rather than constructive.
