Web traffic is doubling every year, according to recent global studies. The user needs more information from Web sites and wants to spend as little time for downloading as possible. Simultaneously, more Internet bandwidth is needed and all ISPs are trying to build high bandwidth networks. This paper presents a case study that calculates the reduction of the time needed for a Web page to be fully downloaded and delivered to the user. Presents a way to calculate the reduction of data transfer, bandwidth resources and response time when the HTTP/1.1's compressing feature is enabled (either in plain hypertext files or the text output of CGI programs or dynamically generated pages). Measurements are taken from five popular Web sites in order to validate our statement for reduction in transfer time. The definition of the mean size of a Web page that commercial Web sites have is additionally in the scope of this paper.
The growth of networked systems has magnified the use of raw resources such as images, animations, videos, etc. The networking facilities between different systems and the lack of security between them have introduced the need for image, animation and video copyright protection. One approach used to address this problem is the use of structure that can seal or mark any digital material. These structures are called watermarks. In this paper, we present different solutions, commercial, freeware or scientific, for the marking of multimedia objects.
Considers the problem of improving the performance of Web access by proposing a reconstruction of the internal link structure of a Web site in order to match the quality of the pages (measured in terms of their link importance in the Web space ± global ranking) with the popularity of the pages (measured in terms of their importance recognized by Web users ± local metrics). Provides a set of simple algorithms for local reorganization of a Web site, which results in improving users' access to quality pages in an easy and quick way.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
