The way in which the displaying of the web pages is done within a search is not a mystery. It involves applied math and good computer science knowledge for the right implementation. This relation involves vectors, matrixes and other mathematical notations. The PageRank vector needs to be calculated, that implies calculations for a stationary distribution, stochastic matrix. The matrices hold the link structure and the guidance of the web surfer. As links are added every day, and the number of websites goes beyond billions, the modification of the web link's structure in the web affects the PageRank. In order to make this work, search algorithms need improvements. Problems and misbehaviors may come into place, but this topic pays attention to many researches which do improvements day by day. Even though it is a simple formula, PageRank runs a successful business. PageRank may be considered as the right example where applied math and computer knowledge can be fitted together.
World Wide Web has become a global driver in the information sharing from the users. Internet has changed a lot during its lifetime. The change is continuing with the rise of new technologies as well. The low cost wireless connections are making the information sharing even more persistent. Data collection has become more advanced with embedded devices connected with each other and RIFD technology used to transmit data in a continuous way. Exactly these technologies has led to the “Internet of Things” that is a way to display web as a medium of connected devices through the world and to communicate with each other. IoT has also faced a lot of challenges, especially when it comes to Enterprise IoT. Techniques for implementing IoT need to be developed especially in developing countries. The challenges and threats of the IoT are described in this paper. An initial security evaluation is also shown.
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.
