The Theory Aspects of Website Development

Introduction

Search engines are programs which are designed to fetch documents from file transfer protocol and the World Wide Web through the application of keywords that are supplied by the user. Upon successful fetching, these programs return lists of documents that contain much of the supplied keywords so as to enable the user to choose the most appropriate information. Although the phrase makes a general reference to the category of programs that fetch documents on the web, most users associate it with systems such as Google, Excite, and Alta Vista. The engines operate by fetching several documents before arranging them on the basis of the phrases they contain. The arrangement of documents is facilitates by another program which is referred to as an indexer. Every search engine creates indices through a proprietary algorithm, a situation that enables it to present meaningful results to the user. Search engine result pages may contain text and images, as well as other varieties of files. This paper compares two search engines, Google and Bing, in terms of performance and search technology.

Performance and Search Technology

Google Web Search refers to is a search engine which is owned by Google Inc. as the most utilized search engine Google services facilitates millions of web queries every day. Its search results are ranked as par their priority according to what is referred to as Page Rank. Google Web Search presents a variety of options for its customized search. For instance, there are options that utilize Boolean operators like exclusion, alternatives, and wildcard. The primary utility of Google Web Search is to fetch for text from the Web pages. Nevertheless, the program incorporates over 22 features that facilitate roles which are beyond its original word-based search capabilities. The features include weather forecast, stock quotes, time zones, maps, sport scores, and earthquake data. Additionally, it incorporates exceptional features temperatures, language translations, calculations, patent area codes, money/units conversion as well as prices. These features make Google superior to other search engines especially because it has the capacity to indicate broader social, health, and economic trends.

Bing is a web-based search engine that is designed by Microsoft. The tool was unveiled in May 2009 and became fully online in June 2009. Before it was unveiled, Microsoft made a number of enhancements so as to make Bing operate better than MSN Search. Enhancements included the possibility of listing suggestions while queries are being entered so as to enable the user to select a suggestion from the explorer pane. This was achieved by utilizing semantic technologies such as Powerset. Since October 2011, the tool has been presented with a back-end searching infrastructure, a provision that enhances the speed of delivery of results. Bing has also been incorporating an index-serving technology since August 2011. These enhancements have enabled Bing to increase its market share, as indicated by Appendix A.

Interactivity of Web Pages

Interactivity of the web pages refers to the facility that allows users to navigate over related web contents. In this case, users can perform varied actions with relation to the web contents they are utilizing. Interactivity is facilitated by technologies, such as Dynamic Hyper-Text Markup Language, DHTML, and Extensible Markup Language, XML. DHTML refers to an aggregation of technologies that are utilized together during the creation and animation of web pages. It utilizes a set of the static markup language like HTML, a client-side scripting language, presentation definition languages, and Document Object Models. DHTML enables scripting languages to alter variables on page definitions, especially after the completion of page loading. This, therefore, enhances functionality during the utilization of pages. Google utilizes DHTML in fathoming the user’s intent. For instance, Google enables users to detect Spamming by availing content with JS/CSS OFF. As such, if the user finds that he cannot make content visible after hiding, Google facilitates the interpretation of such a scenario as Spamming.

Extensible Markup Language, XML, refer to a set of rules that are followed during encoding of documents into a format that facilitates human as well as machine readability. XML’s design emphasizes generality, usability, and simplicity while using the internet. It achieves these design goals through Unicode, a functionality that supports natural languages. In addition to documents, XML focuses on the presentation of web services and other arbitrary data structures. Software developers utilize interfaces in application programs so as to enable definition of a variety of XML based languages.

Web Security

Enterprises utilize the internet during their day-to-day communications. Moreover, the internet facilitates research and evaluation of the manner in which events and trends affect business practices. However, increased use of the internet presents networks with the risks of viruses and malware. These risks have the potential to cripple the company through compromising the data, disabling computers, and crashing the entire network. Other security risks involve hacking of the computer system. At times, hacking has proved to be more dangerous than other forms of insecurity as the hacker may utilize the data as he wishes. In 2009, hackers attacked computer systems belonging to Ballard High School with the intention of altering grades. Such attacks have taken place in many other institutions of learning. Ultimately, they result in massive losses to the institutions affected, and in some instances, the damage is never redressed in totality.

Security may be enhanced through scanning of inbound as well as outbound traffic so as to facilitate the stopping of viruses, malwares, and other dangerous programs before they enter the network. Although internet access is difficult to control, an enterprise can control contents that find their way into its computer systems. Web filtering facilitates the creation, enforcing, and monitoring of online computer usage. It enables an organization to allow access to useful sites, while blocking sites that are presumed to be popular with hackers.

Evolution of the Internet

The term Internet refers to a worldwide system of interconnected computer networks. This interconnection uses standard protocols like the Internet Protocol Suite to enable it serves people in all nations of the world. The Internet is a “network of networks” that comprises numerous government, business, academic, public, and private networks. These networks are connected through an extensive array of optical, wireless, and electronic networking technologies.

The internet is evolving into an avenue for wide-scale communication and easy accessibility. With the enhanced communication capabilities, the internet will help improve multimedia based marketing strategies. The boundless communication possibility it provides, assures its future usefulness in education and research. It will avail vast contents of information to students, government agencies, and any other person who may require exploring and researching on an issue. Access to such vast amounts of information through any other mean would be inhibited by the cost that a person may have to incur. It will be easy to evaluate, ascertain, and compare the sources and the contents of such information. This is because one will not have to search volumes of books in a library. Furthermore, institutions, government agencies, and individuals will be able to exchange information over the internet with ease. This mutual information exchange will lessen the time taken when conducting research and preparing reports.
