本文是计算机专业的留学生作业范例，题目是“The Web Browser Comparison Computer Science Essay（网络浏览器比较计算机科学论文）”，在这个作业中，我将讨论网络浏览器之间的比较。首先，到底什么是网络浏览器。实际上，它是一个软件应用程序，用于检索、展示和遍历万维网上的信息资源。不仅如此，它还可以定义为一种应用软件或程序，旨在使用户能够访问、检索和查看Internet上的文档和其他资源。
In this assignment, I am going to discuss about the comparison between web browsers. First, what is a web browser exactly. Actually it is a software application for retrieving, presenting and traversing information resources on the World Wide Web. Not only that, it can be also defined as an application software or program designed to enable users to access, retrieve and view documents and other resources on the Internet.
Internet has enormous of information. We can find out any information in internet. By going to the internet, we require web browser to show us the information such as text, image, video, sound and graphic. Web browser would arrange the information well and present to user in an orderly manner. Browsers are primarily planned to use the World Wide Web, however they can also be used to access information provided by web servers in private networks or files in file systems. The major web browsers are Google Chrome, Firefox, Internet Explorer, Opera, and Safari.
In 1991, the first web browser was released by Sir Tim Berners-Lee. It was named WorldWideWeb and was later renamed to Nexus to avoid confusion with www system. It was the first graphical web browser and WYSIWTG HTML editor.
1991年，Sir Tim Berners-Lee发布了第一个网络浏览器。它被命名为WorldWideWeb，后来改名为Nexus，以避免与www系统混淆。它是第一个图形化的web浏览器和WYSIWTG HTML编辑器。
In 1993, browser software was further revolutionized by Marc Andreessen and with the release of Mosaic (later Netscape), It is the world’s first popular browser which made the World Wide Web system easy to use and more accessible to the typical person. The introduction of Mosaic became one of the first graphical web browsers which led to an explosion in web use. Andreessen who the leader of the Mosaic team at NCSA has soon started his own company, named Netscape, and released the Mosaic-influenced Netscape Navigator in 1994, which rapidly became the world’s most common browser, accounting for 90% of all web use at its peak.
In 1995, Microsoft responded the release of Navigator with its own browser, called Internet Explorer. It is heavily influenced by Mosaic, initiating the industry’s first browser war. Then, Internet Explorer gained dominance in the web browser market; Internet Explorer usage share peaked at over 95% by 2002.
The objective of this research is to determine the advantage within web browsers. Nowadays, there are countless of web browser software application is available to every one of online users. The most major web browsers are Google Chrome, Firefox, and Internet Explorer. As it has too much of web browsers is available, I only choose to discuss about the 3 major web browsers which I mention above. There are many factors affect users to determine which of the browsers they choose use.
Among those factors, I have chosen 5 of them to discuss. First is Feature. A web browser should offer useful, convenient features that make surfing the web easier and faster. For example, a browser should provide tabbed browsing, an integrated search engine and customizable toolbar. For a more humanize web experience, the browser should also provide the ability to save bookmarks, set parental controls and create RSS (Rich Site Summary) feeds. Generally speaking, the more features an internet browser provides, the better. The second is Security.
While online security measures have come a long way since the beginning of the internet, the web is still widespread with security risks to hack our electronic data. Security features like privacy settings, pop-up blocker and antispyware enable security on internet and help keep private information such as passwords secure. The third factor is Speed and Compatibility. Web browsers should load fast and be well-suited with all major operating systems. A top internet browser will load between pages within only a few seconds.
Fourth factor is Ease of Use. The best internet browsers are those that have a smooth balance between features and ease of use. While features on a web browser are important, they become valueless if a browser’s interface hinders your capability to use them. The last factor is Help and Support. Although some internet browsers are open source and therefore not enhanced with dedicated technical support, I still considered the quality of support options available. When it comes to internet browsers, available support can come in many forms, from FAQs to tutorials, email support to a product manual.
3.Internet Explorer IE浏览器
Internet Explorer has offers several features to improve browsing. The browser uses tabs and when you open a new one, it suggests links based on your previous browsing history. The browser also has a box for both searching and website addresses as well as full combination with Windows 7. For instance, you can make what the browser calls a jump list which is the list of your most frequently visited websites pinned to your taskbar. In the same way, you can select an individual tab and drag it to your toolbar.
There are four different categories of add-ons provided by Internet Explorer: security, time savers, browsers and entertainment. You will find a number of downloads in each category, each with a description. Major are free, but some you will have to purchase.
However, internet browser does not have spell check and integrated download manager, therefore downloads will appear in a pop-up window. And different to some of the other internet browsers we studied, Internet Explorer is not open-source. Open source means the software is made and maintained by a network of users. The coding is made available to everyone, and volunteer software programmers are encouraged to improve it.
4.Google Chrome 谷歌浏览器
Chrome is made to keep you harmless and more secure on the web with built-in malware and phishing protection. Chrome also has auto-updates feature to confirm you have all the latest security fixes, and more. When you navigate to a website suspected of phishing or containing malware, the internet browser displays a warning.
The browser also has auto-updates to make sure your security features stay current without any action on your part, and it applies the sandboxing method. Sandboxing is software that helps block malware and isolates what happens in one tab from affecting the others, so once you close a tab, that process is absolutely ended. Sandboxing is an effective method for stopping malware from installing itself on your computer and monitoring your online activities.
5.Mozilla Firefox 火狐浏览器
Firefox has integrated private browsing. You can simply enable and disable the private mode. Furthermore, different from other browser privacy modes, there is no visible icon on the interface when in private mode. Mozilla Firefox protects against viruses, malware, spyware and phishing sites as well as pop-ups. Automatic updates are also available, so your browser is always up-to-date on the latest security fixes. You also can modify your security settings and control the level of security placed on sites and customize settings for cookies, downloads, passwords and add-ons.
An additional impressive security feature the internet browser owns is the one-click site info. You can simply click on the site in the address bar to view important safety information. You can simply delete your personal information, including history, cookies, passwords and web-form entries with the click of a button. Remove all traces of visited website is also available.
6.Help & Support 帮助和支持
Google Chrome has an in-depth help center that offers support in all sorts of categories. A lot of resources are provided by help center to help new users started, and advanced users fully customize their browsing experience. Help forum is there provided by Google where users can post issues and interacts with other users as well as giving useful feedback for other users who experiencing same issues.
As usual, a lot of useful online documentation, including FAQs, a knowledgebase and a tutorial is provided by Mozilla. The knowledgebase is searchable and consist of standard help. Not only that, there is also personalized help which in the form of live chat with the Firefox community. Direct support via email is also available.
Internet Explorer has the best help and support while reviewing internet browsers. On its website, you would find in-depth documentation, tutorials and FAQs. You can simply search the online resources by keyword. Internet Explorer is also one of the only internet browsers that is enhanced with direct technical support. Personal assistance via email and telephone are provided by Microsoft.
In my conclusion, there is always some difference between these several browsers. However, each browser has strengths and weaknesses. There is hardly to find a perfect and seamless web browser. Google Chrome, Mozilla Firefox and Internet Explorer all have its good and bad. Most of us here are preferred using Google Chrome, it is because, compare to Firefox 4 and IE9, it was unquestionably the fastest browser. Though Chrome is now leading the web browser, IE and Firefox also have strengthened its performance and offering new features that benefit and contribute to users.For the long term, we could not claim a strong victor here as all three major browsers provide a solid browsing experience with few downsides. Things are heating up in the browser world.
