...Browsers Browsers are programs that provide access to Web resources. This software connects you to remote computers, opens and transfers files, displays text and images, and provides in one tool an uncomplicated interface to the Internet and Web documents. Browsers allow you to explore, or to surf, the Web by easily moving from one Web site to another. Four wellknown browsers are Mozilla Firefox, Apple Safari, Microsoft Internet Explorer, and Google Chrome. For browsers to connect to resources, the location or address of the resources must be specified. These addresses are called uniform resource locators (URLs). All URLs have at least two basic parts. (See Figure 2-3 .) The first part presents the protocol used to connect to the resource. As we will discuss in Chapter 9, protocols are rules for exchanging data between computers. The protocol http is used for Web traffic and is the most widely used Internet protocol. The second part presents the domain name. It indicates the specific address where the resource is located. In Figure 2-3 the domain is identified as mtv.com. (Many URLs have additional parts specifying directory paths, file names, and pointers.) The last part of the domain name following the dot (.) is the top-level domain (TLD). It identifies the type of organization. For example, .com indicates a commercial site. The URL http://www.mtv.com connects your computer to a computer that provides information about MTV. Once the browser has connected...

...The browsers that I use are Google Chrome and Microsoft Internet Explorer. For this class, I mostly use Internet Explorer due to its compatibility with Blackboard vs. Chrome. At one time, I used Mozilla’s Firefox; however recently, I have found issues with the browser getting a little sluggish and decided to completely go to Chrome and save IE for when I absolutely could not use Chrome. Chrome has become a very well rounded browser from when it started. Currently, the version of Internet Explorer that I use is 9.0.8112.16421 and upon a quick check, it is the most current version. Internet Explorer 9 has anti-phishing and anti-malware functionality. In Internet Explorer 9, the functionality is called SmartScreen filter. To check if it is turned on, you click your settings (or tools) icon, scroll to safety, and click Turn off (or on) SmartScreen Filter. This will launch the tool that allows you to select whether the setting is on or off. I believe this is a great feature of Internet Explorer 9 and my SmartScreen filter is always turned on. In addition, you can double check a suspicious site if you feel that SmartScreen missed it by going to tools, safety, check this website. In addition to the SmartScreen filter, my Internet Explorer 9 browser is also set to block pop-up windows. There are a couple exceptions that I have added to the pop-up blocker which include the Pima Blackboard site and my corporate VPN site. To get to the settings for Java, I go to my Control Panel.

...Web Browser Comparison Nowadays, browsing the web is the main use of a computer. It may be searching for information, reading our emails, using the social media or even working on a cloud application. All of these functions are done with the help of an internet browser, an application that allows entering the web and gaining access to the countless webpages out there. It is therefore essential for user to know the available choices for such an important application for his daily interaction with the World Wide Web. The most popular browsers are Google Chrome, Internet Explorer, Mozilla Firefox, Opera and Safari. Even though it’s highly competitive market and new functions and improvements are quickly copied between them, still there are some differences which are worth analyzing and comparing. Google Chrome is the newest, released only in September 2008 but has already become the market leader as of September 2008. Its advantages include a very fast rendering machine and its multi-process feature that minimizes crashes as each site is run on a different process. Chrome is also recommended to users of Gmail and other Google Products as it offers some integration features. Of course, as always with Google, Chrome is strongly criticized for its non-transparent fetching of user data to the Google Databases such as auto-complete forms, browsing history raising important privacy concerns. Another browser that introduced high-speed performance is Mozilla Firefox. Its main...

...Chapter I Introduction A. Background of the Study A browser is software application that provides a way to look at and interact with all the information on the World Wide Web (Goertz, 2001). It uses HTTP to submit requests of web servers over the Internet on behalf of the browser user. Web browser is use for retrieving and presenting information resources identified by a Uniform Resource Identifier (URI) that may be video, image, web page, or other kinds of content. It can also be used to access information provided by web servers in private networks or files in file systems. There has been a virtual explosion of browsers which are designed according to their operating system and others, target specific users such as those majoring on social networking. There are also clones of established browsers such as Firefox and Google Chrome which seek to improve on the original by being “leaner” of offering different features (Anonymous, 2011). According to Bowler (2009) the browser world have spent time focusing on delivering their product to multiple OS. This helps them build many of the browsers such as Mozilla Firefox, Google Chrome, Opera, Internet Explorer and Safari. Mozilla started from scratch — Firefox was the result. And now users have no shortage of browsers to choose from, partly due to the work of the Mozilla foundation. the first full point release of Mozilla’s popular open-source Web browser in nearly three years, combines user-interface, performance and Web-standards...

...Which Browser is Best: Determining the Benefits to Each Browser Which Browser is Best: Determining the Benefits to Each Browser The purpose of this research paper is to take the reviews from users to help highlight both the positives as well as the negatives of the top four widely used Internet browsers, which will ultimately help determine which browser is the best available for consumers to use. The purpose of this study is to determine which browser is the best out of the four, and to highlight the best features from each browser, and determine their significance on how each feature is. The significance of the study is to analyze the information given on each browser and translate it into information that Internet users can take away to help them determine which browser is the best one for them between Internet Explorer, Safari, Firefox, and Chrome. The Internet has become more readily available across the globe which has caused many software developers to create their own Internet browser. In the past couple of years there has been a flood of Internet browsers available for use (Bidgoli, 2009). When the Internet was only available in select countries there was only a select number of browsers that a user could use to access the Internet. The Internet is only going to become available to more people which will most likely bring more Internet browsers to the market. There are currently millions of users that are accessing the Internet daily and each browser...

...SMash: Secure Component Model for Cross-Domain Mashups on Unmodified Browsers Frederik De Keukelaere, Sumeer Bhola, Michael Steiner, Suresh Chari, Sachiko Yoshihama {eb41704, sachikoy}@jp.ibm.com, {sbhola, msteiner, schari}@us.ibm.com IBM Tokyo Research Laboratory, Kanagawa, Japan; IBM T.J. Watson Research Center, New York, USA ABSTRACT Mashup applications mix and merge content (data and code) from multiple content providers in a user’s browser, to provide high-value web applications that can rival the user experience provided by desktop applications. Current browser security models were not designed to support such applications and they are therefore implemented with insecure workarounds. In this paper, we present a secure component model, where components are provided by different trust domains, and can interact using a communication abstraction that allows ease of specification of a security policy. We have developed an implementation of this model that works currently in all major browsers, and addresses challenges of communication integrity and frame-phishing. An evaluation of the performance of our implementation shows that this approach is not just feasible but also practical. The technology discussed in this paper allows mutually mistrusting client-side components to communicate safely without any modifications to current browsers, and hence has the potential to achieve immediate and widespread adoption.

...Harvard Business School 9-800-050 Rev. September 30, 1999 Double Dealmaking in the Browser Wars (A) For months, the upstart Netscape Communications Corporation had battled the Microsoft Corporation over which browser the accounting giant KPMG would select for its internal use. On June 2, 1997, Netscape CEO Jim Barksdale finally heard the gratifying words that capped the see-saw dealmaking process: “You've re-won the business,” said Roger Siboni, Deputy Chairman of KPMG. “And I'd like to extend my personal invitation for you to give the keynote speech at our annual meeting in Orlando, Florida.” Delighted at the news, and visualizing the army of KPMG accountants, tax people, and consultants he’d be triumphantly addressing in August, the Netscape CEO thanked Mr. Siboni, and put down the phone. This was a crucial beachhead for Netscape in its quest for the corporate market. Netscape had initially won the KPMG contract, but Microsoft’s persistence had pried it back open. Beating back Microsoft’s latest challenge marked a great success for Netscape. This victory stood in sharp contrast to a far less happy dealmaking episode the previous year in which Netscape had tilted against mighty Microsoft for AOL’s browser business. In a sequence that gave some industry observers virtual whiplash, a pathbreaking Netscape deal with AOL had been announced, only to be undercut the very next day by Microsoft. Netscape’s ultimate loss in the AOL battle helped to define an Internet dealmaking...

...Internet Technology and Web Browsers American Military University How internet technology and web browsers have affected our daily lives. Today the internet touches every corner of the globe, and often is the main way an everyday person obtains information and communicates at home, school, or place of business. We can see how internet technology affects the entire globe by just a few simple clicks of a mouse or a simple touch of a screen with in a web browser to see a webcam in the arctic to teaching school kids in India. None of this would be possible without the idea of them being able to create hardware to connect computers to share their information with one another. Local area networks, wide area networks, and metropolitan area networks are computer networks that range in different geographic sizes and functions. We use them to communicate using devices such as computers, cell phones, and game consoles. These machines have worked their way into our daily lives through the way we work, live, and play with most people not even knowing the larger impact on how they shape our lives. This concept of information passing between computers has been around since the 1960s with universities obtaining more and more computers. Then the 1970s designed the standard for implementing how computers talk to one another using the OSI model and the suite of protocols called the transmission control protocol/internet protocol (TCP/IP) was...

... 1) Basic browser buttons: The same picture is blown up twice below, so that the labels are easier to read. 2) Favorites: A favorite (or a bookmark, depending on your browser) is a link to a page that you store in your web browser. This makes it easier to pull up that page because you do not have to remember its full address, search for it, or click through links on a page to get to it. If there is a page you want to remember or like to go to a lot, you may want to add it to your favorites. Here you can see the pages that are currently saved on your computer or add a new one. 3) Home Page(s): The home page is the page or pages that the browser pulls up when you first open it. You can set it to open more than one, and you can choose what it opens first. To do this, you will want to use the “home” icon. [pic] Clicking on the icon will make the browser pull up the home page, but by clicking on the arrow immediately to the left of it, you can set a new home page. Here you can see the current home page highlighted and the options to change or remove home pages. If you choose to add or change, you will see this: You can either make the page you are currently on the home page, or tell the browser to bring it up in addition to the page(s) it is already opening. If you find that you have too many home pages, you may want to remove some, like this: 4) Help! The “help” in your browser can be found...

...Internet Browser Markets Case Summary Microsoft is the world’s largest supplier of computer software. It has dominant market share of PC operating systems with its Windows system. High barriers to entry prevent significant competition in the operating systems market. The primary barrier is that a large number of software programs must be able to interface with any operating system to make it attractive to end users. It would be extremely difficult for any competitor to create a new operating system and create or encourage the creation of completely new software to compete with Windows. However, the development of Internet Browser programs, specifically Netscape, threatened this barrier, by allowing software developers to create software that could run using the browser software as a platform for the program. Therefore, software could be created that could still be used with Microsoft Windows, but would not have to be. Microsoft recognized this development as a threat to its operating system monopoly. Initially Microsoft attempted to divide the market with Netscape, but Netscape refused. To defend its operating system, it set about to overtake Netscape with its own internet browser, Internet Explorer. To defeat Netscape, Microsoft leveraged its operating system monopoly to gain market share in the internet browser market. Microsoft forced computer manufacturers to include Internet Explorer and strongly discouraged them from including competing browsers with the...

An HTML document is a text document that contains codes, called tags, which specify how the data in the document is treated by a web browser. 886 Short Quiz 2 . In client/server architecture, what is a client? What is a server? The server is usually some sort of database from which a client requests information. A server fulfills a request for information by managing the request or serving the requested information to the client—hence the term, client/server. One of the primary roles of the client, or front end, in a two-tier system is the presentation of an interface to the user. The user interface gathers information from the user, submits it to a server, or back end, then receives, formats, and presents the results. . What does the middle tier do in a three-tier architecture? The middle tier handles the interaction between the web browser client and the data storage tier. Essentially, the client tier makes a request of a database on a web server. The processing tier performs any necessary processing or calculations based on the request from the client tier, and then reads information from or writes information to the data storage tier. The processing tier also handles the return of any information to the client...

...its products. The company contends that its actions are legal and says that there's no grounds of consumer indignation over the practices that the government is targeting. If the government wins at the trial court, it has already specified that it wants Microsoft to cancel contracts deemed exclusionary. In addition, the government wants Microsoft either to strip out its Internet browsing technology from Windows 98 or to include a rival browser made by Netscape Communications Corp. The plaintiffs alleged that Microsoft abused monopoly power on Intel-based personal computers in its handling of operating system sales and web browser sales. The issue central to the case was whether Microsoft was allowed to bundle its flagship Internet Explorer (IE) web browser software with its Microsoft Windows operating system. Bundling them together is alleged to have been responsible for Microsoft's victory in the browser wars as every Windows user had a copy of Internet Explorer. It was further alleged that this restricted the market for competing web browsers (such as Netscape...
