The Internet Explorer project
864-519: A feature to cloak or spoof their identification to force certain server-side content. For example, the Android browser identifies itself as Safari (among other things) in order to aid compatibility. Other HTTP client programs, like download managers and offline browsers , often have the ability to change the user agent string. A result of user agent spoofing may be that collected statistics of Web browser usage are inaccurate. User agent sniffing
960-498: A lawsuit and a US$ 8 million settlement on January 22, 1997. Microsoft was sued by SyNet Inc. in 1996, for trademark infringement , claiming it owned the rights to the name "Internet Explorer". It ended with Microsoft paying $ 5 million to settle the lawsuit.

Frequently used development tools such as compilers , linkers , and debuggers are classified as system software. System software and middleware manage and integrate
2496-476: Is denoted CMOS-integrated nanophotonics (CINP). One benefit of optical interconnects is that motherboards, which formerly required a certain kind of system on a chip (SoC), can now move formerly dedicated memory and network controllers off the motherboards, spreading the controllers out onto the rack. This allows standardization of backplane interconnects and motherboards for multiple types of SoCs, which allows more timely upgrades of CPUs. Another field of research
2592-485: Is intimately tied to the representation of numbers, though mathematical concepts necessary for computing existed before numeral systems . The earliest known tool for use in computation is the abacus , and it is thought to have been invented in Babylon circa between 2700 and 2300 BC. Abaci, of a more modern design, are still used as calculation tools today. The first recorded proposal for using digital electronics in computing
2688-710: Is its potential to support energy efficiency. Allowing thousands of instances of computation to occur on one single machine instead of thousands of individual machines could help save energy. It could also ease the transition to renewable energy source, since it would suffice to power one server farm with renewable energy, rather than millions of homes and offices. However, this centralized computing model poses several challenges, especially in security and privacy. Current legislation does not sufficiently protect users from companies mishandling their data on company servers. This suggests potential for further legislative regulations on cloud computing and tech companies. Quantum computing
2784-442: Is listed first. The parts of this string are as follows: During the first browser war , many web servers were configured to send web pages that required advanced features, including frames , to clients that were identified as some version of Mozilla only. Other browsers were considered to be older products such as Mosaic , Cello , or Samba , and would be sent a bare bones HTML document. For this reason, most Web browsers use
2880-559: Is sometimes considered a sub-discipline of electrical engineering , telecommunications, computer science , information technology, or computer engineering , since it relies upon the theoretical and practical application of these disciplines.

A frame process can create multiple tab processes, each of which can be of
User-Agent header - Misplaced Pages Continue
4032-481: The Temporary Internet Files folder to allow quicker access (or offline access) to previously visited pages. The content is indexed in a database file, known as Index.dat . Multiple Index.dat files exist which index different content—visited content, web feeds , visited URLs , cookies, etc. Prior to IE7, clearing the cache used to clear the index but the files themselves were not reliably removed, posing
4128-556: The World Wide Web Consortium (W3C) or the Internet Engineering Task Force (IETF). Websites often include code to detect browser version to adjust the page design sent according to the user agent string received. This may mean that less-popular browsers are not sent complex content (even though they might be able to deal with it correctly) or, in extreme cases, refused all content. Thus, various browsers have
4224-427: The deprecated Internet Explorer 11 (which reports Mozilla/5.0 (Windows NT 10.0; Trident/7.0; rv:11.0 ) like Gecko ). The problem will self-correct after the release of Firefox 120, as only browsers identifying themselves as 110 through 119 were observed to be affected by it. Computing Computing is any goal-oriented activity requiring, benefiting from, or creating computing machinery . It includes
4320-444: The function of the program it implements, either by directly providing instructions to the computer hardware or by serving as input to another piece of software. The term was coined to contrast with the old term hardware (meaning physical devices). In contrast to hardware, software is intangible. Software is also sometimes used in a more narrow sense, meaning application software only. System software, or systems software,
4416-459: The original equipment manufacturer (OEM) service releases of Windows 95 and later versions of Windows. Microsoft spent over US$ 100 million per year on Internet Explorer in the late 1990s, with over 1,000 people involved in the project by 1999. New feature development for the browser was discontinued in 2016 and ended support on June 15, 2022 for Windows 10 Semi-Annual Channel (SAC), in favor of its successor, Microsoft Edge . Internet Explorer
4512-618: The source code of Spyglass Mosaic , used without royalty in early versions) and security and privacy vulnerabilities , and the United States and the European Union have determined that the integration of Internet Explorer with Windows has been to the detriment of fair browser competition.

4608-513: The "Internet Explorer mode" feature, which enables support for legacy internet applications. This is possible through use of the Trident MSHTML engine, the rendering code of Internet Explorer. Microsoft has committed to supporting Internet Explorer mode at least through 2029, with a one-year notice before it is discontinued. With the release of Microsoft Edge, the development of new features for Internet Explorer ceased. Internet Explorer 11
4704-477: The United States, such as Netscape Navigator and Internet Explorer , previously used the letters U, I, and N to specify the encryption strength in the user agent string. Until 1996, when the United States government allowed encryption with keys longer than 40 bits to be exported, vendors shipped various browser versions with different encryption strengths. "U" stands for "USA" (for the version with 128-bit encryption), "I" stands for "International" –
4800-566: The User-Agent header in their Chrome browser since it was no longer being used to determine browser capabilities and instead mainly being used for passive browser fingerprinting . Google stated that a new feature called Client Hints would replace the functionality of the user agent string. Starting with Chrome 113, released in April 2023, the User-Agent header was partially frozen. The user-agent in newer version of Chrome would remain static except for
4896-583: The W3C XHTML+SMIL ), and the VML vector graphics file format. However, all were rejected, at least in their original forms; VML was subsequently combined with PGML (proposed by Adobe and Sun ), resulting in the W3C-approved SVG format, one of the few vector image formats being used on the web, which IE did not support until version 9. Other non-standard behaviors include: support for vertical text, but in
SECTION 50
#17328548278774992-462: The W3C recommends creating standard HTML markup, allowing correct rendering in as many browsers as possible, and to test for specific browser features rather than particular browser versions or brands. Websites intended for display by mobile phones often rely on user agent sniffing, since mobile browsers often differ greatly from each other. In 2020, Google announced that they would be freezing parts of
5088-512: The Web has encoded within the rules that govern its behavior the knowledge of how to negotiate its half of a request-response transaction; the user agent thus plays the role of the client in a client–server system . Often considered useful in networks is the ability to identify and distinguish the software facilitating a network session. For this reason, the User-Agent HTTP header exists to identify
5184-474: The Windows 10 Long Term Servicing Channel (LTSC) and on Windows Server until 2021, primarily for enterprise purposes. Internet Explorer is still installed in Windows 10 to maintain compatibility with older websites and intranet sites that require ActiveX and other legacy web technologies. The browser's MSHTML rendering engine also remains for compatibility reasons. Additionally, Microsoft Edge shipped with
5280-880: The above titles, and those who work in a web environment often prefix their titles with Web . The term programmer can be used to refer to a software developer , software engineer, computer scientist , or software analyst .

Internet Explorer 5 and 6 had a side bar for web searches, enabling jumps through pages from results listed in the side bar. Pop-up blocking and tabbed browsing were added respectively in Internet Explorer 6 and Internet Explorer 7. Tabbed browsing can also be added to older versions by installing MSN Search Toolbar or Yahoo Toolbar . Internet Explorer caches visited content in
5472-619: The browser (such as icons on the taskbar) would have been removed on June 13, 2023. However, on May 19, 2023 various organizations disapproved, leading Microsoft to withdraw the change. Other versions of Windows that were still supported at the time were unaffected. Specifically, Windows 7 ESU, Windows 8.x , Windows RT ; Windows Server 2008 / R2 ESU, Windows Server 2012 / R2 and later; and Windows 10 LTSB/LTSC continued to receive updates until their respective end of life dates. On other versions of Windows, Internet Explorer will still be supported until their own end of support dates. IE7
5568-514: The browser has 40-bit encryption and can be used anywhere in the world – and "N" stands ( de facto ) for "None" (no encryption). Following the lifting of export restrictions , most vendors supported 256-bit encryption. The popularity of various Web browser products has varied throughout the Web's history, and this has influenced the design of websites in such a way that websites are sometimes designed to work well only with particular browsers, rather than according to uniform standards by
5664-457: The challenges in implementing computations. For example, programming language theory studies approaches to the description of computations, while the study of computer programming investigates the use of programming languages and complex systems . The field of human–computer interaction focuses on the challenges in making computers and computations useful, usable, and universally accessible to humans. The field of cybersecurity pertains to
5760-452: The client software to the responding server. When a software agent operates in a network protocol, it often identifies itself, its application type, operating system , device model, software vendor, or software revision, by submitting a characteristic identification string to its operating peer. In HTTP, SIP, and NNTP protocols, this identification is transmitted in a header field User-Agent . Bots , such as Web crawlers, often also include
5856-560: The computer and its system software, or may be published separately. Some users are satisfied with the bundled apps and need never install additional applications. The system software manages the hardware and serves the application, which in turn serves the user. Application software applies the power of a particular computing platform or system software to a particular purpose. Some apps, such as Microsoft Office , are developed in multiple versions for several different platforms; others have narrower requirements and are generally referred to by
SECTION 60
#17328548278775952-448: The computing power to do the necessary calculations, such in molecular modeling .

The user agent string format is currently specified by section 10.1.5 of HTTP Semantics . The format of the user agent string in HTTP is a list of product tokens (keywords) with optional comments. For example, if a user's product were called WikiBrowser, their user agent string might be WikiBrowser/1.0 Gecko/1.0 . The "most important" product component
7392-635: The inner HTML property, which provides access to the HTML string within an element, which was part of IE 5 and was standardized as part of HTML 5 roughly 15 years later after all other browsers implemented it for compatibility, the XMLHttpRequest object, which allows the sending of HTTP request and receiving of HTTP response, and may be used to perform AJAX , and the designMode attribute of the content Document object, which enables rich text editing of HTML documents. Some of these functionalities were not possible until
7488-616: The introduction of the W3C DOM methods. Its Ruby character extension to HTML is also accepted as a module in W3C XHTML 1.1, though it is not found in all versions of W3C HTML. Microsoft submitted several other features of IE for consideration by the W3C for standardization. These include the 'behavior' CSS property, which connects the HTML elements with JScript behaviors (known as HTML Components, HTC), HTML+TIME profile, which adds timing and media synchronization support to HTML documents (similar to
7584-521: The normal means of launching Internet Explorer in Windows 11 and later versions of Windows 10 , but it is still possible for users to launch the browser from the Control Panel 's browser toolbar settings or via PowerShell . On June 15, 2022, Internet Explorer 11 support ended for the Windows 10 Semi-Annual Channel (SAC). Users on these versions of Windows 10 were redirected to Microsoft Edge starting on February 14, 2023, and visual references to

One well-known communications protocol is Ethernet , a hardware and link layer standard that is ubiquitous in local area networks . Another common protocol is the Internet Protocol Suite , which defines a set of protocols for internetworking, i.e. for data communication between multiple networks, host-to-host data transfer, and application-specific data transmission formats. Computer networking
8064-454: The sharing of resources and information. When at least one process in one device is able to send or receive data to or from at least one process residing in a remote device, the two devices are said to be in a network. Networks may be classified according to a wide variety of characteristics such as the medium used to transport the data, communications protocol used, scale, topology , and organizational scope. Communications protocols define
8160-779: The software. Although bearing a name like NCSA Mosaic, Spyglass Mosaic had used the NCSA Mosaic source code sparingly. The first version, dubbed Microsoft Internet Explorer, was installed as part of the Internet Jumpstart Kit in the Microsoft Plus! pack for Windows 95 . The Internet Explorer team began with about six people in early development. Internet Explorer 1.5 was released several months later for Windows NT and added support for basic table rendering. By including it free of charge with their operating system , they did not have to pay royalties to Spyglass Inc, resulting in
8256-407: The standards, including HTML, CSS, and the DOM. This has resulted in several web pages that appear broken in standards-compliant web browsers and has introduced the need for a "quirks mode" to allow for rendering improper elements meant for Internet Explorer in these other browsers. Internet Explorer has introduced several extensions to the DOM that have been adopted by other browsers. These include
8352-411: The study and experimentation of algorithmic processes, and the development of both hardware and software. Computing has scientific, engineering, mathematical, technological, and social aspects. Major computing disciplines include computer engineering , computer science , cybersecurity , data science , information systems , information technology , and software engineering . The term computing
8448-442: The study of these approaches. That is, the application of engineering to software. It is the act of using insights to conceive, model and scale a solution to a problem. The first reference to the term is the 1968 NATO Software Engineering Conference , and was intended to provoke thought regarding the perceived software crisis at the time. Software development , a widely used and more generic term, does not necessarily subsume
8544-446: The theory of computation and the design of computational systems. Its subfields can be divided into practical techniques for its implementation and application in computer systems , and purely theoretical areas. Some, such as computational complexity theory , which studies fundamental properties of computational problems , are highly abstract, while others, such as computer graphics , emphasize real-world applications. Others focus on
8640-448: The word "Opera" (instead using the string "OPR" to denote the Opera version). Automated web crawling tools can use a simplified form, where an important field is contact information in case of problems. By convention the word "bot" is included in the name of the agent.

8832-1278: Was once the most widely used web browser, attaining a peak of 95% usage share by 2003. It has since fallen out of general use after retirement. This came after Microsoft used bundling to win the first browser war against Netscape , which was the dominant browser in the 1990s. Its usage share has since declined with the launches of Firefox (2004) and Google Chrome (2008) and with the growing popularity of mobile operating systems such as Android and iOS that do not support Internet Explorer. Microsoft Edge, IE's successor, first overtook Internet Explorer in terms of market share in November 2019. Versions of Internet Explorer for other operating systems have also been produced, including an Xbox 360 version called Internet Explorer for Xbox and for platforms Microsoft no longer supports: Internet Explorer for Mac and Internet Explorer for UNIX ( Solaris and HP-UX ), and an embedded OEM version called Pocket Internet Explorer, later rebranded Internet Explorer Mobile , made for Windows CE , Windows Phone , and, previously, based on Internet Explorer 7, for Windows Phone 7 . The browser has been scrutinized throughout its development for its use of third-party technology (such as
8928-436: Was started in the summer of 1994 by Thomas Reardon , who, according to former project lead Ben Slivka, used source code from Spyglass, Inc. Mosaic, which was an early commercial web browser with formal ties to the pioneering National Center for Supercomputing Applications (NCSA) Mosaic browser. In late 1994, Microsoft licensed Spyglass Mosaic for a quarterly fee plus a percentage of Microsoft's non-Windows revenues for
9024-481: Was supported until October 10, 2023 alongside the end of support for Windows Embedded Compact 2013 , while IE9 is supported until January 13, 2026 alongside the end of ESU support for Premium Assurance customers on Windows Server 2008 . Barring additional changes to the support policy, Internet Explorer 11 will be supported until January 13, 2032, concurrent with the end of support for Windows 10 IoT Enterprise LTSC 2021.

The concept of a field-effect transistor was proposed by Julius Edgar Lilienfeld in 1925. John Bardeen and Walter Brattain , while working under William Shockley at Bell Labs , built
9216-621: Was the final release, and Microsoft began the process of deprecating Internet Explorer. During this process, it will still be maintained as part of Microsoft's support policies. Since January 12, 2016, only the latest version of Internet Explorer available for each version of Windows has been supported. At the time, nearly half of Internet Explorer users were using an unsupported version. In February 2019, Microsoft Chief of Security Chris Jackson recommended that users stop using Internet Explorer as their default browser. Various websites have dropped support for Internet Explorer.
