50-825: The Dolphin Browser is a web browser for the Android and iOS operating systems developed by MoboTap Inc . It was one of the first alternative browsers for the Android platform that introduced support for multi-touch gestures. Dolphin Browser uses its native platform's default browser engine . Dolphin Browser supports most web standards . The browser also supports tabbed browsing , voice controls , and touch gestures . It can cache web content for offline use and synchronize data across devices. It supports browser add-ons on Android only. Both iOS and Android versions are proprietary software with optional in-app purchases. There
100-420: A hyperlink , or simply a link , is a digital reference to data that the user can follow or be guided to by clicking or tapping . A hyperlink points to a whole document or to a specific element within a document. Hypertext is text with hyperlinks. The text that is linked from is known as anchor text . A software system that is used for viewing and creating hypertext is a hypertext system , and to create
150-439: A secure and private data transfer. Web pages usually contain hyperlinks to other pages and resources. Each link contains a URL, and when it is clicked or tapped , the browser navigates to the new resource. Most browsers use an internal cache of web page resources to improve loading times for subsequent visits to the same page. The cache can store many items, such as large images, so they do not need to be downloaded from
200-550: A "one-to-many" link, an "extended link" or a "multi-tailed link") is a hyperlink which leads to multiple endpoints; the link is a set-valued function . Tim Berners-Lee saw the possibility of using hyperlinks to link any information to any other information over the Internet . Hyperlinks were therefore integral to the creation of the World Wide Web . Web pages are written in the hypertext mark-up language HTML . This
250-411: A "trail" of related information, and then scroll back and forth among pages in a trail as if they were on a single microfilm reel. In a series of books and articles published from 1964 through 1980, Nelson transposed Bush's concept of automated cross-referencing into the computer context, made it applicable to specific text strings rather than whole pages, generalized it from a local desk-sized machine to
300-561: A document, e.g. a webpage , or other resource, or to a position in a webpage. The latter is achieved by means of an HTML element with a "name" or "id" attribute at that position of the HTML document. The URL of the position is the URL of the webpage with a fragment identifier – "# id attribute " – appended. When linking to PDF documents from an HTML page the " id attribute " can be replaced with syntax that references
350-431: A graphical user interface, the appearance of a mouse cursor may change into a hand motif to indicate a link. In most graphical web browsers, links are displayed in underlined blue text when they have not been visited, but underlined purple text when they have. When the user activates the link (e.g., by clicking on it with the mouse ) the browser displays the link's target. If the target is not an HTML file, depending on
400-718: A hyperlink is to hyperlink (or simply to link ). A user following hyperlinks is said to navigate or browse the hypertext. The document containing a hyperlink is known as its source document. For example, in content from Misplaced Pages or Google Search , many words and terms in the text are hyperlinked to definitions of those terms. Hyperlinks are often used to implement reference mechanisms such as tables of contents, footnotes , bibliographies , indexes , and glossaries . In some hypertext, hyperlinks can be bidirectional: they can be followed in two directions, so both ends act as anchors and as targets. More complex arrangements exist, such as many-to-many links. The effect of following
450-421: A hyperlink may vary with the hypertext system and may sometimes depend on the link itself; for instance, on the World Wide Web most hyperlinks cause the target document to replace the document being displayed, but some are marked to cause the target document to open in a new window (or, perhaps, in a new tab ). Another possibility is transclusion , for which the link target is a document fragment that replaces
500-407: A new window to be created. It is especially common to see this type of link when one large website links to an external page. The intention in that case is to ensure that the person browsing is aware that there is no endorsement of the site being linked to by the site that was linked from. However, the attribute is sometimes overused and can sometimes cause many windows to be created even while browsing
550-541: A page number or another element of the PDF, for example, "# page=386 ". A web browser usually displays a hyperlink in some distinguishing way, e.g. in a different color , font or style , or with certain symbols following to visualize link target or document types. This is also called link decoration . The behavior and style of links can be specified using the Cascading Style Sheets (CSS) language. In
SECTION 10
#1732802531977600-429: A particular website, the browser retrieves its files from a web server and then displays the page on the user's screen. Browsers are used on a range of devices, including desktops , laptops , tablets , and smartphones . By 2020, an estimated 4.9 billion people had used a browser. The most-used browser is Google Chrome , with a 67% global market share on all devices, followed by Safari with 18%. A web browser
650-473: A regular window , but in a special hover box , which disappears when the cursor is moved away (sometimes it disappears anyway after a few seconds, and reappears when the cursor is moved away and back). Mozilla Firefox , IE , Opera , and many other web browsers all show the URL. In addition, the URL is commonly shown in the status bar . Normally, a link opens in the current frame or window, but sites that use frames and multiple windows for navigation can add
700-406: A remote server, a process described by Ars Technica as "an unambiguous breach of privacy ". This breach was patched in the next update. In 2011, Steve Kovach of Business Insider compared Dolphin Browser favorably to Safari and claimed "Dolphin Browser blows Safari out of the water." In 2011, Dolphin Browser was recognized on PC Magazine ' s list of the best free iPhone and iPad Apps of
750-531: A section in the menu for deleting cookies. Finer-grained management of cookies usually requires a browser extension . The first web browser, called WorldWideWeb , was created in 1990 by Sir Tim Berners-Lee . He then recruited Nicola Pellow to write the Line Mode Browser , which displayed web pages on dumb terminals . The Mosaic web browser was released in April 1993, and was later credited as
800-562: A single document (1966), and soon after for connecting between paragraphs within separate documents (1968), with NLS . Ben Shneiderman working with graduate student Dan Ostroff designed and implemented the highlighted link in the HyperTIES system in 1983. HyperTIES was used to produce the world's first electronic journal, the July 1988 Communications of the ACM , which was cited as the source for
850-542: A single site. Another special page name is "_top", which causes any frames in the current window to be cleared away so that browsing can continue in the full window. The term "link" was coined in 1965 (or possibly 1964) by Ted Nelson at the start of Project Xanadu . Nelson had been inspired by " As We May Think ", a popular 1945 essay by Vannevar Bush . In the essay, Bush described a microfilm-based machine (the Memex ) in which one could link any two pages of information into
900-465: A special "target" attribute to specify where the link loads. If no window exists with that name, a new window is created with the ID, which can be used to refer to the window later in the browsing session. Creation of new windows is probably the most common use of the "target" attribute. To prevent accidental reuse of a window, the special window names "_blank" and "_new" are usually available, and always cause
950-795: A sync service and web accessibility features. Common user interface (UI) features: While mobile browsers have similar UI features as desktop versions, the limitations of touch screens require mobile UIs to be simpler. The difference is significant for users accustomed to keyboard shortcuts . The most popular desktop browsers also have sophisticated web development tools . Web browsers are popular targets for hackers , who exploit security holes to steal information, destroy files , and other malicious activities. Browser vendors regularly patch these security holes, so users are strongly encouraged to keep their browser software updated. Other protection measures are antivirus software and being aware of scams . Hyperlink In computing ,
1000-424: A theoretical proprietary worldwide computer network, and advocated the creation of such a network. Though Nelson's Xanadu Corporation was eventually funded by Autodesk in the 1980s, it never created this proprietary public-access network. Meanwhile, working independently, a team led by Douglas Engelbart (with Jeff Rulifson as chief programmer ) was the first to implement the hyperlink concept for scrolling within
1050-437: A typical web browser, this would display as the underlined word "Example" in blue, which when clicked would take the user to the example.com website. This contributes to a clean, easy to read text or document. By default, browsers will usually display hyperlinks as such: When the cursor hovers over a link, depending on the browser and graphical user interface, some informative text about the link can be shown, popping up, not in
SECTION 20
#17328025319771100-579: Is a distinction between the mere act of linking to someone else's website, and linking to content that is illegal (e.g., gambling illegal in the US) or infringing (e.g., illegal MP3 copies). Several courts have found that merely linking to someone else's website, even if by bypassing commercial advertising, is not copyright or trademark infringement, regardless of how much someone else might object. Linking to illegal or infringing content can be sufficiently problematic to give rise to legal liability. Compare for
1150-623: Is added. In certain jurisdictions , it is or has been held that hyperlinks are not merely references or citations , but are devices for copying web pages. In the Netherlands, Karin Spaink was initially convicted in this way of copyright infringement by linking, although this ruling was overturned in 2003. The courts that advocate this view see the mere publication of a hyperlink that connects to illegal material to be an illegal act in itself, regardless of whether referencing illegal material
1200-460: Is based on Mozilla 's code. Both of these codebases are open-source, so a number of small niche browsers are also made from them. The most popular browsers share many features in common. They automatically log users' browsing history , unless the users turn off their browsing history or use the non-logging private mode . They also allow users to set bookmarks , customize the browser with extensions , and can manage user passwords . Some provide
1250-463: Is illegal. In 2004, Josephine Ho was acquitted of 'hyperlinks that corrupt traditional values' in Taiwan . In 2000, British Telecom sued Prodigy , claiming that Prodigy infringed its patent ( U.S. patent 4,873,662 ) on web hyperlinks. After litigation , a court found for Prodigy, ruling that British Telecom 's patent did not cover web hyperlinks. In United States jurisprudence , there
1300-443: Is not allowed without permission. Contentious in particular are deep links , which do not point to a site's home page or other entry point designated by the site owner, but to content elsewhere, allowing the user to bypass the site's own designated flow, and inline links , which incorporate the content in question into the pages of the linking site, making it seem part of the linking site's own content unless an explicit attribution
1350-404: Is not the same thing as a search engine , though the two are often confused. A search engine is a website that provides links to other websites. However, to connect to a website's server and display its web pages, a user must have a web browser installed. In some technical contexts, browsers are referred to as user agents . The purpose of a web browser is to fetch content and display it on
1400-741: Is what a hyperlink to the home page of the W3C organization could look like in HTML code: This HTML code consists of several tags : Webgraph is a graph , formed from web pages as vertices and hyperlinks, as directed edges. The W3C recommendation called XLink describes hyperlinks that offer a far greater degree of functionality than those offered in HTML. These extended links can be multidirectional , remove linking from, within, and between XML documents. It can also describe simple links , which are unidirectional and therefore offer no more functionality than hyperlinks in HTML. Permalinks are URLs that are intended to remain unchanged for many years into
1450-511: Is why a link to a fragment is called an anchor link (that is, a link to an anchor). For example, in XML , the element <anchor id="name" />" provides anchoring capability (as long as the DTD or schema defines it), and in wiki markup , {{anchor|name}} is a typical example of implementing it. In word processor apps, anchors can be inserted where desired and may be called bookmarks . In URLs ,
1500-509: The file type and on the browser and its plugins , another program may be activated to open the file. The HTML code contains some or all of the five main characteristics of a link: It uses the HTML element "a" with the attribute "href" (HREF is an abbreviation for "Hypertext REFerence" ) and optionally also the attributes "title", "target", and " class " or "id": To embed a link into a web page, blogpost, or comment, it may take this form: In
1550-408: The most popular browser. Microsoft debuted Internet Explorer in 1995, leading to a browser war with Netscape. Within a few years, Microsoft gained a dominant position in the browser market for two reasons: it bundled Internet Explorer with its popular Windows operating system and did so as freeware with no restrictions on usage. The market share of Internet Explorer peaked at over 95% in
Dolphin Browser - Misplaced Pages Continue
1600-513: The basis for many other browsers, including Microsoft Edge , currently in third place with about a 5% share, as well as Samsung Internet and Opera in fifth and sixth places respectively with over 2% market share each. The other two browsers in the top four are made from different codebases . Safari , based on Apple 's WebKit code, is the second most popular web browser and is dominant on Apple devices, resulting in an 18% global share. Firefox , in fourth place, with about 3% market share,
1650-659: The early 2000s. In 1998, Netscape launched what would become the Mozilla Foundation to create a new browser using the open-source software model. This work evolved into the Firefox browser, first released by Mozilla in 2004. Firefox's market share peaked at 32% in 2010. Apple released its Safari browser in 2003; it remains the dominant browser on Apple devices, though it did not become popular elsewhere. Google debuted its Chrome browser in 2008, which steadily took market share from Internet Explorer and became
1700-699: The first web browser to find mainstream popularity. Its innovative graphical user interface made the World Wide Web easy to navigate and thus more accessible to the average person. This, in turn, sparked the Internet boom of the 1990s, when the Web grew at a very rapid rate. The lead developers of Mosaic then founded the Netscape corporation, which released the Mosaic-influenced Netscape Navigator in 1994. Navigator quickly became
1750-485: The full linked content is not needed, as is the case when rearranging a page layout . An anchor hyperlink (anchor link) is a link bound to a portion of a document, which is often called a fragment . The fragment is generally a portion of text or a heading, though not necessarily. For instance, it may also be a hot area in an image ( image map in HTML ), a designated, often irregular part of an image. Fragments are marked with anchors (in any of various ways), which
1800-621: The future, yielding hyperlinks that are less susceptible to link rot . Permalinks are often rendered simply, that is, as friendly URLs, so as to be easy for people to type and remember. Permalinks are used in order to point and redirect readers to the same Web page , blog post or any online digital media. The scientific literature is a place where link persistence is crucial to the public knowledge. A 2013 study in BMC Bioinformatics analyzed 15,000 links in abstracts from Thomson Reuters' Web of Science citation index, founding that
1850-438: The hash character (#) precedes the name of the anchor for the fragment. One way to define a hot area in an image is by a list of coordinates that indicate its boundaries. For example, a political map of Africa may have each country hyperlinked to further information about that country. A separate invisible hot area interface allows for swapping skins or labels within the linked hot areas without repetitive embedding of links in
1900-456: The link anchor within the source document. Not only persons browsing the document may follow hyperlinks. These hyperlinks may also be followed automatically by programs. A program that traverses the hypertext, following each hyperlink and gathering all the retrieved documents is known as a Web spider or crawler . An inline link displays remote content without the need for embedding the content. The remote content may be accessed with or without
1950-537: The link concept in Tim Berners-Lee 's Spring 1989 manifesto for the Web. In 1988, Ben Shneiderman and Greg Kearsley used HyperTIES to publish "Hypertext Hands-On!", the world's first electronic book. Released in 1987 for the Apple Macintosh , the database program HyperCard allowed for hyperlinking between various pages within a document, as well as to other documents and separate applications on
2000-412: The median lifespan of Web pages was 9.3 years, and just 62% were archived. The median lifespan of a Web page constitutes high-degree variable, but its order of magnitude usually is of some months. A link from one domain to another is said to be outbound from its source anchor and inbound to its target. The most common destination anchor is a URL used in the World Wide Web . This can refer to
2050-513: The most popular browser in 2012. Chrome has remained dominant ever since. By 2015, Microsoft replaced Internet Explorer with Edge for the Windows 10 release. Since the early 2000s, browsers have greatly expanded their HTML , CSS , JavaScript , and multimedia capabilities. One reason has been to enable more sophisticated websites, such as web apps . Another factor is the significant increase of broadband connectivity in many parts of
Dolphin Browser - Misplaced Pages Continue
2100-479: The same computer. In 1990, Windows Help , which was introduced with Microsoft Windows 3.0 , had widespread use of hyperlinks to link different pages in a single help file together; in addition, it had a visually different kind of hyperlink that caused a popup help message to appear when clicked, usually to give definitions of terms introduced on the help page. The first widely used open protocol that included hyperlinks from any Internet site to any other Internet site
2150-401: The server again. Cached items are usually only stored for as long as the web server stipulates in its HTTP response messages. During the course of browsing, cookies received from various websites are stored by the browser. Some of them contain login credentials or site preferences. However, others are used for tracking user behavior over long periods of time, so browsers typically provide
2200-449: The user following the link. An inline link may display a modified version of the content; for instance, instead of an image, a thumbnail , low resolution preview , cropped section, or magnified section may be shown. The full content is then usually available on demand, as is the case with print publishing software – e.g., with an external link . This allows for smaller file sizes and quicker response to changes when
2250-496: The user's device. This process begins when the user inputs a Uniform Resource Locator (URL), such as https://en.wikipedia.org/ , into the browser. Virtually all URLs on the Web start with either http: or https: which means they are retrieved with the Hypertext Transfer Protocol (HTTP). For secure mode (HTTPS), the connection between the browser and web server is encrypted , providing
2300-497: The various skin elements. Text hyperlink. Hyperlink is embedded into a word or a phrase and makes this text clickable. Image hyperlink. Hyperlink is embedded into an image and makes this image clickable. Bookmark hyperlink. Hyperlink is embedded into a text or an image and takes visitors to another part of a web page. E-mail hyperlink. Hyperlink is embedded into e-mail address and allows visitors to send an e-mail message to this e-mail address. A fat link (also known as
2350-405: The world, enabling people to access data-intensive content, such as streaming HD video on YouTube , that was not possible during the era of dial-up modems . Google Chrome has been the dominant browser since the mid-2010s and currently has a 67% global market share on all devices. The vast majority of its source code comes from Google's open-source Chromium project; this code is also
2400-464: The year, and received a PC Magazine Editors Choice award in 2012. However, in the years since its release it has not had enough users to compete with competitor mobile browsers. As of March 2024, the browser holds a rating of 2.7 out of 5 on the Apple App Store. Web browser A web browser is an application for accessing websites . When a user requests a web page from
2450-684: Was an updated version called Dolphin Browser for Android 2.0 or later. Dolphin Browser Beta was released in May 2012 with the in-house HTML5 engine Jet pack. In December 2013, Dolphin Zero, a version of the app that claims to be private by automatically deleting browser data, was released. In October 2011, privacy concerns were raised about Dolphin browser after it was discovered that all URLs loaded in Dolphin HD were being relayed as plain text to
2500-581: Was the Gopher protocol from 1991. It was soon eclipsed by HTML after the 1993 release of the Mosaic browser (which could handle Gopher links as well as HTML links). HTML's advantage was the ability to mix graphics, text, and hyperlinks, unlike Gopher, which just had menu-structured text and hyperlinks. While hyperlinking among webpages is an intrinsic feature of the web , some websites object to being linked by other websites; some have claimed that linking to them
