A web browser (English: Web Browser, often referred to as a browser) is an application used to retrieve and display information resources of the World Wide Web. These information resources can be web pages, pictures, videos, or other content, which are identified by uniform resource identifiers. Hyperlinks in information resources allow users to easily browse related information. Although the web browser is mainly used to use the World Wide Web, it can also be used to obtain information from web servers in a private network or files in the file system. The mainstream web browsers are Mozilla Firefox, Internet Explorer, Microsoft Edge, Google Chrome, Opera and Safari.


Tim Bernez-Lee invented the first web browser WorldWideWeb in 1990. Then Bernez-Lee hired Nicola Pello to write an LMB browser that can display web pages on dumb terminals, which was released in 1991. In 1993, Mark Anderson released Mosaic-"the most popular browser in the world", which further promoted browser innovation, which made the World Wide Web easier to use. Anderson's browser triggered the Internet boom in the 1990s. Anderson is the leader of the Mosaic team in NCSA. He resigned soon and established his own company, Netscape, and released Netscape Navigator, which was influenced by Mosaic. Netscape Navigator soon became the most popular browser in the world, with a market share of 90%. In response, Microsoft, which missed the Internet wave, hurriedly purchased Spyglass's technology and released Internet Explorer. This triggered the first round of browser wars. Because it is bundled with Windows, Internet Explorer has achieved a dominant position in the web browser market, and its market share reached its peak in 2002 when it exceeded 95%. In 1996, Opera made its debut. It has never been widely used. According to Net Applications statistics, as of February 2002, Opera's market share has been below 2%. In 1998, Netscape faced open source code and created Mozilla Application Suite, but this did not restore Netscape's market share. At the end of 1998, America Online acquired Netscape. In the early stages of development, the Mozilla Application Suite project struggled to attract developers; but by 2002, it had developed into a stable and powerful Internet suite. The emergence of Mozilla Application Suite 1.0 is regarded as its milestone. In the same year, Phoenix was derived (later renamed Firebird, and finally Firefox). Firefox 1.0 was released in 2004. As of 2008, Mozilla and its derivatives accounted for approximately 20% of Internet traffic. Even though the browser market on Macintosh computers was also occupied by Internet Explorer and Firefox, Apple’s self-launched Safari is built into Apple products, especially iPad, iPhone, etc., so it has rapidly expanded in the wave of popularization of Apple products. territory. Safari is based on the KHTML typesetting engine of Konqueror, an open source browser. Safari is the default browser for OS X. Google Chrome is a web browser developed by the leading search engine Google. In May 2012, the StatCounter survey report stated that Chrome's market share has risen to 33%, surpassing Internet Explorer to become the world's largest browser. According to NetMarketShare statistics, in May 2016, the Chrome browser officially took the lead in the global desktop computer market share.


There are various web browsers currently available. Some web browsers use a plain text interface, and they only support HTML; some web browsers have a rich and colorful user interface and support multiple file formats and protocols. Those web browsers that support e-mail, newsgroups, and IRC through components are sometimes referred to as "network kits" rather than just "web browsers." All major web browsers can simultaneously open multiple information resources through multiple windows or multiple tabs, and can also block pop-up advertisements to prevent unnecessary windows from popping up without the user’s consent.

User Interface

The user interface of most major web browsers has the following elements: "Previous" and "Next" buttons. The "Previous Page" button was originally invented by Ted Nelson at Brown University around 1967. "Refresh" button "Home" button Multibox: Display and input URL, if the input is not URL, you can directly use the search engine. Displayable page source code
