Software application to access information on the World Wide Web
AN web browser (usually called browser) it is a software application to access information about the World Wide Web. When one of the user requests a certain Internet network location, the web browser retrieves the required content from a web server and then displays the result web page on the user’s device.
A web browser is not the same as a search engine, although the two are often confused. For a user, a search engine is just a website, like Google search, Bingor DuckDuckGo, which stores searchable data about other sites. However, in order to connect to a website’s server and view its web pages, the user must have a web browser installed.
Web browsers are used on a variety of devices, including desktops, laptops, tabletsand smartphones. In 2019, about 4.3 billion people used a browser. The more used browser is Google Chrome, with a 64% global market share across all devices, followed by Safari with 17%.
The first web browser, called World Wide Web, was created in 1990 by Sir Tim Berners-Lee. He then recruited Nicola Pellow to write the Line mode browser, which displayed web pages in dumb terminals; was launched in 1991.
1993 was a remarkable year with the launch of mosaic, credited as “the world’s first popular browser”. Its innovative graphical interface has made the World Wide Web system easy to use and therefore more accessible to ordinary people. This, in turn, sparked the Internet boom in the 1990s, when the Web grew at a very rapid pace. Marc Andreessen, the leader of the Mosaic team, soon opened his own company, Netscape, which launched the influenced by the mosaic Netscape Navigator in 1994. The Navigator quickly became the most popular browser.
Microsoft debuted Internet Explorer in 1995, leading to a browser war with Netscape. Microsoft achieved a dominant position for two reasons: it bundled Internet Explorer with its popular Microsoft Windows operational system and did it like freeware without usage restrictions. Eventually, Internet Explorer’s market share reached over 95% in 2002.
In 1998, Netscape launched what would become the Mozilla Foundation to create a new browser using the open code software model. This work has evolved to fire Fox, launched by Mozilla in 2004. Firefox achieved a 28% market share in 2011.
The last major player in the browser market was Google. it is chrome The browser, which debuted in 2008, gained market share in Internet Explorer and became the most popular browser in 2012. Chrome has remained dominant since then.
This process begins when the user enters a standard resource locator (URL), such as
https://en.wikipedia.org/, in the browser. Virtually all URLs on the web begin with
https: which means that the browser will retrieve them with Hypertext Transfer Protocol (HTTP). In case of
https:, communication between the browser and the web server It’s encrypted for security and privacy purposes.
Web pages often contain hyperlinks for other pages and resources. Each link contains a URL and, when clicked or hit, the browser navigates to the new feature. Thus, the process of bringing content to the user begins again.
Most browsers use an internal cache of web page resources to improve load times for subsequent visits to the same page. The cache can store many items, such as large images, so that they do not have to be downloaded from the server again. Cached items are usually stored only as long as the web server stipulates in its HTTP response messages.
Web browsers can generally be configured with a menu. Depending on the browser, the menu may be named settings, optionsor Preferences.
The menu has different types of settings. For example, users can change their home page and standard search engine. They can also change the pattern web page colors and sources. Various network connectivity and privacy settings are also generally available.
During the course of navigation, cookies received from several sites are stored by the browser. Some of them contain login credentials or website preferences. However, others are used to tracking user behavior for long periods, therefore, browsers often provide settings to remove cookies when you exit the browser. The more refined management of cookies generally requires a browser extension.
The most popular browsers have several characteristics in common. They allow users to define favorites and browse a Private mode. They can also be customized with extensions, and some of them provide a synchronization service.
Most browsers have these user interface characteristics:
- Allow the user to open multiple pages at the same time, in different browser windows or in different separators from the same window.
- Back and front to return to the previous page visited or forward to the next.
- AN refresh or recharge to reload the current page.
- AN Stop to cancel the page load. (In some browsers, the Stop button is merged with the Reload button.)
- AN home to return to the user home page.
- THE Address bar to insert the URL of a page and display it.
- A search bar for entering terms in a search engine. (In some browsers, the search bar is merged with the address bar.)
Web browsers are popular targets for hackers, who explore security holes steal information, destroy filesand other malicious activities. Browser vendors regularly fix these security flaws, so users are strongly encouraged to keep their browser software up to date. Other protective measures are antivirus software and avoiding known malware sites.
