Unix-like
A Unix-like (sometimes referred to as UN*X or *nix) operating system is one that behaves in a manner similar to a Unix system, although not necessarily conforming to or being certified to any version of the Single UNIX Specification. A Unix-like application is one that behaves like the corresponding Unix command or shell. Although there are general philosophies for Unix design, there is no technical standard defining the term, and opinions can differ about the degree to which a particular operating system or application is Unix-like. Some well-known examples of Unix-like operating systems include Linux and BSD. These systems are often used on servers, as well as on personal computers and other devices. Many popular applications, such as the Apache web server and the Bash shell, are also designed to be used on Unix-like systems. One of the key features of Unix-like systems is their ability to support multiple users and processes simultaneously. This allows users to run multipl ...

Internet Suites
An Internet suite is an Internet-related software suite. Internet suites usually include a web browser, e-mail client (often with a news client and address book), download manager, HTML editor, and an IRC client. The diversity of Internet suite offerings was greatest in the mid-1990s, when proprietary web browser vendors felt it more profitable to sell entire retail suites of applications on compact disc. However, by the end of the first browser war, the Internet suite market dwindled to one or two competitors every few years. In reaction, alternative routes of profit or funding were sought. Opera Software, for example, moved away from offering the Opera Internet suite with embedded advertisements to a completely ad-free product. Mozilla (spun out of Netscape) began to separate the Mozilla Application Suite into separate projects: Firefox, Thunderbird, and Sunbird, but Internet suite development continued with Seamonkey, which is still active under the Mozilla umbrella. A further c ...

Web Browsers

The Usage share of web browsers, most used browser is Google Chrome, with a 65% global market share on all devices, followed by Safari (web browser), Safari with 18%.

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.

Blink (web Engine)
Blink is a browser engine developed as part of the Chromium project with contributions from Google, Meta, Microsoft, Opera Software, Adobe, Intel, IBM, Samsung, and others. It was first announced in April 2013. Naming Blink's naming was influenced by the non-standard presentational blink HTML element, which was introduced by Netscape Navigator and supported by Presto- and Gecko-based browsers until August 2013. Blink has, contrary to its name, never functionally supported the element. History Blink is a fork of the WebCore component of WebKit, which was originally a fork of the KHTML and KJS libraries from KDE. It is used in Chrome starting at version 28, Microsoft Edge starting at version 79, Opera (15+), Vivaldi, Brave, Amazon Silk and other Chromium-based browsers and frameworks. Much of WebCore's code was used for features that Google Chrome implemented differently such as sandboxing and the multi-process model. These parts were altered for the Blink fork, an ...

Chromium (web Browser)
Chromium is a free and open-source web browser project, mainly developed and maintained by Google. This codebase provides the vast majority of code for the Google Chrome browser, which is proprietary software and has some additional features. The Chromium codebase is widely used. Microsoft Edge, Samsung Internet, Opera, and many other browsers are based on the Chromium code. Moreover, significant portions of the code are used by several app frameworks. Google does not provide an official stable version of the Chromium browser, but does provide official API keys for some features, such as speech to text and translation. Licensing Chromium is a free and open-source software project. The Google-authored portion is shared under the 3-clause BSD license. Third party dependencies are subject to a variety of licenses, including MIT, LGPL, Ms-PL, and an MPL/GPL/ LGPL tri-license.

WebKit
WebKit is a browser engine developed by Apple and primarily used in its Safari web browser, as well as on the iOS and iPadOS version of any web browser. WebKit is also used by the BlackBerry Browser, PlayStation consoles beginning from the PS3, the Tizen mobile operating systems, a browser included with the Amazon Kindle e-book reader, and on Nintendo consoles beginning from the 3DS Internet Browser and onward. WebKit's C++ application programming interface (API) provides a set of classes to display Web content in windows, and implements browser features such as following links when clicked by the user, managing a back-forward list, and managing a history of pages recently visited. WebKit started as a fork of the KHTML and KJS libraries from KDE, and has since been further developed by KDE contributors, Apple, Google, Nokia, Bitstream, BlackBerry, Sony, Igalia, and others. WebKit supports macOS, Windows, Linux, and various other Unix-like operating systems. On April 3, ...

Presto (layout Engine)
Presto was the browser engine of the Opera web browser from the release of Opera 7 on 28 January 2003, until the release of Opera 15 on 2 July 2013, at which time Opera switched to using the Blink engine that was originally created for Chromium. Presto was also used to power the Opera Mini and Opera Mobile browsers. Presto is a dynamic engine. Web pages can be re-rendered completely or partially in response to DOM events. Its releases saw a number of bug fixes and optimizations to improve the speed of the ECMAScript (JavaScript) engine. It is proprietary and only available as a part of the Opera browsers. ECMAScript engines A succession of ECMAScript engines have been used with Opera. (For the origin of their names, see Cultural notes below). Pre-Presto versions of Opera used the Linear A engine. Opera versions based on the Core fork of Presto, Opera 7.0 through 9.27, used the Linear B engine. The Futhark engine is used in some versions on the Core 2 fork of Presto, namel ...
