K Desktop Environment 2 was the second series of releases of the K Desktop Environment. There were three major releases in this series.
K Desktop Environment 2 introduced significant technological improvements compared to its predecessor. [1]
DCOP (Desktop COmmunication Protocol), a client-to-client communications protocol intermediated by a server over the standard X11 ICE library. [1]
KIO, an application I/O library. It is network transparent and can access HTTP, FTP, PoP, IMAP, NFS, SMB, LDAP and local files. Moreover, its design permits developers to "drop in" additional protocols, such as WebDAV, which will then automatically be available to all KDE applications. KIO can also locate handlers for specified MIME types; these handlers can then be embedded within the requesting application using the KParts technology. [1]
KParts, a component object model, allows an application to embed another within itself. The technology handles all aspects of the embedding, such as positioning toolbars and inserting the proper menus when the embedded component is activated or deactivated. KParts can also interface with the KIO trader to locate available handlers for specific MIME types or services/protocols. [1]
KHTML, an HTML 4.0 compliant rendering and drawing engine. It supports many Internet technologies, including JavaScript, Java, HTML 4.0, CSS 2, and SSL for secure communications. It is compatible with Netscape plugins such as Flash. KHTML also has the capacity to embed components within itself using the KParts technology. [1]
Konqueror was introduced as web browser, file manager and document viewer. [2] It used KHTML for displaying web pages. [1]
K Desktop Environment 2 also shipped with the initial release of the KOffice suite, consisting of a spreadsheet application (KSpread), a vector drawing application (KIllustrator), a frame-based word-processing application (KWord), a presentation program (KPresenter), and a chart and diagram application (KChart). Native file formats were XML-based. KOffice included a scripting language and the ability to embed individual components within each other using KParts. [1]
The K Desktop Environment 2.1 release inaugurated the media player noatun, which used a modular, plugin design. For development, K Desktop Environment 2.1 was bundled with KDevelop. [3]
The KDE 2.2 release featured up to a 50% improvement in application startup time on Linux systems and increased stability and capabilities for HTML rendering and JavaScript. A number of new plugins were included in Konqueror. KMail received the addition of IMAP support (including SSL and TLS), while KOrganizer got native iCalendar support. Other improvements included a new plugin-based print architecture and a personalization wizard. [4]
After celebrating KDE’s 20th birthday with a re-release of K Desktop Environment 1.1.2 on 14 October 2016, [5] KDE and Fedora contributor Helio Chissini de Castro also did re-releases of Qt2 in October 2017 [6] and KDELibs 2.2.2 in December 2017. [7] [8]

Konqueror is a free and open-source web browser and file manager that provides web access and file-viewer functionality for file systems. It forms a core part of the KDE Software Compilation. Developed by volunteers, Konqueror can run on most Unix-like operating systems. The KDE community licenses and distributes Konqueror under GNU GPL-2.0-or-later.
KHTML is a discontinued browser engine that was developed by the KDE project. It originated as the engine of the Konqueror browser in the late 1990s, but active development ceased in 2016. It was officially discontinued in 2023.
KDevelop is a free and open-source integrated development environment (IDE) for Unix-like computer operating systems and Windows. It provides editing, navigation and debugging features for several programming languages, and integration with build automation and version-control systems, using a plugin-based architecture.
Konsole is a free and open-source terminal emulator graphical application which is part of KDE Applications and ships with the KDE desktop environment. Konsole was originally written by Lars Doelle. It ls licensed under the GPL-2.0-or-later and the GNU Free Documentation License.
The KDE Advanced Text Editor, or Kate, is a source code editor developed by the KDE free software community. It has been a part of KDE Software Compilation since version 2.2, which was first released in 2001. Intended for software developers, it features syntax highlighting, code folding, customizable layouts, multiple cursors and selections, regular expression support, and extensibility via plugins. The text editor's mascot is Kate the Cyber Woodpecker.

Krusader is an advanced orthodox file manager for KDE and other desktops in the Unix world. It is similar to the console-based GNU Midnight Commander, GNOME Commander for the GNOME desktop environment, or Total Commander for Windows, all of which can trace their paradigmatic features to the original Norton Commander for DOS. It supports extensive archive handling, mounted filesystem support, FTP, advanced search, viewer/editor, directory synchronisation, file content comparisons, batch renaming, etc.
Kontact is a personal information manager and groupware software suite developed by KDE. It supports calendars, contacts, notes, to-do lists, news, and email. It offers a number of inter-changeable graphical UIs all built on top of a common core.

Ark is a file archiver and compressor developed by KDE and included in the KDE Applications software bundle. It supports various common archive and compression formats including zip, 7z, rar, lha and tar.
KDE Software Compilation 4 was the only series of the so-called KDE Software Compilation, first released in January 2008 and the last release being 4.14.3 released in November 2014. It was the follow-up to K Desktop Environment 3. Following KDE SC 4, the compilation was broken up into basic framework libraries, desktop environment and applications, which are termed KDE Frameworks 5, KDE Plasma 5 and KDE Applications, respectively.
Kugar is a discontinued tool for generating business quality reports for KOffice. The reports can be viewed and printed. It includes a standalone report viewer and a KParts report viewer. The latter means that any K Desktop Environment 3 application can embed the report viewing functionality and that reports can be viewed using the Konqueror browser.
KDE Platform 4 was a collection of libraries and software frameworks by KDE that served as technological foundation for KDE Software Compilation 4 distributed under the GNU Lesser General Public License (LGPL). KDE Platform 4 was the successor to KDElibs and the predecessor of KDE Frameworks. KDE Platform 4 is the only version of KDE Platform, and in 2013 it was replaced by KDE Frameworks 5.
KDE Plasma 4 is the fourth generation of the KDE workspace environments. It consists of three workspaces, each targeting a certain platform: Plasma Desktop for traditional desktop PCs and notebooks, Plasma Netbook for netbooks, and Plasma Active for tablet PCs and similar devices.
Dolphin is a free and open source file manager included in the KDE Applications bundle. Dolphin became the default file manager of the KDE Plasma desktop environments in the fourth iteration, termed KDE Software Compilation 4. It can also be optionally installed on K Desktop Environment 3. It replaces Konqueror as the default file manager for KDE SC 4, but Konqueror can still be used as an alternative file manager.
K Desktop Environment 3 is the third series of releases of the K Desktop Environment. It was one of the two major desktop environments for GNU/Linux systems between 2002 and 2008. There are six major releases in this series. After the release of KDE 4, version 3.5 was forked into the Trinity Desktop Environment.
K Desktop Environment 1 was the inaugural series of releases of the K Desktop Environment. There were two major releases in this series.
The KDE Software Compilation was an umbrella term for the desktop environment plus a range of included applications produced by KDE. From its 1.0 release in July 1998 until the release of version 4.4 in February 2010, the Software Compilation was simply known as KDE, which stood for K Desktop Environment until the rebrand. The then called KDE SC was used from 4.4 onward until the final release 4.14 in July 2014. It consisted of the KDE Plasma 4 desktop and those KDE applications, whose development teams chose to follow the Software Compilation's release schedule. After that, the KDE SC was split into three separate product entities: KDE Plasma, KDE Frameworks and KDE Applications, each with their own independent release schedules.
KWrite is a lightweight text editor developed by the KDE free software community. Since K Desktop Environment 3, Kwrite has been based on the Kate text editor and the KParts framework, allowing it to use many of Kate's features.
KDE Projects are projects maintained by the KDE community, a group of people developing and advocating free software for everyday use, for example KDE Plasma and KDE Frameworks or applications such as Amarok, Krita or Digikam. There are also non-coding projects like designing the Breeze desktop theme and iconset, which is coordinated by KDE's Visual Design Group. Even non-Qt applications like GCompris, which started as a GTK-based application, or web-based projects like WikiToLearn are officially part of KDE.
