Internals

Up to the KDE 4.0, Konsole internal functionality was split into a backend and frontend parts. The backend was represented by a terminal emulator (the DEC VT102 + xterm emulation program) and the frontend that included terminal display and user interface used to display output characters on a window screen or a printer.{{Cite web |title=doc/developer/design/historic/architecture-overview · master · Utilities / Konsole · GitLab |url=https://invent.kde.org/utilities/konsole/-/blob/master/doc/developer/design/historic/architecture-overview |access-date=2022-10-31 |website=GitLab |language=en}}

With newer versions Konsole on Linux systems uses PTY (pseudoterminal interface) abstraction implemented by KPty KDE framework introduced in 2014.{{cn|date=November 2022}}
