Mastering KDE helps the reader master the KDE desktop environment for a faster and more robust computing experience. The best thing about Linux is the plethora of choices that users tend to have. Whether it pertains to the kernel modules, or to the desktop environments, there is no shortage of options. Speaking of desktop environments, KDE stands tall as one of the leading options. KDE stands for K Desktop Environment, an open source desktop working platform featuring a graphical user interface (GUI). When KDE was first introduced, it was known as the Kool desktop environment, later renamed KDE. The KDE GUI includes everything a typical user would require, such as a file manager, window manager, help tool, and system settings. KDE is the default desktop environment for various Linux distros, and also has its own flagship distro, KDE Neon, that is covered at length in Mastering KDE. KDE comes with features that give users remote access to other devices, such as computers running Windows, Linux, macOS, or Android smartphones. KDE Connect, a Linux-based application, is one such solution that allows users to transfer data between multiple devices and operate them remotely. This book talks about everyday usage of KDE, including remote access and KDE development. With Mastering KDE, using KDE for day-to-day computing becomes simple and straightforward, which will undoubtedly help readers boost their productivity. The Mastering Computer Science series is edited by Sufyan bin Uzayr, a writer and educator with over a decade of experience in the computing field.
