Dolphin is the default file manager for KDE, designed with usability as a primary focus. Dolphin is KDE's default file manager. It aims to improve usability at the user interface level. Dolphin focuses only on being a file manager whereas Konqueror, which was KDE's default file manager in KDE 3 and can still be used for file management, is a universal viewer for many file types. This design approach allows the developers to concentrate on optimizing the user interface for the specific task of file management.
System Monitor is the KDE Task and Performance Monitor. It features a client/server architecture that allows monitoring of local as well as remote hosts.

So, System Monitor is not only a simple task manager but also a very powerful tool to control large server farms.
