Which one of the following is not normally shown on the Taskbar?
- A.
Running applications
- B.
Start button
- C.

Printed documents
Correct Answer
D. Printed documentsExplanation
Printed documents are not normally shown on the Taskbar because the Taskbar primarily displays running applications, the Start button, and the system clock. The Taskbar is a graphical user interface element in Windows operating systems that allows users to access and switch between currently running applications, access the Start menu, and view the system clock. Printed documents, on the other hand, are typically accessed and managed through the application that created them, such as a word processor or a PDF viewer, rather than being directly displayed on the Taskbar.Rate this question:

Logging off, restarting, or shutting down the computer may not specifically target the non-responding application and could potentially cause data loss or other complications.Rate this question:

Applications can be installed from the internet, network, or CD as these sources provide the necessary files and resources for installation.Rate this question:
