Final answer:
To view running applications, Windows users can use Task Manager, macOS users can use Activity Monitor, and Linux users have options like top, htop, or gnome-system-monitor.
Step-by-step explanation:
If you're looking to see what applications are currently running on your computer, you can use a task manager tool. On Windows, this is known as Task Manager, and it can be accessed by pressing Ctrl+Shift+Esc, or by right-clicking the taskbar and selecting Task Manager. For macOS, the equivalent tool is Activity Monitor, which can be found in the Utilities folder within the Applications folder. On Unix-like operating systems, including Linux distributions, you can use applications like top, htop, or gnome-system-monitor, depending on the graphical interface and system preferences.
