What does an 'Active Window' refer to?

An 'Active Window' refers to the window currently in use and has focus, meaning it is the one that is ready to receive input from the keyboard or mouse. When you open multiple windows or applications on your device, there is typically one window that is considered 'active.' This is visually indicated by elements such as a highlighted title bar, and it is the window where any actions you take, like typing or clicking, will apply.

The correct understanding of the term is essential for effective navigation and interaction with software applications, as it allows users to know where their input will be directed. This concept is fundamental in user interface design and is key to efficient task management on a computer.
