What is the purpose of pressing Alt + Tab on the keyboard of a computer system?

Correct option is A

The correct answer is:(a) Switches between open applications

Explanation:
When you press Alt + Tab, it allows you to cycle through and switch between the different open applications or windows on your computer. This keyboard shortcut is commonly used to quickly navigate between tasks without needing to use the mouse. Holding the Alt key and pressing Tab multiple times will cycle through all open programs, allowing you to select the one you want to bring to the forefront.

Information Booster:

• Alt + Tab helps you switch efficiently between running applications without having to minimize or close windows.
• The Task Switcher appears when Alt + Tab is pressed, showing all open windows and allowing the user to select the one to switch to.
• This shortcut is available on most operating systems, including Windows, Mac (with different shortcuts), and Linux.
• Alt + Shift + Tab can be used to switch between applications in reverse order.

Additional Information:

• (b) Shuts down the system: This is incorrect because Alt + F4 is the shortcut used to close or shut down a system or window.
• (c) Minimises all windows: The shortcut for minimising all windows is Windows key + D.
• (d) Opens Task Manager:Ctrl + Shift + Esc is the shortcut to open the Task Manager directly.
