Definitions for "Task switching"
Refers to operating systems or operating environments that enable you to switch from one program to another without losing your spot in the first program. Many utilities are available that add task switching to DOS systems. Note that task switching is not the same as multitasking. In multitasking, the CPU switches back and forth quickly between programs, giving the appearance that all programs are running simultaneously. In task switching, the CPU does not switch back and forth, but executes only one program at a time. Task switching does allow you to switch smoothly from one program to another
A method of switching between open windows to view the contents of multiple windows, or copy data. You can use the task buttons in the taskbar to switch from one window to another. You can also click in a window or use Alt Tab.
The ability to switch between applications. The application that you have switched to most recently is the only one that runs; tasks you have switched from are suspended in the background until you switch back to them.
