task switching - To change from one active task running under an operating system to another without losing your place in the first task. Task switching differs from multitasking in that programs switched to the background do not continue to process information but can be brought back to the foreground at any time. For example, if you are working in a word processor and switch to another program, when you return to the word processor, the cursor will be in the same place it was before switching. Compare to multitasking.;
