CPU time

The "Processor " (English " CPU Time" ) refers to the time measured in hours, minutes and seconds, in which a running program has actually sent since the last startup commands to the processor. This sum is almost always lower than the total duration of the program, since this hardly constantly sends commands to the processor, even with heavy use.

Processor time as intensity measure

For multitasking various programs access alternately on the processor. In a concurrent access to the program assigned by the operating system " priority " (english process priority), which program an incoming command is executed first decides. This priority has been established for most programs and can only be changed in a few by the user.

The sum of processor time there is also good information about the frequency or intensity (keyword computationally intensive ), with which a program uses the processor. Especially helpful to know which is in so-called background programs, such as a resident virus scanner, which sends automatically without user input in the background his commands to the processor. Good Task Manager show these values ​​individually.
