What is CPU time?
Central processing unit (CPU) Computer is where most low -level calculations take place. CPU time is required to perform a CPU to perform its part of the process. This period is part of the past time, a number that includes CPU use, input and output time and other computer interactions. The past time covers the entire program from start to finish. CPU time was a relatively simple calculation, but with the advent of multi -core processors became more complicated. Regardless of the time that lasts for the entire operation, CPU time measures only from the point where it reaches the processor until it completes the processor. It is usually measured as time, percentage of processor capacity or in ticks of hours.
In general, CPU time measurement is used in real time only when people need to read time. Other computers and programs generally consider other time to determine time to determine time. Since most computers do not think in conventional time frames, many programs that measure time in realIn real time, he uses one of the other methods and converts these results.
TimeCPU time is expressed as a percentage of capacity when the overall use of the processor is the target number. This is another way of displaying information for the human audience. This method is usually used to find the total CPU load. These numbers are used to find the top and peace of servers or simply to monitor the performance of a personal computer.
TRACKS CLACK is the most difficult method of CPU time measurement that people should follow, but are usually the most useful for other computer programs. The clock ticks are a variable time affected by the processor speed. The faster the processor, the faster the clock ticks. These ticks are monitored by other programs to use processors and prevent a close place.
past time, also known as time for wall clock or real time, is after cellou time when the process is carried out from start to finish. With the past time, the process has been measured since it begins, regardless of its original point, to the end. This time it can include anything from mouse clicks to CPU processing or time access to disk. Until the arrival of multi -core processors, the past time has always been equal or greater than the CPU time.
multi -core processors are vomited to CPU time. When using multiple cores, the CPU time is the total time spent on each processor. Because they can receive a single command and divide it into multiple processors, it is possible that the total time was higher than the overall time to perform the process.
