The Central Processing Unit (CPU) chip carries out all of the processes for a computer...CPU chips can operate as fast as 3 billion processes a second....For example if you see advertised 2.8GHz CPU, that means the CPU can process 2.8 billion processes a second.
The CPU processes data, so data would be using the CPU.
Check your Task Manager, under the processes tab. You can sort it by Memory or CPU.
The round-robin scheduling algorithm allocates CPU time to processes by sequentially assigning the CPU to processes of equal priority that are in the state of being able to use the CPU. (Not blocked) This works by appearing to evenly distribute the CPU amongst CPU ready processes. Processes that are waiting on something, such as an I/O event, particularly waiting on the user to press Enter, are not considered for allocation. Often, there is a priority assigned to the process, which factors in the allocation strategy. Processes that are mostly I/O intensive tend to have higher priority, giving them good response time. Processes that are mostly CPU intensive tend to have lower priority, so they don't interfere with overall system responsiveness.

You can check how fast your CPU is by using the control panel on your computer. Just click on "my computer" and choose the "system properties" menu. Here you will find the speed of your CPU.
