1. Generally the ID you mention is called the PID, to distinguish it from the UID or GID or PPID. 2. The Percent of CPU is percentage of a single processor. It is calculated by dividing the CPU used by a process by the time change since when the CPU was last checked, or the Process Start time. It can be greater then 100 percent if two conditions are met. 1. If your computer has multiple processors or cores. 2. The process has multiple threads. A thread is one way for a computer program to divide a task into distinct tasks. Voice Over probably has one thread for speech output one thread for receiving keyboard input , one thread for understanding a windows elements.
