1. Program ID (PID, process handle): It is the only one, and a process must correspond to a PID. PID is generally plastic number
2. Feature information: general system processes, user processes, or kernel processes, etc.
3. Process status: Run, ready, and block, indicating the current operation of the process
4. Priority: Indicates the priority of obtaining CPU control
5. Communication information: Reflecting the communication relationship between processes, because the operating system will provide communication channels
6. Live Reserve: For the process of protecting the obstructive process
7. Resource requirements, allocation control information
8. Process physical information, indicate the program path and name, the process data is in physical memory or in the exchange partition (paging)
9. Other information: work unit, work area, file information, etc.
