1. PID stands for Process ID, Which means Identification Number for currently running process in Memory.

2. PPID stands for Parent Process ID, Which means Parent Process is the responsible for creating the current process(Child Process). Through Parent Process, The child process will be created. If you kill the parent process, the child process is also killed as well.

The PPID is the PID of the processs parent. For example, if process1 with a PID of 101 starts a process named process2, then process2 will be given a unique PID, such as 3240, but it will be given the PPID of 101. Its a parent-child relationship
