what is the exact difference between process control block and process
descriptor.

i was reading about kernel of linux. it was written there that there
is some thread_info structure which contains the pointer to actual
process descriptor table.it was written that the thread_info lies just
above/below of kernel stack.so definitely thread_info is in main
memory.but what about actual process descriptor task_struct ,where it
is located.if process descriptor resides in main memory...where is the
actual place for it. and yes what about process control
block ...please somebody tell me all this stuff. thank you
