The information in the process table allows the suspended process to be restarted at a later time as if it had never been stopped. Every process has an entry in the table. These entries are known as process control blocks and contain the following information:
Accounting and scheduling information.
SLOT ST PID PGRP UID PRI CPU EVENT NAME FLAGS 0 s 0 0 0 95 0 runout sched load sys 1 s 1 0 0 66 1 u init load 2 s 2 0 0 95 0 10bbdc vhand load sys
SLOT is the entry number of the process.
PID is the process ID.
PGRP is the process Group.
EVENT is the event on which a process is paused or sleeping.
NAME is the name of the process.
FLAGS are the process flags.
A process that has died but still has an entry in the process table is called a zombie process.
