process table A table containing all of the information that must be saved when the CPU switches from running one process to another in a multitasking system. 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: process state - information needed so that the process can be loaded into memory and run, such as the program counter, the stack pointer, and the values of registers. memory state - details of the memory allocation such as pointers to the various memory areas used by the program resource state - information regarding the status of files being used by the process such as user ID. Accounting and scheduling information. An example of a UNIX process table is shown below. SLOT ST PID PGRP UID PRI CPU EVENT NAME FLAGS
