Our company is going for Level 3 in CMMI and they are asking my to" Explain the life cycle of a process?"HELP!

Answer 1

this will vary depending on the nature of the process. one explanation related to computer processes below

A process exists in different states according to its past and present status and its present requirements for system resources.

A process in a suspended state is not allowed control of the CPU until it receives an activation signal from a system intrinsic. When it suspends itself, a process must specify the process or processes that are permitted to reactivate it.

A process in an active state is scheduled to gain control of the CPU (awaiting its turn to enter an executing state).

A process in an executing state has control of the CPU. It leaves this state when it has used up its scheduled quantum of time (it enters an active state), when it is blocked or pre-empted by an interrupt, when it suspends itself (it enters a suspended state), or when it is deleted from the system.

During its life span (that is, between creation and deletion), a process progresses through these states in response to the following:

The instruction sequence found in the program code

The actions of other processes
