Process Management - Spawning
Multi-tasking is something that allows a user to perform more than one computer task at a time
The Operating System can keep a track of where you are within those tasks
Your allowed to go from one to another without losing information
With Multi-tasking all processes are protected from each other
Multi-tasking also allows processes to “spawn” child processes
The Parent Process will either:
Continue to execute concurrently with its children
Will wait until some or all its children have terminated
