Final answer:
A process that is not in main memory and not immediately available for execution but not waiting for an event is termed a Suspended Process.
Step-by-step explanation:
The question pertains to the state of a process in an operating system and its relation to being stored in memory. When a process is not in main memory and is not immediately available for execution, but is not awaiting an event either, it is known as a Suspended Process. Contrary to a Suspended Process, a Blocked Process is awaiting an event (such as the completion of I/O operation), a Ready Process is in memory and prepared to execute as soon as the processor is available, and a Dormant Process is one that has been initiated but is not yet ready or waiting to be executed.
