A process waiting to be assigned to a processor is considered to be in...
Whenever a process executes, it goes through several phases or states. These states have their functions.
New – in this state, process is being created
Running – instructions are being executed
Waiting: the process is waiting for some event to occur such as i/o completion
Ready – The process is waiting to be assigned to a processor
Terminated – The process has finished execution.

Understanding Process States
In operating systems, processes can exist in various states throughout their lifecycle. When a process is waiting to be assigned to a processor, it is in the ready state. Here’s a detailed explanation:
Process States Overview
- Running: The process that is currently being executed by the CPU.
- Waiting: The process that is not currently able to execute due to waiting for an event, such as I/O completion.
- Terminated: The process that has completed its execution and is no longer in the system.
- Ready: The process that is prepared to run but is waiting for CPU time.
Why Ready State?
When a process is created, it is placed in the ready queue. This indicates that:
- The process has all necessary resources and is ready to execute.
- It is simply waiting for the operating system to allocate CPU time.
Key Points of the Ready State
- Queue System: Processes in the ready state are maintained in a queue, waiting for their turn on the CPU.
- Scheduler's Role: The process scheduler is responsible for selecting which process from the ready queue will be executed next.
- Efficiency: The ready state allows for efficient CPU utilization by ensuring that there are always processes available to run when the CPU is free.
In summary, a process waiting to be assigned to a processor is indeed in the ready state, making option 'B' the correct answer. This state is crucial for maintaining the flow of execution in multitasking environments.
