Is it possible for a process to make a transition from the wait state to the running state?
When a task going to READY state has higher precedence than the currently running task, a dispatch may occur at the same time as the task goes to READY state and it may make an immediate transition to RUNNING state.
What can cause a process to move to the waiting state?
Process moves into the waiting state if it needs to wait for a resource, such as waiting for user input, or waiting for a file to become available. Once the process finishes its execution, or it is terminated by the operating system, it is moved to the terminated state where it waits to be removed from main memory.
Can a process switch state from ready state to blocked state?
Blocked. A process transitions to a blocked state when it cannot carry on without an external change in state or event occurring. For example, a process may block on a call to an I/O device such as a printer, if the printer is not available.
Can a process make transition from ready state to blocked state why or why not?
The OS switches processes between the running and ready states. A running process can switch itself into the blocked state, and the OS may “wake up” a process by switching from blocked to ready state. But there is a complication: The CPU can only run one process at a time.
What is the difference between a process that is ready and a process that is waiting?
Ready: Process can continue. Wait: Process should wait some events and then continue.
When a process is in the ready state what state will it move to next?
Five-State Process Model State Transitions The process is now in ready state, waiting for its execution. Ready -> Running: The short term scheduler or the dispatcher moves one process from ready state to running state for execution.
What are the 5 states of a process?
In two state process model, there are only two states ready and running but in 5 state process model, there are 5 states new, ready, running, blocked, and exit.
What are the two steps of process execution?
The two steps of a process execution are : (choose two)
- ✅ I/O Burst, CPU Burst.
- CPU Burst.
- Memory Burst.
- OS Burst.
What is the ready state of the process?
Reason: When process is started, it directly enters into the ready state, there it waits for the CPU to be assigned. The process which are ready for execution and resides in the main memory are called as ready state processes. A ready state process is run-able but temporarily stopped running to let other processes run.
Is resumed a process state?
The process state consist of everything necessary to resume the process execution if it is somehow put aside temporarily. The process state consists of at least following: Code for the program. Program’s static data.
Which is not a process state?
Reason : Because terimated , running ,blocked are different types of process state .

Which state of process defined the process has finished execution?
TERMINATED – The process has finished execution.
What is the turnaround time of a process?
In general, turnaround time (TAT) means the amount of time taken to complete a process or fulfill a request. The concept thus overlaps with lead time and can be contrasted with cycle time.
What will happen when a process terminates?
What will happen when a process terminates? Explanation: When a process terminates, it removes from all queues. All allocated resources to that particular process are deallocated and all those resources are returned back to OS.
How does a process look like in memory?
A process is more than the program code or a code segment is known as Text Section. This section of memory contains the executable instructions of a program. It also contains constants, macros and it is read-only segment to prevent accidentally modification of an instruction.
What are the four sections of memory in a process?
Memory layout of a process | Operating System
- Stack Section.
- Heap Section.
- Data Section.
- Text Section.
What is basic memory layout of a process?
Memory Layout of a Process Lets explain each component of the above layout one by one : The command line arguments and the environment variables are stored at the top of the process memory layout at the higher addresses. Then comes the stack segment.
