In a time-sharing operating system, when the time slot given to a process is completed, the process goes from the RUNNING state to thea)BLOCKED stateb)READY statec)SUSPENDED stated)TERMINATED stateCorrect answer is option 'B'. Can you explain this answer?

Question

Answer

Suspended state because there is no edge between block state to ready state so we need to go first from block state to suspended  state and there is an edge present to go to ready state

Answer

In time-sharing operating system (example in Round-Robin), whenever the time slot given to a process expires, it goes back to READY state and if it requests for same I/O operation, then it goes to BLOCKED state.

Answer

Time-sharing operating system:
A time-sharing operating system allows multiple users to share the resources of a computer system simultaneously. It divides the available processing time into small time slots and assigns a time slot to each process. When a process is given a time slot, it enters the RUNNING state and starts executing its instructions.

Process states:
In a time-sharing operating system, processes can be in different states. The main process states are:

1. NEW: When a process is created, it enters the new state. In this state, the necessary resources are allocated to the process.

2. READY: When the process has been created and allocated resources, but it is waiting for the CPU to execute its instructions, it enters the ready state. Processes in the ready state are waiting for their turn to be executed.

3. RUNNING: When a process is given a time slot and it starts executing its instructions, it enters the running state. In this state, the process is actively using the CPU.

4. BLOCKED: Sometimes, a process may need to wait for some event to occur, such as waiting for user input or waiting for data to be loaded from disk. In such cases, the process enters the blocked state. Processes in the blocked state are not using the CPU and are waiting for the event to occur.

5. SUSPENDED: If a process is temporarily removed from memory and placed on disk to free up memory for other processes, it enters the suspended state. Suspended processes are not actively using the CPU and are stored on the disk.

6. TERMINATED: When a process completes its execution or is explicitly terminated by the user or the operating system, it enters the terminated state. Terminated processes no longer exist in the system.

Transition from RUNNING to READY:
When the time slot given to a process is completed, the process transitions from the RUNNING state to the READY state. This transition occurs because the time slot has expired, and the operating system needs to give other processes a chance to execute. The process moves from the running state to the ready state, where it waits for its next turn to be executed.

Conclusion:
In a time-sharing operating system, when the time slot given to a process is completed, the process goes from the RUNNING state to the READY state. This transition allows other processes to get their turn to execute and ensures fair allocation of CPU resources among multiple processes.
