Turnaround time in CPU scheduling refers to the total amount of time taken from the submission of a process to its completion. It includes all phases of execution, such as the waiting time in the queue, the time spent in execution, and any time spent in I/O operations.
Mathematically, the turnaround time can be expressed as:
\[ \text{Turnaround Time} = \text{Completion Time} - \text{Arrival Time} \]
Where:
- **Completion Time** is the time at which the process finishes its execution.
- **Arrival Time** is the time at which the process arrives in the ready queue.
Essentially, the turnaround time is an important metric in scheduling algorithms as it helps to evaluate the efficiency of the CPU and the overall performance from a user's perspective. Lower turnaround times generally indicate better performance, as processes are being completed more quickly.
