1. What is Turnaround Time?

Turnaround Time (TAT) is a performance metric that measures the total time taken from when a process arrives in a system until it completes execution. It is commonly used in operating systems, project management, and service industries to evaluate efficiency.

2. How Does the Calculator Work?

The calculator uses the Turnaround Time formula:

Where:

• \( TAT \) — Turnaround Time (time units)
• \( Completion\ Time \) — Time when process completes execution
• \( Arrival\ Time \) — Time when process arrives in the system

Explanation: This simple subtraction gives the total time the process spent in the system, including both waiting time and execution time.

3. Importance of Turnaround Time Calculation

Details: Turnaround Time is crucial for evaluating system performance, scheduling efficiency, and user satisfaction. Lower turnaround times generally indicate better system performance and faster service delivery.

4. Using the Calculator

Tips: Enter completion time and arrival time in the same time units. Ensure completion time is greater than or equal to arrival time, and both values are non-negative.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between Turnaround Time and Response Time?
A: Turnaround Time measures total time from arrival to completion, while Response Time measures time from arrival to first response or output.

Q2: Can Turnaround Time be negative?
A: No, Turnaround Time cannot be negative as completion time must be greater than or equal to arrival time in any valid scenario.

Q3: What are typical time units used for TAT?
A: Common units include milliseconds (for CPU scheduling), minutes (for service requests), hours (for projects), or days (for manufacturing processes).

Q4: How does TAT relate to Waiting Time?
A: Turnaround Time = Waiting Time + Burst Time (execution time). It includes both the time spent waiting and the time spent executing.

Q5: Why is minimizing TAT important?
A: Minimizing Turnaround Time improves system throughput, user satisfaction, and overall efficiency in process execution and service delivery.
