Which features are associated with time- sharing systems?(Select all that apply) a. Interactive user experience b. CPU time is divided into quantum c. Quick response time d. Multiple users can interact simultaneously

The correct answers are:<br /><br />**a. Interactive user experience** <br />**b. CPU time is divided into quantum** <br />**c. Quick response time** <br />**d. Multiple users can interact simultaneously**<br /><br />### Explanation:<br />Time-sharing systems are designed to allow multiple users to share system resources effectively. These features are associated with such systems: <br />- **Interactive user experience:** Users can interact directly with the system in real-time. <br />- **CPU time is divided into quantum:** The CPU allocates small time slices (quantum) to each task, ensuring fair resource sharing. <br />- **Quick response time:** Time-sharing systems aim to provide fast responses to user inputs. <br />- **Multiple users can interact simultaneously:** Many users can use the system concurrently without significant delays.
