h) All of these

Answer 1

Executing a partially loaded program in memory has benefits like large virtual space, reduced I/O operations, and increased throughput.

Step-by-step explanation:

The ability to execute a program that is only partially in memory provides a number of benefits. Firstly, it allows programs to be created for an extremely large virtual space, as the amount of physical memory does not constrain the program.

Additionally, this approach reduces the need for I/O operations to load or swap user programs in memory, leading to increased efficiency. However, it's important to note that CPU utilization does not decrease with partially loaded programs, as the CPU still needs to process the instructions present in memory.

Furthermore, response time and turnaround time are affected by partially loaded programs. While throughput may increase due to decreased I/O operations, response time can be longer if critical portions of the program are not in memory.

Turnaround time can also increase if there are frequent I/O operations required to load missing program portions.
