How can the duration of a specific process or task in the system be determined?

To determine the duration of a process or task in a system, you can measure the start and end times and then calculate the difference. Different programming languages and environments do this in various ways, but the general approach is as follows:

• Record the start time (for example, using a function to get the current time).
• Execute the process or task.
• Record the end time.
• Calculate the difference between the end time and the start time.

Example in Python:

import time

start_time = time.time()
# task code
time.sleep(2)  # simulate work
end_time = time.time()

duration = end_time - start_time
print(f"Execution duration: {duration} seconds")

In systems with more advanced monitoring, you can use profilers or built-in logging tools for execution time.
