Final answer:
You can use the task manager or system monitor utility in your operating system to quickly identify the use of physical memory in your system.
Step-by-step explanation:
To quickly identify the use of physical memory in your system, you can use the task manager or system monitor utility. These tools provide real-time information about the memory usage of running processes and overall system performance.
In Windows, you can access the task manager by pressing Ctrl + Shift + Esc or by right-clicking the taskbar and selecting 'Task Manager.' In the task manager, go to the 'Performance' tab and look for the 'Memory' section.
In Linux, you can use the 'top' command in the terminal or install a system monitor tool like 'htop.' These tools display memory usage information, including the amount of physical memory being used.
