What happends when operating system is loaded into ram?

When an operating system is loaded into RAM, it transfers its core components and necessary files from storage (like a hard drive or SSD) into the system's volatile memory. This allows the CPU to quickly access and execute the OS instructions, facilitating efficient management of hardware resources and user applications. The OS initializes system processes, manages memory allocation, and sets up user interfaces, enabling users to interact with the computer. Once loaded, the OS remains in RAM until the system is powered off or restarted.
