Detailed explanation-1: -Whenever the processes in main memory are entered into the blocked state, the operating system suspends one process by putting it in the Suspended state and transferring it to disk. The free space present in the memory is used for bringing another process.
Detailed explanation-2: -Once the operating system is loaded, the boot loader transfers control to it and is no longer needed. The operating system will initialize itself, configure the system hardware (e.g., set up memory management, set timers, set interrupts), and load device drivers, if needed.
Detailed explanation-3: -When a program is loaded into the memory and it becomes a process, it can be divided into four sections ─ stack, heap, text, and data.
Detailed explanation-4: -When a process is suspended (to either waiting or ready state), the values of the physical registers must be copied to the PCB, from which the registers can be restored when the process restarts in the running state. The other main data of the process is stored in main memory.
