Processor Mode - IA-32 Virtual Real Mode

The third model in the CPU, virtual real mode, is essential to the backward compatibility of the Windows 32-bit environment. Virtual reality is simply a 16-bit virtual reality environment running in 32-bit protected mode. You've built a virtual real mode session by running a DOS prompt window within Windows. Because protected mode allows for genuine multitasking, you may run many real mode sessions, each with its own program on a virtual PC. These may all execute at the same time, even if other 32-bit programs are running.

It's worth noting that any software running in a virtual real mode window can only access 1MB of memory, which it will believe is the system's first and only megabyte. In other words, if you run a DOS application in a virtual real window, the memory usage will be limited to 640KB. Because in a 16-bit environment, there is only 1MB of total RAM, the upper 384KB is reserved for system usage. Apart from speed, the software operates as if it were on an original real mode–only PC thanks to the virtual real window, which perfectly emulates an 8088 environment. Each virtual machine has its own 1MB address space, a copy of the real hardware BIOS routines, and emulation of all other registers and functionality available in real mode.
