Answer / Nitesh Arya
The 8086 operates in two primary modes: Real Address Mode (RAM) and Protected Mode (P Mode). In Real Address Mode, the microprocessor uses a 20-bit base address register to access memory. This mode is limited in terms of address space and protection mechanisms but offers simplicity and compatibility with older systems. Protected Mode, on the other hand, allows for a more secure and efficient management of resources by providing segmented memory addressing, privilege levels, and task switching capabilities.
