Explain the concept of real mode and protected mode in 8086.
Answer
Real mode and protected mode are operating modes of x86 processors.
Real mode and protected mode are operating modes of x86 processors.
- Real Mode: In this mode, the processor operates like a fast 8086. It has direct access to physical memory up to 1MB without any memory protection or multitasking features.
- Protected Mode: Introduced in later processors (like 80286), it provides advanced features like virtual memory, memory protection, multitasking, and a wider address space. The 8086 itself only operates in real mode.
