Question

The operation that can be performed on segments in 80386 real mode is

(a) read

(b) write

(c) execute

(d) all of the mentioned

This question was posed to me by my college director while I was bunking the class.

This interesting question is from Real Address Mode of 80386, Protected Mode of 80386 in division 32-bit Processors-80386, 80387 and 80486 of Microprocessor

Answer 1

The correct answer is:

**(d) all of the mentioned**

In the 80386 processor's real mode, segments can be used for reading, writing, and executing instructions. Real mode is a backward-compatible mode that provides direct access to memory, allowing all these operations to be performed on segment addresses, similar to the operation in earlier x86 processors.
