Comparison between micro processor Intel and Motorola
No. An 80487 would have been a math coprocessor for an 80486 general-purpose microprocessor...just like the 8087 was the math coprocessor for the 8086 and 8088, the 80287 for the 80286, and the 80387 was for the 80386. The 80486 was the first Intel processor to contain an on-chip math coprocessor, so there wouldn't have been an 80487 because it wasn't necessary.

since it advancd versn of 8086 it got itz name....tat s 8086-2 which becomz 80286
An 80286 has a 24 bit address bus. As such, it can address 224, or 16,777,216, or 16 MB of memory.
memory management and data protection capability
Real mode is a term that was introduced for the 80286 and higher processors. It represents the default (power on) mode of an 80286 or higher processor, as opposed to one of the various protected modes. Real mode does not apply specifically to the 8086/8088. In the 80286 and above, real mode operates very much like the 8086/8088.
