Hi
I am reading an A+ course and in one slide which has a title of
"Division of Memory under DOS"
Momery address----------------- Type of memory
0- 640k ----------------- Conventional or base momory
640k - 1024k ----------------- Upper memory (A through F ranges)
Above 1024k ----------------- Extended Memory
My questions:
1) Why DOS divides momory like that?? I mean if I have my PC with RAM
only 256k then how can DOS go above that range??
2) What does upper memory, and extended memory mean??
Thanks a lot for the helo in advanced.
