Conventional Memory: The first 640 KB of system memory is the (in)famous conventional memory that every PC user has over time grown to know and hate. This is the area that is available for use by standard DOS programs, along with many drivers, memory-resident programs, and most anything else that has to run under standard DOS. It is found at addresses 00000h to 9FFFFh.
Friends. i just strtd to learn the memory architecturer. i am now very good in Hexa, binry, decimal number systems etc. In the above quote when talking about Conventional Memory it says "It is found at addresses 00000h to 9FFFFh". when interpred to decimal it shows 0 to 655,359 .
