Questions about max memory and addresses
1. Suppose that you buy a PC with 32 MBytes of RAM. What is the 8-hexdigit
address of the last byte?
2. Suppose that you discover that RAM addresses 000C0000 to 000C7FFF
are reserved for a PCÕs video adapter. How many bytes of memory is this?
3. Suppose that you have an Intel 8086. Find the five-hex-digit address
that corresponds to each of these segment : offset pairs:
(a) 2B8C:8D21 (b) 059A:7A04 (c) 1234:5678

Re: Questions about max memory and addresses
I could easily give you the answers to all these three questions, but they look suspiciously like homework. Therefore, instead, here are three Wikipedia links that I think contain all information you need to get that done:
http://en.wikipedia.org/wiki/Megabyte
http://en.wikipedia.org/wiki/Hexadecimal
http://en.wikipedia.org/wiki/8086#Segmentation
IMO it wouldn't have been too hard to find them out yourself either.
HTH
I was thrown out of college for cheating on the metaphysics exam; I looked into the soul of the boy sitting next to me.
This is a snakeskin jacket! And for me it's a symbol of my individuality, and my belief... in personal freedom.
