while trying to learn pack

I am begining to read bit of low level(assembly) book to just gain some knoweldge on inner workings of memory.

My quesiton is, if machine is 32 bit, even if it's accessing string 'A', it will have to fetch 32 bit (instead of 8 bit that requires to make that letter A ) ?

I know this is not a mailing list for this but i figure since it's closely related to pack, i thought someone would clarify for me.

I am reading "step by step assembly language"... I am not sure i will read the whole thing but i just want to get better inner working of memory as my c book didn't do enough justice.

Please help.

thanks!
