Machine has "word size"
 . Nominal size of integer - valued data
   . including addresses
 . Most curent machines are 32 bits (4bytes)
   . Limits addresses to 4 GB
   . Becoming too small for memory - intensive applications
 . Hing - end systems are 64 bits (8bytes)
   . potentially address = 1.8 X 10^19 bytes
 . Machines support multiple data formats
   . Fractions or multiples of word size
   . Always integral number of bytes

i found these online, why a "Most curent machines are 32 bits (4bytes)"
will have a limits addresses to 4 GB?? what that mean?? i cannot get any
idea of it. can you help me?
thank you
