title: Word length of computer
body: <p>The largest possible address size, used to designate a location in memory, is typically a hardware word"
  What does the above statement really mean? For example in 8086 microprocessor there are 20 bits of address line and 16 bit is the word length, the address of the location is always 20 bits which is more than the word length bits(16 bits), then how maximum possible address size can be a typically hardware word, it more then the word length bits in this case. 
  I might have misunderstood the above statement please clarify me</p>
