  Ok i can give the answer upto i know register stores 1 bit of data by alliening the registers no. Of bits will be increased

  Well, a register is nothing but a collection of flip-flops.. so, an 8 bit register may have 8 flip-flops, while a 16 bit register will have 16 flip-flops in it..
  
  You can check the architecture of 8085 and 8086..
  
  And as to what actually happens in a register, it's easy. The states of the flip-flops are changed according to the word that is written.
  When it's a read operation, the states of the flip-flops are read out..

  I think 16-bit register means two 8 bit registers.
  Their arrangement may be of two types..
  little endian and big endian.
  
  Though i am not sure....please check..

  i think we dont exactly combine two 8 bit flipflop's we can make 16 bit register by connecting 16 filpflops in parallel and it becomes as a register each flipflop can store 1 byte of memory
  if we see the flipflop circuit diagram we can know how it stores memory
