In serial data transmission, every byte of data is padded with a '0' in the beginning and one or two '1's at the end of byte because

  1. receiver is to be synchronized for byte reception
  2. receiver recovers lost '0's and '1's from these padded bits
  3. padded bits are useful in parity computation
  4. none of the above
