Answer 1

copied from some text book

PPP was clearly designed to be implemented in software, not in hardware as
HDLC nearly always is. With a software implementation, working entirely
with bytes is much simpler than working with individual bits. In addition,
PPP was designed to be used with modems, and modems accept and transmit
data in units of 1 byte, not 1 bit.
