Refer
to section Computer to Computer connectivity via PPI in your course handouts…You
have studied in this course that using parallel port, we can transmit One Byte
at once and thus it is faster than serial communication. You can also find the
details of the procedure that describes how to achieve communication via
parallel port between two computers. It is amazing to see that in this
protocol, Byte is not transmitted as a whole; rather it is transmitted in the
form of Nibbles. You are required to answer the following question.
Is
it possible to transmit One Byte data at once via PPI between two computers? If
yes then How and if not then why?
