is a data flow direction that allows for simultaneous two-way communication.

Consider a system with the generator bitstream g =1011. We are interested in transmitting the data (or message) m =1101001.a) What is the order of the generator polynomial?b) Perform the cyclic redundancy check (CRC) computation on the message and indicate the bitstream that is transmitted.c) Assume that the bitstream 1101001011 is received at the destination. It should or should not be accepted as being error-free? What is the remainder you got?

Packet-switching networks can provide better resource sharing compared to circuit-switching networks.

The Nyquist rate is the maximum frequency at which a signal can be sampled without distortion.

The process of converting continuous time signals into discrete time signals is called .
