3) a) A sender wants to transmit a 10-bit binary data (1101011011). The sender uses CRC for error detection and hence uses a bit pattern of 10011 as the divisor. How many bits are actually transmitted by the sender? If all bits are received correctly, what is the bit pattern that the receiver receives? How many bit errors can the receiver detect using this mechanism? Name another error detecting technique and an error correcting technique. (1+6+2+2]
