Difference between the communication and transmission.Transmission is a physical movement of information and concern issues like bit polarity, synchronisation, clock etc.Communication means the meaning full exchange of information between two communication media.
(i) Broadcast and (ii) point-to-point
Latest Answer : 1)Broadcast: here the message is sent to all hosts or all links conected to the sendoing computer. Only the host to whom the message is inttended will accecpt and others will reject.2)Point to point: here the sending computer will choose only computer ...
