1.	If we see practically, parallel data transmission is sent ________(a) over long distances only(b) over short distances only(c) usually over a coaxial cable(d) over a single channelThis question was posed to me by my school teacher while I was bunking the class.My enquiry is from Transmission Bandwidth in portion Angle Modulation of Analog Communications
Answer» Right answer is (b) over short distances only The BEST EXPLANATION: In serial transmission, bits are transmitted one at a TIME over a single channel. In parallel transmission bits are sent simultaneously over their own individual channel. It sent DATA over short distances only.
