Question

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 channel

This 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 1

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.
