Detailed explanation-1: -Faster data transfer: Since multiple bits are sent at once, parallel data transmission is faster than serial transmission.
Detailed explanation-2: -When data is sent using parallel data transmission, multiple data bits are transmitted over multiple channels at the same time. This means that data can be sent much faster than using serial transmission methods.
Detailed explanation-3: -modulation technique provides the fastest transmission speed.
Detailed explanation-4: -A serial transmission transfers data one bit at a time, consecutively, via a communication channel or computer bus in telecommunication and data transmission. On the other hand, parallel communication delivers multiple bits as a single unit through a network with many similar channels.
