Serial+Data+Transmission

Serial Data Transmission is when single bits of binary digits are sent one by one along a single wire by making diffent voltages on the wire. The image down below shows the serial data transmission of the letter J. The way the binary is transmitted is that 5 volts = 1 and 0 volts = 0. The alternative to serial data transmission is parrllel data transmission there are some advantages of serial data transmission is that it can transmit data over a longer distance as there is only 2 cables one going one way the other going the other way.
