Serial Data Transmission
In serial data transmission each bit is sent one after another by varying the line voltage between 0 & 5 volts for each bit, for two way communication a return wire is required. Serial Data Transmission is commonly used in USB and crossover cables.
Uses
Long distance communication
Why
Only need one signal path per way, can be used to route over telecommunications, saves cost of cabling
But
Signal strength degrades over distance, so repeaters and so on required
