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
