- 1Transmitting dataAgreed factors
1.the direction of the data transmission (i.e. in one direction only or in both directions)
2.The method of transmission (how many bits are sent at the same time)
3.The method of synchronisation between the two devices - 2Simplex, Half-duplex & Full-duplex~Simplex data transmission is one direction only
~Half-duplex transmission is in both directions but not at the same time
~Full duplex data transmission is in the both directions simultaneously - 3AsynchronousAsynchronous data transmission refers to data being transmitted in an agreed bit pattern
data bits (1s and 0s) are grouped together and sent with control bits - 4Synchronous
