- 1Transmitting Data1. the direction of the data transmission
2. the method of transmission (how many bits are sent at the same time)
3. the method of synchronisation between two devices - 2simplex, half-duplex and full-duplexsimplex 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 both directions simultaneously - 3AsynchronousAsynchronous data transmission refers to data being transmitted in an agreed bit patter.
it is a continuous stream of data.
the internal clock makes sure sender and receiver are synchronised with each other. - 4Serialdata is a sent tone bite at a time over a single wire/channel.
bits are sent one after the other in a single stream.
works well over long distances.
this type of data transmission is slow.
An example of its sue is sending data from a CPU and the memory. - 5Parallelseveral bits of data(usually a byte) are sent down several wires or channels at the same time.
works well over short distances.
