1Serial data transmissionBits are sent one after another along the same data line
2Parallel data transmissionSeveral bits are sent simultaneously along separate lines or channels
3Problem with parallel transmissionUnreliable on short distance and very high frequencies
4Synchronous data transmissionAll data transfers are times to coincide with an internal clock pulse
5Asynchronous data transmissionEach byte is sent separately the moment it is available instead of waiting for a clock signal
6LatencyThe time delay between the moment the first byte or packet of a communication starts and received at its destination
7ProtocolIt is a set of rules that govern the transmission between devices
8Bit rateThe number of bits transmitted in one second over a wired or wireless data link
9Baud rateThe rate at which the signal in a communications channel changes state
10BandwidthA measure of the maximum capacity of a communications channel
