- 1serial transmissionsends each bit along the same channel in order
- 2parallel transmissionsends each bit at the same time along its own channel
- 3parallel transmission's errorcrosstalk - two wires are so close together one induces another current in the other therefore corruption the signal
data skew - not all data arrives at the same time - 4current uses of parallelused in components on PCs
- 5current uses of serialis used for external peripherals (USB, HDMI Ethernet)
- 6Parallel pros and consfaster but more expensive, complex and only reliable over short distances
- 7serial pros and consis suitable over longer distances and is cheaper
- 8Synchronous transmissionuses a clock with no synchronisation is needed between the sender and receiver
- 9Asynchronous transmissiona stop and start bit is used to synchronise the receiver’s clock at the start of each packet
- 10Bitratetotal bits transmitted per second
- 11latencythe delay between the first bit being sent and the first bit being received
- 12Baud ratethe number of signal changes per second that the wire can perform without making the data unreadable
- 13Bandwidthis the maximum possible bitrate of a connection
- 14Bitrate and Bandwidth will never be equal butthey will always be directly proportional
