Serial and parallel transmission: bitrate, latency and baud rate
Cards in this deck (10)
- 1Serial TransmissionSends each bit along the same channel, one after the other.
Uses a single wire to send bits. - 2Parallel TransmissionSends bits along multiple channels simultaneously, many after the many
Uses multiple wires to send bits. - 3Synchronous TransmissionThe sender and receiver are synchronised by a common clock.
Same clock means they are both always perfectly in sync, they get read/write at precise timings.
Sent in a continuous stream, timing handled by the clock
Ideal, but only possible when same clock is used by sender and receiver - 4Asynchronous TransmissionNo common clock.
The transition between a stop and a start bit is used to synchronise the receiver's clock at the start of each packet.

- 6BitrateTotal bits transmitted per second
- 7LatencyThe delay between the first bit being sent and the first bit being recieved
- 8Baud RateProperty of the physical cable. The number of possible signal changes per second.
- 9How is baud rate used?If a 1 "on" and 0 "off" system is used, baud rate and bit rate is the same. However, signal changes can be very distinct: 0V can be 00, 3V can be 01 etc...
- 10Summary of Network SpeedBitrate = Number of bits per second
Latency = Delay between sending of the first bit and the receiving of that same bit
Baud rate = Number of signal changes per second that a wire can handle
Bandwidth = Maximum possible bitrate of a connection. Proportional to bitrate
