bits are sent one after another along the same data line
2 of 15
Parallel transmission
several bits (e.g. one byte of data) are sent simultaneously along separate lines or channels
3 of 15
skew
As each individual wire has slightly different properties, bits travel at slightly different speeds along each of the wires.
4 of 15
crosstalk
This refers to electromagnetic interference between two adjacent channels or parallel wires. It gets more pronounced as the frequency (speed of transmission) increases
5 of 15
Synchronous transmission
Synchronous data transmission: all data transfers are timed to coincide with an internal clock pulse
6 of 15
Asynchronous transmission
Using asynchronous data transmission, each byte is sent separately the moment it is available instead of waiting for a clock signal
7 of 15
The parity bit
The parity bit or check bit is added as the 8th bit as a form of error detection
8 of 15
Latency
Latency is the time delay between the moment the first byte or packet of a communication starts and when it is received at its destination
9 of 15
Protocol
All communications between devices require that the devices agree on the format of the data
10 of 15
Bit rate
the number of bits (0's and 1's) transmitted in one second over a wired or wireless data link
11 of 15
baseband
Using baseband, at each signal change one bit is transmitted
12 of 15
Baud rate
Baud rate is the rate at which the signal in a communications channel changes state
13 of 15
Broadband
Using baseband, at each signal change one bit is transmitted
14 of 15
Bandwidth
A measure of the maximum capacity of a given communication channel, usually measured in bps
