1Serial TransmissionBits are tranferred one at a time
2Parallel TransmissionMultiple bits are sent simultaneously over a number of parallel wires
3SkewEach wire in a parallel cable has slightly different properties. Therefore, bits travel down wires at different speeds. Transmission must be over very short distances in order to reduce the effect of the error.
4Integrated CircuitsKnown as a "chip", an IC is made of a semiconductor material called silicon.
The silicon layer assembles millions or billions of tiny resistors, transistors and resistors sending data in parallel.
5BandwidthThe amount of data that can be carried at one time.
6Methods of data transferCopper cable using electrical impulses, wirelessly using radio frequency, Optical fibre using light, infrared.
7SimplexThe data only travels in one direction
8Full DuplexThe data travels in both directions simultaneously.
9Half-DuplexThe data can travel in both directions, but not simultaneously.
10CrosstalkWires in a parallel system interfere with each other.
11Bit rateThe rate of data transfer.
12Baud rateThe rate at which the signal changes.
