Symmetric data transfer

In symmetric transfers, input and output data have essentially the same form and structure.

Data streams

• maximum size or capacity (P3559)

Signals

• transmitted signal type (P1170)
• received signal type (P1194)
• data transfer speed (P6711)

Electrical (wired) signals

• voltage (P2436)
• maximum current (P8757)
• pinout (P11205)
• connector (P2935)
• connects with (P2789)
• railway signalling system (P3019)

Electromagnetic (including optical) signals

• wavelength (P2808)
• call sign (P2317)
• network bands (P8097)

Asymmetric data transfer

In asymmetric transfers, input and output procedures are fundamentally different from each other, leading to one set of properties for input and another for output.
