Jargon is always contextual, to the application, and the particular [engineering] culture. (Interpreting the parlance in the vernacular, can result in misunderstandings.)
Bias: In an electron tube, a steady DC voltage applied to the
control grid, to establish a reference level for its operation.
Also called grid bias.
Yet...
Bias voltage or current: the DC power
applied to a transistor allowing it to operate
as an active amplifying or signal generating
device. Typical voltage levels in GaAs FETs
used in receivers are 1 to 7 volts between the
drain and source terminals, and 0 to ?5 volts
on, or between, the gate and source terminals.
And yet...
Bias[ing]: the technique of applying a direct current voltage to a transistor or an active network to establish the desired operating point
