Forward bias implies that your device is sensitive to bias direction and you have selected one of them. There is also an implication that it is probably a steady bias. So forward bias generally implies a dc bias in a selected direction called forward bias in the device you are looking at.
Now the question is actually put the other way round. DC bias means a steady state bias. Whether or not it is forward or reverse bias depends on whether or not the device is sensitive to the direction of bias. If it is not sensitive to that, it isn't forward bias (or reverse bias either). If it is sensitive to bias direction, then it would be in a state of either forward bias or reverse bias, and you would need more information in order to say which one.
So, finally, the phrase "dc biased" is NOT the same thing as "forward biased".

Is less than or greater than zero external voltage applied on diode when you deal with forward biased?
A forward-biased diode has a positive DC on its anode with respect to its cathode.
What happen of a a diode When forward-biased?
when a diode is forward biased it conducts current
What are the characteristics of forward bias?
characteristics of forward biased
Dc resistance of a diode?
It depends on the voltage applied it can be zero to a very finite value. by knowing current and using Boltzmann constant the impedance can be found. Answer: Typically: 700 Ohms when Forward Biased and >2000 Ohms when Reverse Biased.
What is the behavior of a forward and reverse biased diode?
Forward Resistance:def: It is resistance offered by diode to the forward bias is known as forward resistance.This resistance is not the same for the flow of DC as for the changing current. Accordingly this resistance is of two types :1. DC FORWARD RESISTANCE.2. AC FORWARD RESISTANCE.1. DC forward resistance: It is the opposition by diode to the DC. It is measured by the ratio of DC voltages across the diode to the resulting DC current through it.2. AC forward resistance: It is the opposition offered by the diode to the changing current. It is measured by the ratio of change in voltage across diodes to the resulting change in current through diode. The AC forward resistance is more significant as the diodes are generally used with alternating voltage.Reverse Resistance:def: The resistance offered by the diode to the reverse bias is known as Reverse Resistance. It can be DC reverse resistance or AC reverse resistance depending upon whether the reverse bias is direct or changing voltage. Idealy the reverse resistance of a diode is infinte however in practice the reverse resistance is not infinite because for any value of reverse bias, there does exist a small leakage current. It may be emphasized their that reverse resistance is very large compared to the forward resistance.These Definitions are from PRINCIPLES OF ELECTRONICS by V.K MEHTA and ROHIT MEHTA
What do you mean by DC forward voltage?
DC forward voltage is generally related to diodes. It means the voltage across the diode when the diode is forward biased, i.e. when the anode is more positive than the cathode. The forward voltage is the drop across the diode. The amount of drop is a function of current. For typical silicon diodes, the forward voltage drop ranges from 0.6 volts for very small currents, to 1.5 or more volts for large currents.
Approximate voltage across the forward-biased base emitter?
The approximate voltage across the forward-biased base-emitter junction is 0.7 volts.
How do thyrister converters work?
A bridge rectifier rectifies AC to DC. But it can not regulate the DC level. The higher the AC input ..the higher the DC output. No Control. A Thyrister is a member of the four layer device familt called Sillicon CONTROLED Rectifiers. Controller Rectifier. Thyristors have a gate lead .They can not conduct in the reverse direction. Tey may conduct in the forward biased direction if they are gated on. By choosing how early in the forward biased half cycle you gate a thyrister on you CONTROL the level of currnt or voltage out of the bridge .
What does LED do in a circuit?
light up when forward biased
How much voltage is there across a silicon diode when it is forward biased?
0.7 The voltage across a silicon diode when it is forward biased should be greater than or equal (>=) 0.7volts.
Is light emitting diodes emit visible light when forward biased?
It depends on the particular LED. Some of them emit infrared light. But, yes, emission occurs when forward-biased.
Zener diode with its forward biase?
