A specific amount of current is allowed to flow through a diode. If the current passing through the diode exceeds this specific value, the diode gets heated and is likely to be damaged. Therefore, in the biasing circuit of a resistance which limits the current passing through the diode within its specific value is called Forward biased diode.
ANSWER: A forward bias diode is just a diode that it is conducting in the forward direction. Positive to anode and negative to cathode
we say a diode to be in forward biased condition when we connect the positive terminal of the diode(anode) to the positive terminal of the power supply and the negative terminal(cathode) to the negative of the power supply. If we do it in the opposite way i.e. connecting positive terminal to the negative powersupply or viceversa it is called to be in reverse biased condition.
In general diodes are configured to work in forward biased condition and not in reverse biased condition. Though there is a certain amount of conductivity in reverse biased condition of a diode due to leakage current.

A bit too complicated to describe here, see the following for lots of detail. http://en.wikipedia.org/wiki/Diode
A: A very low reading in both direction will indicate a shorted diode. A meter is an indicator not a tester keep that in mind

Diodes allow current to flow in only one direction, and if the diode is put a certain way around in the circuit such that it DOES allow current to flow, then it is forward biassed. If the diode is put in the circuit so that it doesn't allow the current to flow, then it is reverse biassed.It is just a term used to describe the orientation of the diode relative to the (conventional) flow of current through the circuit.
A diode might fit this description,

The read type diode are called impatt diode
A diode is used primarily as a Rectifier
