In forward bias, the electrons attracted by the positive terminal and holes are attracted by negative terminal so conductivity more as compared to reverse bias.

Forward bias means anode of the diode is connected to the positive terminal and cathode of the diode is connected to the negative terminal, as a result of which more electrons are supplied 4m the negative terminal (i.e. 4m cathode to anode) and are attracted by the +ve terminal of the battery....this leads to the flow of current from anode to cathode and hence diode conducts.

A diode conducts when it is forward-biased, and the anode is connected through a limiting resistor.
