Anode and Cathodes are electrodes (simple conductor which allows a flow of charge carries).

Positive and Negatives are charges.

So in a forward biase, positive charge of supply (battery) connected to the anode of device and negative charge of supply connected to the cathode of the device.

Diode is a two terminal device i.e. Anode (First terminal) and Cathode (Second terminal). In electronics, for the conduction to begin in the circuit/device, there should be some supply of current/voltage to be given. Henceforth, Anode is Positive Charge and Cathode is Negative Charge.

During forward bias anode of the diode is connected the +ve supply. In forward bias limiting resistance is connected between the diode and the supply voltage to limits the flow of large current to enter the diode to prevent the diode from damage.

In forward bias more conductivity due to flow of electrons so we have to control the flow of current then we connect the limiting resistor to anode In reverse bias diode is open circuit so we need not limiting tesistor

The applied voltage drives the conduction process. And when cathode or anode are connected which are also polarity terminals, the diode will not conduct because cathode and anode result in current units.

You simply need anode voltage more than cathode voltage to make a diode forward bias may be positive voltage or negative. There is no concept of connecting anode to positive and all.

Anode means +ve and cathode means -ve.

The current will flow from positive to the negative.
If the positive is attached to cathode the reverse current or leakage current will flow.

If we name diode terminals as Va & Vb (anode & cathode volt's).

To make FWD bias condition must be Va > Vb. So obviously +ve supply voltage should give to Va terminal.

When a resistor is placed in between positive supply and diode anode, the resistor will prevent the large flow of current. If not connect the resistor the diode will damage.
