@chinmayee.
Cimparator do not have any feedback networks then how we get +v at non-inverting terminal.
Please explain more detail.

The comparator is a device to compare two signal. A and B are to signal it compare three condition.
i.e. A > B, A < B, A = B. Depending value it given output.
i.e. A > B, A < B, A = B. Depending value it given output.

Chinmayee is correct agree.
Comparator just compare the values at input. The output will be the greater one value.

What exactly the comparator is?

When the non-inverting input (V+) is at a higher voltage than the inverting input (V-), the high gain of the op-amp causes the output to saturate at the highest positive voltage it can output. When the non-inverting input (V+) drops below the inverting input (V-), the output saturates at the most negative voltage it can output. Thus we get a rectangular wave.
