Can someone explain what dipole is?

A dipole moment is where one atom is more electronegative than the other, which results in separation of positive and negative charges.

Dipole moments occur in covalent bonds where electrons are not shared equally. The difference in electronegativity creates a charge difference and dipole moments is the measure of this charge difference. A dipole moment is the charge times the distance between the atoms.

Dipole moment occurs when electrons are not shared equally. It is caused by the difference in electronegativity of atoms. A more electronegative atom pulls electrons more, thus having a partial negative charge, causing the other atom to have an equal but partial positive charge.

In the example of water, (H2o) there are two dipole moments, a partial positive with both hydrogen atoms and a partial negative dipole over the Oxygen atom. This configuration overall is considered non-polar even know there is a dipole moment.
