In water and many other compounds hydrogen and oxygen are held by covalent bonds.
Between water molecules and between other polar molecules hydrogen of one molecule and oxygen of a different molecule are held by hydrogen bonds.
The weak bonds that hold two or more water molecules together are called hydrogen bonds. These bonds form due to the attraction between the slightly positive hydrogen atom of one water molecule and the slightly negative oxygen atom of another water molecule.
Covalent bonds hold hydrogen and oxygen atoms together in a water molecule (H2O). In a covalent bond, atoms share electrons to achieve a stable electron configuration.
Hydrogen bonds hold separate water molecules together. This type of bond forms between the partially positive hydrogen atom of one water molecule and the partially negative oxygen atom of another water molecule.
Water forms polar covalent bonds between hydrogen and oxygen atoms. The oxygen atom attracts electrons more strongly than the hydrogen atoms, leading to a partial negative charge on the oxygen and a partial positive charge on the hydrogen atoms.
A hydrogen bond is the attractive interaction of a hydrogen atom with an electronegative atom(<-wikipedia). Hence, in a water molecule the positive hydrogen atoms are attracted to the negative oxygen atoms. Just know that the hydrogen bond mentioned above is not a chemical bond. If it were, it wouldn't be water anymore. Another force between water molecules are London Dispersion Forces.

Water molecules are composed of one oxygen atom and two hydrogen atoms. The bonds within a water molecule are covalent bonds, which are strong bonds that hold the atoms together. These covalent bonds involve the sharing of electrons between the oxygen and hydrogen atoms within the water molecule.
A water molecule has two types of bonds: covalent bonds between the oxygen atom and the hydrogen atoms within the molecule, and hydrogen bonds between water molecules. The covalent bonds hold the atoms within a water molecule together, while hydrogen bonds are formed between the positively charged hydrogen atoms of one water molecule and the negatively charged oxygen atom of another water molecule.
the purpose for hydrogen bonds is to hold the 2 strands of DNA together
Hydrogen bonds hold water molecules together. Hydrogen bonds are very strong, which accounts for the high boiling point of water (100˚C, 212˚F), and its ability to remain liquid water over such a huge range of temperatures. The negative oxygen and positive hydrogen in water form hydrogen bonds with each other.
