“Advantages of Digital Communication. The effect of distortion, noise, and interference is much less in digital signals as they are less affected. Digital circuits are easy to design and cheaper than analog circuits. The hardware implementation in digital circuits, is more flexible than analog.” In general, digital is far easier to handle and has (virtually) unlimited precision (limited only by hardware constraints and compute time).
Analog computation takes place at a significant portion of the speed of light (the time it takes for an electrical signal to traverse a circuit). However, it is almost impossible to correct completely for noise, and precision is limited to three (or at most four significant digits).

Water molecules are polar. This means that one end of the molecule is positively charged, while the other is negatively charged. Opposite charges attract. Water molecules on the faucet that are eventually pulled away from the others by gravity will themselves pull together and form round drops because the charged portions of molecule attract the oppositely charged portions of another.
