Bacteria and archaea primarily reproduce using binary fission. One cell simply splits into two identical cells. If circumstances are right, some bacteria can split in just 20 minutes. After ten hours, one bacterium cell can divide into a billion bacteria cells. Micropia shows you binary fission in action.

Using a pilus, two bacteria make contact with each other and exchange genetic material. This is called conjugation. Some bacteria simply take up DNA which is floating around in their environment.
