All data is stored in a computer as 0s and 1s. In order to make this more efficient, certain sets of bits can mean different things depending on what the data type is. Some languages, such as Java, make sure the programmer doesn't confuse these types and mess up the data. However, other languages allow you to do things like multiply a string and an array. If you don't pay careful attention to data types, you can easily end up with useless data.
