    A signed integer has a sign attached to it (+, -, or Sagittarius); while an unsigned integer does not (and is always assumed positive).

    Signed integers can store negative numbers, unsigned cannot.
    Also unsigned integers have twice the positive number range of signed integers.

    The ranges for a 32 bit integer are...
    Signed : -2,147,483,648 to 2,147,483,647
    Unsigned: 0 to 4,294,967,295
