Not all numbers are either prime or composite. The number 1/2 is neither prime nor composite.

If it has no more divisors, then it is prime. If it has more than itself as a divisor, then it is composite.

How can you determine whether a counting number is a composite number?

Start looking for factors; you already know that 1 is a factor, and that the number itself is a second factor (unless the number is 1). As soon as you find a factor that is neither 1 nor the number itself, the number is composite. If you find exactly two factors, the number is prime. If the number has only one factor, the number is 1, which is neither prime nor composite.
