A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. 1021 is prime.

To determine if 1021 is prime or composite, we can check if it has any factors other than 1 and itself. However, doing a full factorization of 1021 would be time-consuming. So, we can use other methods like checking if it is divisible by any primes less than its square root. After checking, we find that 1021 is a Prime number.
