The typical query that a DNS server sends to a root name server is called a referral. This is because when a DNS server receives a request for a domain name that does not have the IP address in its cache, it will send a referral to the root name server, asking for the IP address of the top-level domain associated with the requested domain name.

The root name server will then respond with a referral to the appropriate top-level domain name server, which will in turn provide the IP address of the domain name requested. This process can involve both recursive and iterative queries, depending on the configuration of the DNS servers involved. In a recursive query, the DNS server that receives the initial request will continue to query other DNS servers on behalf of the requesting client until it obtains a complete answer. In an iterative query, the DNS server will provide the client with a referral to another DNS server and allow the client to continue the query process.
Overall, DNS is an essential protocol for translating human-readable domain names into machine-readable IP addresses, enabling data to be transmitted across the internet. As such, understanding the different types of queries and referrals used in the DNS process is crucial for maintaining efficient and secure data communication.

To generate prime numbers, you can use a loop that checks if each number is prime or composite.

Here's a Python code example:

```python
def is_prime(n):
   """
   Returns True if n is a prime number, False otherwise.
   """
   if n <= 1:
       return False
   for i in range(2, int(n**0.5)+1):
       if n % i == 0:
           return False
   return True

def generate_primes(n):
   """
   Returns a list of all prime numbers up to n.
   """
   primes = []
   for i in range(2, n+1):
       if is_prime(i):
           primes.append(i)
   return primes
```

The `is_prime` function checks if a given number `n` is prime by iterating through all numbers from 2 to the square root of `n` and checking if any of them divide `n` evenly. If so, the function returns `False`. If none of them divide `n` evenly, the function returns `True`.

The `generate_primes` function generates all prime numbers up to a given number `n`. It does this by iterating through all numbers from 2 to `n` and checking if each one is prime using the `is_prime` function. If a number is prime, it is added to a list of primes. Once all numbers have been checked, the function returns the list of primes.

You can call the `generate_primes` function with any positive integer `n` greater than 1 to generate a list of prime numbers up to `n`. For example:

```python
primes = generate_primes(20)
print(primes) # prints [2, 3, 5, 7, 11, 13, 17, 19]

If language A and its complement are both recognizable, then A must be decidable. This is because the ability to recognize both A and its complement implies that we can construct two Turing machines that will determine whether any given input string is in A or not in a finite amount of time.

If language A and its complement are both recognizable, then A must be decidable. This is because if A and its complement are both recognizable, then we know that A is recursively enumerable, and its complement is also recursively enumerable.

Recall that a language is decidable if and only if it is both recursively enumerable and its complement is also recursively enumerable. In this case, since A and its complement are both recursively enumerable, we can construct two Turing machines: one to recognize A and one to recognize its complement.

We can then run both of these machines on any input string and observe their behavior. If the input string is in A, then the machine recognizing A will eventually halt and accept the string. If the input string is not in A, then the machine recognizing its complement will eventually halt and accept the string. Therefore, we can determine whether an input string is in A or not in a finite amount of time, which means that A is decidable.
