What is a prime number in networking?

Excuse me, could you please clarify what you mean by "a prime number in networking"? Typically, we associate prime numbers with mathematics, specifically as numbers that are only divisible by one and themselves, with no other factors. However, in the context of networking, it's not immediately apparent how prime numbers would be applied. Could you elaborate on the specific context or scenario in which you're referring to prime numbers in networking? It could be helpful to understand if you're talking about cryptography, encryption protocols, or some other technical aspect of networking.
