OSI Model Question
OSI Model Question
The session ID serves to maintain distinct data flows, whereas port numbers help pinpoint communication methods and host locations. Your response clearly explains the purpose of each identifier, but you could expand by clarifying how they complement one another in system design.
Port numbers aren't always linked to specific protocols. Many services share the same port, like 22 for SSH, yet an SSH server can operate on any available port. It's a good security habit to avoid using standard ports for widely used services when exposing them externally.
I hadn't considered that before. It's a clever suggestion, though. Appreciate the feedback.
