Synchronous Data Link Control was originally designed to connect one computer with multiple peripherals via a multidrop bus. The original "normal response mode" is a primary-secondary mode where the computer (or primary terminal) gives each peripheral (secondary terminal) permission to speak in turn. Because all communication is either to or ...

On the other hand, a network attacker may use a special type of service scanner, known as a vulnerability scanner, to find devices that have not been patched to find a known vulnerability.
