What does SDLC stand for in networking?

SDLC stands for Synchronous Data Link Control. This is a protocol used in data communications and networking to manage the flow of data between computers. SDLC is particularly important in scenarios where multiple devices are connected and need to communicate effectively without data loss or corruption. It operates in a synchronous manner, meaning it uses timing signals to ensure that the sending and receiving systems are aligned in their communication.

The choice represents a widely used method for controlling data transmission and ensuring reliable delivery over communication links. SDLC allows for both error checking and data framing, making it a fundamental component in various networking protocols.

In contrast, the other options present variations of the term but do not accurately represent the standard acronym recognized within networking contexts.
