what is Synchronous Data Link Control (SDLC) ?
In: Technology
It’s an old way for devices to talk to one another through wired connections, created by IBM and pretty much only used by IBM.
At one point, there were a lot of competing standards (SCSI, Ethernet, Econet, Token Ring, LocalTalk, RS-232, IEEE 488), but most of these standards have died out, and most devices today talk to each other using Ethernet, or new standards like Wi-Fi (802.11) or ZigBee.
SDLC lives on in a small niche of connecting industrial devices and sensors to their controllers, as part of the BITBUS standard.
