(SDLC) An IBM protocol.
A discipline conforming to subsets of the ADCCP of ANSI and the HDLC of the International Organization for Standardization. SDLC manages synchronous, code-transparent, bit-serial communication which can be duplex or half-duplex; switched or non-switched; point-to-point, multipoint, or loop.

- Synchronous digital hierarchy
communications, standard (SDH) An international digital telecommunications network hierarchy which standardises transmission around the bit rate of 51.84 megabits per second, which is also called STS-1. Multiples of this bit rate comprise higher bit rate streams. Thus STS-3 is 3 times STS-1, STS-12 is 12 times STS-1, and so on. STS-3 is the lowest bit […]

- Synchronous idle
character (SYN) The mnemonic for ASCII character 22. [Why?] (1996-06-28)
- Synchronous key encryption
algorithm, cryptography Data encryption using two interlocking keys where enything encoded using one key may be decoded using the other key. This means if someone makes one of the two keys publicly available (as in public-key encryption) and keeps the other private, then anyone may send them a message or data that only they can […]
