SMBus
The System Management Bus (SMBus) is a two-wire interface through which simple power-related chips can communicate with rest of the system. It uses I2C as its backbone. With the SMBus, a device can provide manufacturer information, tell the system what its model or part number is, save its state for a suspend event, report different types of errors, accept control parameters and return its status.

Pronounced smi-dee, an acronym for SCSI Musical Data Interchange. SMIDI is a data interchange standard originated in 1991 by Peavey Electronics that allows large amounts of musical data, such as digital audio files from a sampling keyboard, to be transferred over the SCSI at high speeds between products of different manufacturers. Compared to MIDI, SMDI […]
- SMDS
Short for Switched Multimegabit Data Services, a high-speed switched data communications service offered by telephone companies that enable organizations to connect geographically separate local-area networks (LANs) into a single wide-area network (WAN). Prior to SMDS’s arrival in 1995, the only way to connect LANs was through a dedicated private line. This is still the way […]
- SMIL
Short for Synchronized Multimedia Integration Language, a new markup language being developed by the World Wide Web Consortium (W3C) that would enable Web developers to divide multimedia content into separate files and streams (audio, video, text, and images), send them to a user’s computer individually, and then have them displayed together as if they were […]
- SMI-S
(pronounced as separate letters) Short for Storage Management Initiative Specification, an interface standard that enables interoperability in both hardware and software between storage products from different vendors that an enterprise would use in a SAN environment. The interface provides common protocols and data models that storage product vendors can use to ensure end user manageability […]
- Symmetric Multiprocessing (SMP)
(1) Short for Symmetric Multiprocessing, a computer architecture that provides fast performance by making multiple CPUs available to complete individual processes simultaneously (multiprocessing). Unlike asymmetrical processing, any idle processor can be assigned any task, and additional CPUs can be added to improve performance and handle increased loads. A variety of specialized operating systems and hardware […]
