(1) (Short Message Service) The common text messaging service available on cellphones and other handheld devices. Due to the billions of cellphones in use, SMS is the most ubiquitous messaging system on the planet. Typing text messages ("texting"), which are limited to 160 characters in length, can be done on basic cellphones with only numeric keys, although QWERTY keyboards make the job easier (see cellphone keyboard). Messages are sent to regular telephone numbers or to shorter numbers for commercial use (see short code).

Like instant messaging, SMS transmits the sender's message to the recipient immediately. It also stores and forwards messages later if a recipient's phone was off when the message was initiated. SMS pricing differs by carrier, which may charge a flat fee per month, a charge per message or include it in a service plan.

Traveling over a control channel separate from the voice channel, SMS was introduced in the GSM system in Europe and migrated worldwide to all cellphone carriers (see GSM). Whereas SMS is text only, MMS supports multimedia (see MMS). See text messaging vs. instant messaging.

(2) (Systems Management Server) Systems management software from Microsoft that was introduced in 1994 for Windows NT Server. It requires a Microsoft SQL Server database and is used to distribute software, monitor and analyze network usage and perform various network administration tasks. In 2007, SMS was superseded by System Center Configuration Manager (see SCCM). See SMS Installer.

(3) (Storage Management System) Software used to routinely back up and archive files. See HSM.

(4) (Storage Management Services) Software from Novell that allows data to be stored and retrieved on NetWare servers independent of the file system the data are maintained in (DOS, OS/2, Mac, etc.). It is used to back up data from heterogeneous clients on the network. Various third-party backup products are SMS compliant. See SIDF.

(5) (System-Managed Storage) Enhanced data management software for MVS mainframes from IBM. Introduced in 1988, it provides functions such as automatically allocating data, which prevents most out-of-space errors when disk volumes become full. See DFSMS.
