| SDVO |
Acronym for Serial Digital Video Output. A proprietary Intel technology that additional video signals over a PCI Express slot that contains an Intel 9xx-series chipset. |
| Sensor |
A device that monitors or measures phenomena such as temperature, pressure, light intensity, weight, conductivity, and so on. Sensors may provide digital or analog output proportional to the phenomenon measured. |
| serenum.sys |
A top level filter that enables plug-and-play functionality for serial ports in Microsoft Windows by automatically determining the type of serial device connected. When the serial port enumerator (serenum.sys) loads, it probes the serial port by toggling RTS and DTR while monitoring the incoming data to determine the device type. |
| SI Unit |
From the French Système international d'unités. The International System of Units, abbreviated SI, defines seven base units of measurement involving the number ten and is commonly referred to as the metric system. The seven base units are ampere, candela, kelvin, kilogram, meter, mole, and second. |
| Silent Install |
A software installation that does not display dialog windows or system messages during the installation progress. Also referred to as an unattended installation. |
| Sink |
The ability to allow current to flow through the circuit, usually to ground. |
| Snubber |
A circuit that suppresses inductive "kickback" that may result when inductive loads switch off. Unless snubbed, the kickback voltage can harm the device that drives the load. See: Suppression Diode. |
| Solenoid |
An electrical coil equipped with a magnetic core. Energizing the coil moves the core. Removing the current lets the solenoid core return to its normal position. Solenoids move levers, open valves, and so on. |
| Source (Electrical) |
The ability to provide current flow. |
| SPDT |
Single-Pole Double-Throw - A three-terminal switch or relay in which one central terminal connects to either one of the other two terminals. This type of switch can alternately connect a signal to one of two devices. |
