Serial: Pertaining to a process in which all events occur one after the other; for example, the serial transmission of the bits of a character according to the CCITT V.25 protocol. Pertaining to the sequential or consecutive occurrence of two or more related activities in a single device or channel.

SHIELDED PAIR. A line consisting of parallel conductors separated from each other and surrounded by a solid dielectric.

Shielded twisted pair: A transmission line composed of a twisted 2-wire metallic transmission line surrounded by a sheath of conductive material that protects it from the effects of external fields and confines fields produced within the line.



SLOT TIME. In networks using carrier sense multiple access with collision detection (CSMA/CD), the length of time that a transmitting station waits before attempting to retransmit following a collision.

SPI. An acronym for 'System Packet Interface', 'Serial Peripheral Interface' or 'SCSI Parallel Interface'. [SPI Bus Definitions]

STUB. Short section of a transmission line used to match the impedance of a transmission line to an antenna. Can also be used to produce desired phase relationships between connected elements of an antenna.

SUPERSPEED USB. A term to describe USB 3.0 revision.

Synchronization bit: A bit used to achieve or maintain synchronism. Note: The term synchronization bit is usually applied to digital data streams.
