The human readable form of a computer program. This is typically the form in which the program is written, read, and modified by its human author(s)

A level of floating point accuracy that usually requires half the space for each value than does double precision, but provides considerably less precision. For most systems running the SPEC CPU tests from the OSG (e.g., CPU95), single precision implies a 32-bit value

This is an acoustical rating for the reduction in sound of an assembly. It is typically used to denote the sound attenuation properties of building elements, such as walls, floors, and ceilings. The higher the STC, the better the sound-reducing performance of the element

Single-mode fiber

See heat load, sensible

An electrically conducting cable, comprising one or more elements, each of which is individually shielded. There may be an overall shield, in which case the cable is referred to as shielded twisted-pair cable with an overall shield (from ISO/IEC 11801: 1995). Specifically for IEEE 802.3 100BASE-TX, 150 O balanced inside cable with performance characteristics specified to 100 MHz (i.e., performance to Class D link standards as per ISO/IEC 11801: 1995).

A layer 3 interconnection device that appears as a media access control (MAC) to a CSMA/CD collision domain (see IEEE Std 610.7-1995 [B38])

Any component that has the capability of causing failure of a system or a portion of a system if it becomes inoperable

A single fiber path between two medium attachment units (MAUs) or PHYs, including the terminating connectors, consisting of one or more fibers joined serially with appropriate connection devices, i.e., patch cables and wall plates (see IEEE 802.3, Clause 15)

A liquid-cooled server that accepts conditioned coolant
