- synchronous optical network — (networking) (SONET) A broadband networking standard based on point-to-point optical fibre networks. SONET will provide a high-bandwidth "pipe" to support ATM-based services. The SONET standard will establish a digital hierarchical network with a consistent worldwide transport scheme. SONET has been designed to take advantage of fibre, in contrast to the plain old telephone system which was designed for copper wires. SONET carries circuit-switched data in frames at speeds in multiples of 51.84 megabits per second (Mbps) up to 48 * 51.84 Mbps = 2.488 gigabits per second. Since SONET uses multiple channels to transmit data, each SONET frame can be considered to be a two-dimensional table of bytes that is 9 rows high and 90 columns deep. For every OC-n level, SONET can transmit n number of frames at a given time. Groups of frames are called superframes. SONET is the American version of SDH.
- systems analysis definition — (programming) (SAD) The analysis of the role of a proposed system and the identification of the requirements that it should meet. SAD is the starting point for system design. The term is most commonly used in the context of commercial programming, where software developers are often classed as either systems analysts or programmers. The systems analysts are responsible for identifying requirements (i.e. systems analysis) and producing a design. The programmers are then responsible for implementing it.
- third law of thermodynamics — any of three principles variously stated in equivalent forms, being the principle that the change of energy of a thermodynamic system is equal to the heat transferred minus the work done (first law of thermodynamics) the principle that no cyclic process is possible in which heat is absorbed from a reservoir at a single temperature and converted completely into mechanical work (second law of thermodynamics) and the principle that it is impossible to reduce the temperature of a system to absolute zero in a finite number of operations (third law of thermodynamics)
