sampled dataData in which the information content exists only for instantaneous values measured or determined at or for discrete intervals.
samplingThe process of digitizing analog information to identify relevant information.
sampling intervalThe reciprocal of the sampling rate, i.e., the interval between corresponding points on two successive sampling pulses of the sampling signal.
sampling periodA defined duration of time, such as one minute, over which CloudWatch computes a statistic.
Sampling RateThe frequency at which analog signals are converted to digital values during digitization. The higher the rate, the more accurate the process.
SAN (Storage Area Network)A high-speed subnetwork of shared storage devices. A storage device is a machine that contains nothing but a disc or discs for storing data.
SandboxA network or series of networks that are not connected to other networks.
SandboxingA method of isolating application modules into distinct fault domains enforced by software.
SanitizationProcess to remove information from media such that information recovery is not possible. It includes removing all labels, markings, and activity logs.
sanitize[In INFOSEC, the] process to remove information from media such that data recovery is not possible.
sanitizingOf a recording medium, erasing or overwriting all data in such a manner that it cannot be recovered, even by extraordinary, e.g., laboratory, means.
SAPFluid content of the xylem and phloem cells of plants. Fluid content of the vacuole generally referred to as cell sap.
