1Data compression — Source coding redirects here. For the term in computer programming, see Source code. In computer science and information theory, data compression, source coding or bit rate reduction is the process of encoding information using fewer bits than… …
2Data Carrier Detect — Data Carrier Detect, abbreviated as DCD, or alternately Carrier Detect abbreviated as CD, is a control signal present inside an RS 232 serial communications cable that goes between a computer and another device, such as a modem. This signal is a… …
3Data Terminal Ready — Data Terminal Ready, abbreviated as DTR, is a control signal present inside an RS 232 serial communications cable that goes between a computer and another device, such as a modem. This is a one way high low signal going from the computer to the… …
4Signal integrity — or SI is a measure of the quality of an electrical signal. In digital electronics, a stream of binary values is represented by a voltage (or current) waveform. Over short distances and at low bit rates, a simple conductor can transmit this with… …
5Data remanence — is the residual representation of data that remains even after attempts have been made to remove or erase the data. This residue may result from data being left intact by a nominal file deletion operation, by reformatting of storage media that… …
6Data mining — Not to be confused with analytics, information extraction, or data analysis. Data mining (the analysis step of the knowledge discovery in databases process,[1] or KDD), a relatively young and interdisciplinary field of computer science[2][3] is… …

8Signal box — A signal box or signal cabin is a building from which railway signals and points are controlled. The term signal cabin is used in Ireland, parts of Scotland and in Australia while in North America, the term interlocking tower predominates.… …
9Present Situation Index — A subindex that measures overall consumer sentiments toward the present economic situation and is used to derive (about 40% of) the Consumer Confidence Index, a widely used economic indicator. The sub index is compiled from data gathered from a… …
10Sampling (signal processing) — Signal sampling representation. The continuous signal is represented with a green color whereas the discrete samples are in blue. In signal processing, sampling is the reduction of a continuous signal to a discrete signal. A common example is the …
