The New World Information and Communication Order (NWICO or NWIO) is a term that was coined in a debate over media representations of the developing world in UNESCO in the late 1970s and early 1980s. The term was widely used by the MacBride Commission, a UNESCO panel chaired by Nobel Peace Prize laureate Seán MacBride, which was charged with creation of a set of recommendations to make global media representation more equitable. The MacBride Commission produced a report titled "Many Voices, One World", which outlined the main philosophical points of the New World Information Communication Order.

- Signal processing is an area of electrical engineering and applied mathematics that deals with operations on or analysis of signals, in either discrete or continuous time to perform useful operations on those signals. Signals of interest can include sound, images, time-varying measurement values and sensor data, for example biological data such as electrocardiograms, control system signals, telecommunication transmission signals such as radio signals, and many others.
- Signals are analog or digital electrical representations of time-varying or spatial-varying physical quantities. In the context of signal processing, arbitrary binary data streams and on-off signals are not considered as signals, but only analog and digital signals that are representations of analog physical quantities.
