ER has various meanings in the Computing category. Discover the full forms, definitions, and usage contexts of ER in Computing.
Energy propagated at the speed of light by an electromagnetic field. OR Energy propagated as time-varying electric and magnetic fields. These two fields are inextricably linked as a single entity since time-varying electric fields produce time-varying magnetic fields and vice versa. Light and radar are examples of electromagnetic radiation differing only in their wavelengths (or frequency). Electric and magnetic fields propagate through space at the speed of light.
ComputingThe difference between the correct or desired value and the actual read or value taken. OR A discrepancy between a computed, observed, or measured value or condition and the true, specified, or theoretically correct value or condition. also failure. An error is a deviation from the true value of the measured variable. The difference between the value indicated by the trandsucer response curve contains points of equal maximum value. OR A difference from an average value.
