Aliasing

This article looks at aliasing in conceptual computer science. Aliasing also describes an effect in the area of ​​signal analysis, see also Alias ​​Effect

With aliasing (dt. Overlap / overlay ) is used in the computer science , the existence of multiple identifiers ( descriptors ) designated for a location. Aliasing works, for example, for variables with the same storage location or as a forwarding in network address spaces.

This can lead to opaque errors during runtime , especially in connection with pointers or reference parameters of procedures , because the value is changed at one point, which is not immediately apparent at another point (because of an alias identifier used there).
