Computing

In computing, "nothing" can be a keyword (in VB.Net) used in place of something unassigned, a data abstraction. Although a computer's storage hardware always contains numbers, "nothing" symbolizes a number skipped by the system when the programmer desires. Many systems have similar capabilities but different keywords, such as "null", "NUL", "nil", and "None".<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

To instruct a computer processor to do nothing, a keyword such as "NOP" may be available. This is a control abstraction; a processor that executes NOP will behave identically to a processor that does not process this directive.<ref name=arm-manual>NOP - ARM Software Developer Toolkit Reference Guide.</ref>
