Editing Turing completeness (section)

==Non-mathematical usage==
In [[colloquial]] usage, the terms "Turing-complete" and "Turing-equivalent" are used to mean that any real-world general-purpose computer or computer language can approximately simulate the computational aspects of any other real-world general-purpose computer or computer language. In real life, this leads to the practical concepts of computing [[virtualization]] and [[emulator|emulation]].{{cn|date=June 2022}}

Real computers constructed so far can be functionally analyzed like a single-tape Turing machine (which uses a "tape" for memory); thus the associated mathematics can apply by abstracting their operation far enough. However, real computers have limited physical resources, so they are only [[linear bounded automaton]] complete.  In contrast, the abstraction of a [[universal computer]] is defined as a device with a Turing-complete instruction set, infinite memory, and infinite available time.{{cn|date=April 2024}}
