The putative tendency of content in storage to become corrupt over time.
The tendency of software in storage to develop bugs over time due to minor incompatibilities with newer operating environments.
Bit rot, also bit decay, data rot, or data decay, is a colloquial computing phrase for the gradual decay of storage media or a explanation for the degradation of a software program over time, even if ‘nothing has changed’.
The New Hacker's Dictionary
[common] Also bit decay. Hypothetical disease the existence of which has been deduced from the observation that unused programs or features will often stop working after sufficient time has passed, even if ‘nothing has changed’. The theory explains that bits decay as if they were radioactive. As time passes, the contents of a file or the code in a program will become increasingly garbled.There actually are physical processes that produce such effects (alpha particles generated by trace radionuclides in ceramic chip packages, for example, can change the contents of a computer memory unpredictably, and various kinds of subtle media failures can corrupt files in mass storage), but they are quite rare (and computers are built with error-detecting circuitry to compensate for them). The notion long favored among hackers that cosmic rays are among the causes of such events turns out to be a myth; see the cosmic rays entry for details.The term software rot is almost synonymous. Software rot is the effect, bit rot the notional cause.
