A *(term) for a system in which <em>any</em> object consistently preserves its informational content across some expectable stressing modification, and more generally accross all the modifications that time is likely to bring.

The most frequent such modifications involved when talking about persistence of computer software is the unavoidable shutdown of computer hardware, and the associated termination of low-level computing processes in traditional OS design.

Persistence across unexpected failures is rather called being _(resilient).

See _(Orthogonal Persistence), as opposed to the traditional _(file system) based design for providing persistent memory services.
