<storage, hardware>

1. Main memory or RAM. This term dates from the days of ferrite core memory and, like the technology, is now archaic.

Some derived idioms outlived the hardware: for example, "in core" (meaning paged in), core dump, "core image", "core file". Some varieties of Commonwealth hackish prefer store.
