1. storage Main memory or RAM. This term dates from the
days of ferrite core memory; now archaic most places outside
IBM, but also still used in the Unix community and by
old-time hackers or those who would sound like them.
Some derived idioms are quite current; "in core", for example,
means "in memory" (paged in, as opposed to "on disk", pagedout), and both core dump and the "core image" or "core
file" produced by one are terms in favour. Some varieties of
Commonwealth hackish prefer store.

incorporates other circuits on the same chip such as cache,
memory management unit, I/O ports and timers.
