n. Main storage or RAM. Dates from the days of ferrite-core
memory; now archaic as techspeak 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' (as opposed to 'on
disk'), and both {core dump} and the 'core image' or 'core
file' produced by one are terms in favor. Commonwealth hackish
prefers
store.
