Morphology

bulkhead = bulk + head (opaque) = bulk + head

Although historically a compound, the nautical meaning 'partition/wall in a ship' is not predictably recoverable for modern learners from 'bulk' and 'head'.

Etymology

Bulkhead in computing borrows the ship image and the parts bulk ('main load') and head ('end' or 'wall'): think of a wall on a ship that stops damage. In computing a bulkhead is a design that keeps problems in one part so the rest can keep working.
