Morphology
read/write + head
The meaning is directly compositional: 'read/write' specifies the functions and 'head' denotes a part of a device, so a learner who knows 'read', 'write' and 'head' can infer 'the part that reads and writes data'. This function+part construction is common in technical vocabulary and cross-linguistically transparent, making it accessible to a B1 learner.
Etymology
Read/write head comes from early disk drives: it was a tiny physical 'head' that hovered over a spinning disk and literally read and wrote information by sensing or changing magnetic patterns. So, the name now means the small part of a storage drive that handles 'data'.
