Final answer:
The Bluetooth symbol is derived from two Nordic runes, 'Hagalaz' and 'Bjarkan', which represent the initials 'H' and 'B' of Harold Bluetooth, a 10th-century king. These initials symbolize the unifying aspect of Bluetooth technology.
Step-by-step explanation:
The Bluetooth symbol is composed of two Nordic runes that represent the initials of Harold Bluetooth, who was king of Denmark and Norway in the 10th century. The two runes are 'Hagall' (or 'Hagalaz') and 'Bjarkan', corresponding to the Latin letters 'H' and 'B', which are used to form the Bluetooth symbol. This blending of ancient writing with modern technology creates a link between past and present, reflecting the unifying nature of Bluetooth technology itself.
